Chapter 1: When the truth is discovered

Cannon Part:

"Hyoudou Issei…this is a message for you. —Starting with Sirzechs Lucifer, the current Leviathan, and current Asmodeus, these three Maou's, as well as the leaders of various factions, have accompanied Trihexa to another dimension." Vali explained

"What!?" Shouted Issei as Vali's words greatly surprised me. To truly keen indeed damage from Trihexa, which had split itself apart to a minimum, it was transported into a dedicated isolation barrier. And to contain it, warriors were elected from each of the various factions to fight against it. Those people were the higher-ups of each faction. Among them were the Maou's like Sirzechs-sama, Serafall-sama, Michaelsama, and that old man Odin. After that, Vali explained to me the last actions the higher-ups took. …I finally remembered the scene from that time. Because I was paralyzed and had collapsed on the floor due to Dragon Deification, Sirzechs-sama spoke with a parting tone while beside me. So that…wasn't a dream. …Why is it like this, Sirzechs-sama…. Seeing my immense shock,

Vali continued, "Azazel also went in."

"What!! Sensei too? T-That…" "…Right now, we can no longer see him." .... …I looked up at the ceiling. …I couldn't say anything. I could not utter a single word. Even if I wanted to complain to him, he's no longer here now…? I covered my face with my hand and asked Vali, "How long is it at the moment? Half a year or a few years?" "…According to the Valkyrie on your side…it'll be a few thousand years at the least, or perhaps ten thousand years. That's how difficult it is to bring down that strengthened Trihexa. Even the God of the Bible expended all of his power to seal it away." …Ten thousand years…. …We might not even be able to see each other for a year…! There were still so many things that I wanted to talk about with sensei. I also wanted to hear more of his advice…! It'll take ten thousand years…how can that be!?

"...All of that, how, how can it be. It'll need…s-several thousand years, or even ten thousand years…." In my heart, I wanted to release all of that anger, grief, and sadness, but I was unable to, and a variety of emotions swirled around in my chest and mind. How could Vali remain so calm while thinking of all these things when I realized something was extraordinary? His voice was also trembling. "...Yeah. I really can't stand him. …He always says and does whatever he wants selfishly. …He's taught us so much, so going off on his own…." Seeing this unexpected reaction from my rival, I involuntarily began to shed tears. …Damn you, don't let me see you with a response like that now…! It's too horrible…! Usually, when we were in situations such as these, sensei would call out as he arrived and then start making jokes. But no matter how long we waited, sensei still didn't show up in the patient room. Vali said to me.

"…Azazel said to you that you were his last and best student…" ...…. ...You're too mean sensei…. I couldn't hold back the tears welling up, and I began to sob. I recalled all sorts of encounters, training sessions, times when I fought against powerful enemies, and the times when we were in Kyoto and the Vampire's country; all of the places that we traveled to together emerged within my mind as if coming through a set of revolving doors…. …I defeated Apophis…. What would sensei say to me usually…? Ophis held my hand.

"…I'm still here. Regardless of whether it's one thousand years or ten thousand years, I will stay by Ise's and Vali's side." "Then, Lilith also wants to be together." Lilith also took hold of my hand and Ophis' hand. …So these are the so-called people we gain when others are lost, huh? Vali sighed "…It will be a very long time. But, both you and I have bodies that will somehow be able to survive that length of time. For when he returns." Vali suddenly looked out the window, and his voice trembled even more. "At the very least, we must complain to him again." "Yeah." What awaited me from here on was a world without Sirzechs-sama and Azazel-sensei. It will be a long time compared to the time spent together with them, in this world that was now without them. If we had the power and the determination to defeat the 'enemy' sooner, perhaps we would not have arrived at such an outcome…. For the seventeen-year-old I, it was the first time in my life that I experienced such intense tragedy and regret. With this battle as a turning point, a decisive change occurred in the minds of the Two Heavenly Dragons. The thought of protecting something was born within Vali, and as for me, the determination to constantly destroy the 'enemy' was carried within me. Indeed, if I didn't possess that resolve, then someone would disappear. If that's the case, then I should.

Next Day At The Sitri Hospital

As Issei wakes up and looks around to see his mother fast asleep next to him in a chair, she is called Miki Hyoudou.

"Hey mum, wake up," Issei says while tapping her shoulder.

"Five more minutes..., huh wait a minute Issei!" Miki shouted in happiness.

"Hey mum, how are you? Ugh.." Issei says while getting a hug tackled by his mother.

"My baby boy, you had us all worried as you been asleep for ages. I hope you weren't dreaming something perverted," Miki says, then squints her eyes at him.

"No, mum, I am fine. I woke up yesturday, and Vali also caught me up on what happened. Ophis and Lilith were here too, which was nice," Issei says to help calm his mother down.

"Hold on, Issei, Gorou, come in here now!" shouted Miki.

Suddenly they heard footsteps enter the room in the form of a man slightly like Issei but older and has glasses.

"Miki, what happened hun….., Issei?" Gorou was saying until he saw Issei awake.

"Hey, dad," Issei says as he rubs the back of his head.

Soon as Gorou heard that voice, he started to cry, sad tears but happy tears, knowing Issei was ok.

(" Hey partner, it's nice to see your family coming to see you after coming back a hero") Ddraig says with pride

"Yeah, it is Ddraig. Speaking of a family, I wonder where ORC is?" Issei says to Ddraig in his thoughts.

"Hey Mom, Dad, where are Rias and the other girls?" Issei asks out of curiosity

"Well, so,n they visited you for the first week you were in here, they decided to stop visiting you. Rias and Akeno used the excuse of having college work and their work on their territories," Gorou said as he looked conflicted, and Miki looked conflicted.

"Okay, but by the sounds of it, that isn't true. Please tell me what's wrong, and I won't be mad at you cause of it," Issei says with a pleading look.

"Well, I know this is going to hurt you a lot, but they have been unfaithful and started seeing other people behind your back," Miki says, tears starting to come down.

"I honestly can't believe we once saw them as our daughters. The only two people that have not cheated on you are Rossweisse and Kuroka," Gorou says as he holds Miki with a hug while looking at Issei.

"Hmm, I see, so basically, they used me as a tool to get what they wanted and pretended to care," Issei said as his hair covered his eye, and his Aura was starting to leak abit in anger.

"I'm sorry, son, but we rather tell you than lie to you after everything you've been through," Gorou says with concern while looking at his son, who can feel his rage building up.

"I am grateful for that mum and dad, but now they have betrayed me, but before I do something rash, I need proof first, and I know the perfect person to help me with it," Issei says as his rage is still there but not getting higher as he was calming down but also connecting to someone with hope.

The silence was in Issei's room as both Issei, and his parents reflected on what had happened. Still, they didn't know that Issei was trying to reach a particular Dragon God for help which worked as suddenly a rip appeared, and out came Vali, Kuroka, and Ophis.

"Hey Issei, Ophis noticed you trying to send her a message but also alerted to some rage in it," Vali said with a look of concern as he could see Issei hiding his eyes with his hair and the Aura was no joke either.

"Hey, Vali, yes, actually, as you tell with this rage, I found something out that has got me angry, but before I go further, I need some proof and hope Ophis can help me out as she can come and go without being noticed," Issei said as Kuroka comes up to Issei to try and calm him down with her senjutsu.

"Please calm down, Ise-chan nya," Kuroka says while using her power on him.

"Thanks Kuroka, it is helping abit, but I think you will be angry with what I'm about to ask, even you, Vali," Issei said while looking up at them.

"Okay, now I'm curious," Vali said while wondering what it was.

"As am I, Ophis, are you able to set up like a feed while showing it here, for example?" Issei asked.

"I can, but why?" Ophis said while tilting her head to the side in a cute manner.

"Well, I need you to show me the girls that are staying with me and what they are currently doing," Issei said as his Aura leaked out again, showing some anger.

"Okay, I will be right back," Ophis said as she disappeared and Lilith appeared after wondering where Ophis disappeared too.

"So how come you checking on the girls, nya," Kuroka asks out of curiosity.

"Well, from what my parents told me, they have betrayed me and started seeing other people behind my backs," Issei says while his parents nod.

"What!!" Shouted Kuroka in shock and anger, while Vali also started leaking some of his Aura.

"How can my sister do that to you and the other girls after everything you have done for them," Kuroka says, showing how angry she is at them.

"Well, that's why I'm asking for Ophis help with this, as I want proof before I do something," Issei said while hugging Kuroka to calm her down.

"I see why now, Issei. What are you planning to do when you find this proof?" Vali asks his rival and friend even though he won't admit it.

"Well, one, I will be removing these evil pieces in me not before getting Ddraig to absorb its power to screw that bitch up so she can't reuse them and then probably training to get used to my dragon body since my body was made from Great Red flesh and Ophis power in a way," Issei says. At the same time, his parents stared in shock as they didn't know about that bit.

"Issei what you mean about Great Red's and Ophis stuff?" asked the confused parents.

"Oh right, you didn't know about that bit. Well, you know how I faced a Maou wanna be called Shalba," Issei says while waiting for a reply.

"Mmm, oh yeah, you thought him to save Ophis, right," Gorou said, remembering that bit.

"Well, before defeating him and saving Ophis, he hit me with an arrow fused with Samuel's blood which he was planning on using on Vali but used it on me as I kicked his ass. After saving Ophis, we entered the dimensional gap and died, but Ddraig and all my senpai are in the boosted gear save my soul, which Great Red and Ophis made me a new body and put my soul into it," Issei explained while looking at shocked parents.

"So you're a full dragon but with evil pieces," Vali said with shocked eyes as well as he didn't know about this bit.

"Pretty much, but like the sacred gear had to get used to the power hence why I can only just use Ophis power side of things imagen what it is like it I'm able to use both of their powers when I train," Issei said as he grinned.

"That would be interesting," Vali said as he grinned at the idea.

"Those bitches are going to regret this as you died and were reborn to save them and the rest of the world as well," Miki said with so much hate that Gorou had to comfort her as he shared the same feeling.

"Well, no more helping them once we get proof as then we will need to get Lord and Lady Gremory as well as Grayfia," Issei said, hatching his plan.

"I will send them a message. Then it is nice for all of them to see this happening in front of them," Vali says as he uses his communication circle to contact Grayfia.

"I know Rias mum is pretty much a full-blown sadist, so her punishment is going to be worth watching if it happens," Issei said while shivering at the thought and everyone else apart from her Vali.

"Ok, Issei, Grayfia, Lord, and Lady Gremory are coming here soon. What are you planning to do if the truth you heard becomes true?" Vali asks again, wanting confirmation.

"Well, I guess I can tell you, since you'll not give up asking, I would eject the evil pieces out of me while absorbing their power so they can't be used again. While doing so will most likely go train somewhere away from them," Issei said nonchalantly.

"But wouldn't that kill you?" Miki says, worried about her son.

"If I was still human, yes, but since Great Red and Ophis gave me a new body with both their powers, I'm more Dragon than even Devil, surprisingly," Issei says to calm his mother down.

"So where would you go to train, son? I don't want to lose you again," Miki asks while Gorou nods in agreement.

"Hm, well, I don't know as of yet might explore Ddraig's home of Wales. His cave should be still there and sealed from human eyes," Issei said with a smile.

"I want to come with you, nya, could even try and teach you some senjutsu nya," Kuroka says while still hugging Issei from the side.

"Would be nice to try might come useful but first, if things are how they seem and I'm not around Vali, Kuroka, can you do me a favor and look after my parents?" Issei asks in hope.

"What you mean if your not around Issei, I don't understand?" Miki questions Issei worriedly.

"I will be happy to help you, Issei, as a rival and friend," Vali says while bowing.

"Me too, nya, since they would be a mother and father-in-law, nya," Kuroka says teasingly.

"Thank you two and answer the question, mum is if I not around due to training or somewhere else, I would rather have you safe from harm's way," Issei said as he turned to her.

"Why would I be in harm's way?" Miki says, confused.

"Think about it, Mrs. Hyoudou. If Rias and the others found out Issei left, they could turn on you to try and force him back or wipe your memories of him, etcetera," Vali said, hoping she understood.

"They would do that? After everything?" Miki says in shock.

"Yes, they are capable, especially how much greed she has in her," Vali states.

"Sorry, mom, dad, if you are still not sure, I can always ask Grayfia and others to hide you or maybe go vacation somewhere?" Issei says as a suggestion.

"Thank you, son, I'm sure we will be ok, but when you take your pieces out, we will take a vacation somewhere, maybe to the United States as we always wanted to explore San Fransico and other places," Gorou says with a smile.

After Gorou says that, the door to the Issei hospital room opens, and Grayfia, Lord, and Lady Gremory enter, see everyone, bow, and then smile when they see Issei is awake.

"Ah, it's nice to see you are awake, Issei, but I'm curious why you asked us here. Is something the matter?" Lord Gremory asked with a worried tone.

"Well, thank you for coming to see me, and yes, we have a situation that requires you to know what is happening. As I was being treated and in a coma after using my Diablos Dragon form, my parents noticed the girls acting weird after they stopped seeing me a week or so afterward. At first, they thought it was like college work or territory work, so they didn't chase it but soon saw them hanging out with other boys and dating them." Issei says as he explains what he has been told.

"What! We have not been told anything about this. Have you got any proof?" Lady Gremory asks, panicking.

"Well, that's what we are doing at this present time. I've asked Ophis to set up some hidden camera footage and see what we find," Issei says, trying to calm Lady Gremory down.

"I still can't believe they would do this after everything you have done. I hope they haven't cause I would punish them for this betrayal to you," Lady Gremory says with abit of anger.

Suddenly Ophis appears through a tear in space, looks at Issei, nods to her achievement, and gets a candy bar as payment and a head pat.

"Ah, perfect timing. Ophis ready when you are if you could," Issei said as he continued to head pat the Dragon God.

Suddenly Ophis moves her hand and shows multiple screens viewing all the girls currently with someone else. The first shows Akeno and Rias in an office room with an older-looking bloke making love and kissing a lot while they were slagging off Issei. Then the screen showed the remainder of the peerage except for Rossweisse, who was away helping around the school and could see them talking about their new boyfriends and saying they were nothing like Issei even his childhood friend Irina was slagging him off. This caused Issei to unleash his aura but not demonic it was pure dragonic, which made all the three dragons in the room gasp as Issei was turning into a pure dragon, and the aura he was giving off was strong as the heavenly dragons, maybe more powerful. But afterward, it stopped, and I heard Issei mutter one word, which would shock everyone in the room.

"Purge," Issei muttered with a bit of anger in his tone.

Suddenly everyone saw all his pawn pieces eject out of his body, but they noticed something different about them. All their power was absorbed and just left them blank and cracked.

"Issei!" Everyone shouted in shock apart from Ophis, who stared in awe with a calm look.

"I'm ok and sorry you had to see that, but Lord & Lady Gremory-sama, I no longer want to marry your daughter due to this act, and also Grayfia, I'm sorry you had to see this, but I still see you as an Older caring sister so please carry on looking after me and my family," Issei said as he looked at them with tears coming down his face.

"Hai, I will, Issei. You'll always be my little brother. I have come to love and cherish, but may I ask what that aura was as it wasn't your demonic aura but more dominant," Grayfia says as she hugs Issei.

("I can answer that for you, Grayfia, that aura was a birth of a new Dragon. It only happens when they either achieve it from over the years or by something horrible to change his views on things") Ddraig says proudly but also sad.

"A new dragon, but how is that possible" Venelana says, shocked with her hand raising her mouth.

"Well, Issei was already a Dragon in theory due to having his body rebuilt by Great Red and Ophis," Vali said, giving them the knowledge in case they didn't know.

"I see, so that's how come you came back into the underworld on top of Great Red that time," Grayfia says as she looks at Issei, who grinned slightly.

"Trust me. I was just as surprised when I woke up on him that time and Ddraig explaining what happened," Issei says as he giggles slightly.

"So what now," Miki asked in confusion.

"Well, Zeoticus and I will punish Rias and her peerage once we get some help from Ajuka and also will be removed from Kouh because of this," Venelana said as she looked angry.

"I will sort that out for you, Venelana-sama, and I will also inform Lady Phenix of Ravel's betrayal," Grayfia says as she bows and leaves through the magic circle.

"What about you, Ise dear?" Venelana asked in worry for her adopted son she grew to like.

"Well, now I know the truth. I'm going to train with my dragonic self now, and knowing this new aura will need to understand it but also I want to gain the knowledge I have now noticed I lack in that department for too long," Issei says as he lowers his head in shame.

"I can help with that," Ophis says as she approaches Issei to hold his hand.

"I am also going to tone down my pervert side as well as I've had enough of being used by that tactic," Issei said in determination. "I'm very sorry I put you through that situation, Ddraig, and Albion."

("It ok partner, as much as it hurts my pride, I grew to understand you more from it, but now that goal has changed, I will help you heal from this pain more so as I never actually shown you my human form have I") Ddraig says smirking at his partner.

["As Ddraig said, it did ruin our reputation abit even though mine was Vali's fault on that point, but I grew to respect you as a fellow dragon and realized how kind and strong-willed you were, which is rare in a dragon these days"] Albion says as he agreed with Ddraig

"Hehe, thank guys," Issei said as he noticed how much love he still has for family and friends.

"Well, Ise dear myself and Zeoticus will depart now and bring you pieces to show Rias the fruits of her actions, so to speak, and remember you are still family to us if ever needed, and also call me by my name from now on," Venelana says as she smiles before kissing Issei on the head before they both disappeared through there own magic circle.

"So Issei ready to go and train," Ophis says, still holding his hand.

"Yeah, I am ready. Vali Kuroka, please look after my family for me, and I will see you soon," Issei said before he disappeared with Ophis.

Timeskip 2 days after

Rias and the rest of the ORC were in the clubroom discussing their new boyfriends and not even bothered by the fact Issei was gone as they never went to see him after the first week. Still, Rias had a call to meet in the clubroom for an appearance of her family, wondering why but they asked if it was to update them about Issei as much as they didn't care since they were more involved with their new boyfriends thinking they got away with it.

"Rias-Onee-chan, do you know why we been called here?" Asia asks while tilting her head.

"Not Asia. I'm guessing it's probably to do with the pervert, even though he has the advantages of being a strong piece. I can't believe I have to marry him after all this," Rias says as she spits it out.

"Ara ara, well, it was fun playing with his feelings. I know he helped us get stronger, but that's the only good thing about it," Akeno says as she holds her hands to her mouth.

"I can't believe my childhood friend turned into such a perverted beast. I thought he would have changed by now after all this amen," Irina says as she moves into a prayer motion.

"Well, none of you will have to worry about that now," Venelana says, surprising the group with guards around them.

"Mother, what's going on? What's with the guards?" Rias asks, shocked as they didn't feel her presence or the guards.

"Well, Rias, all of us have seen what you've been doing since Issei been in the coma and just say he's left you and the group. As for the guards, you all going to be brought back home for punishment and no refusing," Venelana says as she casts an anti-magic spell other them all apart from Rossweisse, who stood next to Venelana.

"What!, Why, mother?" Rias asks while crying.

"Cause I have seen what you did and time for punishment, dear Rias, guards do your job," Venelana said as the guards moved to them and placed them in cuffs before teleporting them away.

"Rossweisse dear, I apologize for you to see this behavior of my dearest daughter," Venelana says.

"It's ok, Venelana-sama, but what of me now, as I'm guessing your stripping Rias of her title and all?" Rossweisse says concerned

"Well, yes, that will happen, but I have spoken to Ajuka and the rest of the council, and due to your help in sealing the beast and other achievements, you have been promoted to High-class devil and will have your pieces if you so have it," Venelana says with pride.

"I would be happy to accept, but what about the protection of Kuoh and Issei?" Rosswiesse asks.

"Well, Kuoh will be under yours and Sona's protection for the time being, but about Issei, sadly, he purged his pieces as soon as he saw what the girls had done, and not only that, he left to train his new body as a dragon," Venelana says with sadness at the end.

"I see. I hope Issei will be ok. I never got to admit to him how much I love him," Rosswiesse says as she blushes at the end.

"Ara ara, I bet Issei be happy to hear that, but I don't know how his heart is now due to the actions of the other girls," Venelana says with concern.

"Well, knowing him, he will get back up on his feet but hide his broken heart under a mask," Rosswiesse says with sadness.

"That is true. He knows how to hide his pain well. Bless him. By the way, I have notified Sona of what Rias and crew have done and just say she is angry with them and is very worried about Issei, which is shocking," Venelana says as she holds back a giggle.

"Sona tends to hide her feelings well, but I know she is concerned as she sees him as another student under her care," Rosswiesse says.

"That is true, by the way, Rosswiesse. Since Kiba and Gasper are innocent unless they knew what happened, I would transfer them to your new peerage if see fit, so you have some sought of help," Venelana says, smiling at the young valkyrie.

"Thank you, Venelana-sama," Rosswiesse said as she bowed.

"No worries, dear, as you are still under Gremory, you are family and will always be once this is sorted. I will inform you of the transfer Ajuka will be here with your new set in a day or so. Issei also asked if you look after his mum and dad while he's away," Venelana says while putting her hand on Rosswiesse shoulder.

"Understood, and if Kiba and Gasper do come under me, I will make sure they move into the house with Issei's parents for extra protection and also build up on training plans.

"Already thinking as a king, I'm glad to see that. I also asked Sona and her peerage to move in there if they wanted and been told about the situation, but it is hush-hush," Venelana says.

"Understood. I will get on with my work now then, Venelana-sama, and hope things turn out ok," Rosswiesse says, bowing again.

"I'm sure it will well keep in touch, dear," Venelana says as she disappears through her magic circle.

"Oh, Ise, please be ok and hope you return safe and sound. That way, I can express my feelings for you," Rosswiesse thought.

In a cave in Wales

"So we figured out my Aura, and slowly progressing with it, should we now focus on knowledge as that's one area I must improve on," Issei says to Ddraig and Ophis, who are there training him.

"That is easy, Issei. With a simple tap of my finger on your forehead, I can send you my knowledge but be warned, it is painful," Ophis said as she walked up to him.

"Well, nothing new there for me. Should be used to pain by now, haha," Issei says as he joked.

("Partner, as much as it pains me to hear that you shouldn't let it carry one") Ddraig says, trying to cheer him up.

"I know, Ddraig, but my shock was seeing your human form in my mindscape. I should have realized you were a female from the way you acted when I was obsessed with Oppai," Issei said as he palm-faced himself.

("Well, I did. It'll surprise you, and for now on, you have me to cheer you up as long as no perverted stuff") Ddraig says just to tease him.

"Haha, I know, I know," Issei said as he laughed.

"Okay, Issei gets ready. This might hurt abit," Ophis said as she touched his head, sending knowledge into him.

"Oh my god! This hurts way more than the light spears!" Issei shouted as bearing with the pain.

"There, that should be enough," Ophis says as she puts her finger down from Issei's head and tilts hers.

"Wow, even though that hurt but wow, so much knowledge of everything, thanks Ophis, with this knowledge, I will be able to come up with even more ideas from using my new powers," Issei says as he grins.

"You're welcome, but you still have plenty of training to do can use the time magic to make you have a year's worth of training within a couple of days," Ophis says, preparing him for more training.

"Sounds good. Let's get to work then," Issei says as he puts his fist in the air.
