Chapter 21 R-18+

"This can't be good" Ddraig said ominously.

"Yeah" Issei replied and it was confirmed when Yumi and Karlamine appeared in front of him. Both girls were soaking wet and Yumi was clearly upset about something.

Yumi looked up and noticed the young man and jumped onto the bed, "Issei" Yumi cried out despite being soaking wet.

"What happened Yumi?" Issei said nervously. Yumi was never this emotional and that meant something major happened.

"She had a long night and could use a friend" Karlamine replied.

Issei didn't say anything else but simply wrapped his arms around Yumi willing his boner away for the moment and hoping everything else would take care of itself.

"There there, just cry for now. You can tell me what's going on after you're done." Issei said calmly.

"I'll leave this to you." Karlamine said with a smile on her face.

"Got it" Issei replied as he held a tearful Yumi close while Karlamine left the two to chat.

(Scene Skip)

It took around ten minutes for Yumi to stop crying and when the tears were finally over, Yumi realized that she was on top of Issei while being soaking wet, "Sorry about that. Let me get up for a second to get changed" Yumi said bashfully forcing herself off Issei so she could get out of her wet clothes.

"You're just fine. So tell me what happened" Issei shrugged as he took the chance to get out of his own wet clothes changing into a pair of boxers before getting back on the bed.

Yumi soon followed, snuggling into the right side Issei's body in an ice blue bra and panty set.

Issei's warmth helped Yumi to calm down particularly since the conversation to come would be difficult but she had to do it since Issei was already aware that something happened.

"Have you ever wondered why I always wore a male uniform Issei? Well before you got involved?"

"Yes I have, especially when you have a body like this" Issei teased taking the moment to grope Yumi's breasts.

"I'm serious Issei" Yumi replied with a slight pout resisting the urge to moan.

She liked what he was doing but this was business time.

"Fine" Issei smiled settling for simply wrapping his arm around the blonde once again.

The pout on her face turned to a frown as Yumi recalled the worst moments of her life, "Before I met Rias, I was one of one hundred children selected for a project sponsored by the church known as the Holy Sword Project." Yumi revealed catching Issei off guard.

Issei was slightly shocked about the news, "So you were actually an exorcist in training." Issei said in slight disbelief.

"That's right. The Holy Sword Project was supposed to teach me and the other children how to use the Holy Sword Excalibur and I was thrilled to be given the chance to serve God and to use a legendary holy sword." Yumi revealed shuddering slightly when she mentioned God's name.

"You say supposed to, but yet you're here with Rias. What happened?" Issei said nervously making sure to hold Yumi tight because he could tell they were getting to the crux of the story.

Yumi gathered herself since this was the hardest part for her, "For a long time it was difficult, but I endured the harsh experiments. Until we outlived our usefulness" Yumi said coldly.

"No" Issei replied having a good idea of what was to come.

Yumi fought back tears since she had to tell Issei the truth, "That's right. They gathered us all in one room and one by one, all of my friends were slaughtered by the people who had experimented on us. The only reason I'm even alive today is because my twin brother sacrificed himself to allow me to escape. I ran as far as I could, praying that somebody would save me before Rias ultimately found me." Yumi cried out with tears falling down her face.

Issei had no response but to hold her tightly and comfort her, "I see. You wore the male uniform so your brother could experience life even for a little bit."

Yumi was on the verge of tears again since Issei's words hit the mark perfectly.

"That's right. I hated myself for being the only survivor and I hated Excalibur." Yumi cried out.

"That's enough Yumi. You don't have to say anymore" Issei replied calmly stopping her from saying anymore.

He could only imagine how much pain Yumi was in.

"Thank you for hearing my story Issei." Yumi said bashfully as the tears stopped flowing.

"Of course" Issei said calmly before leaning over and kissing her on the cheek.

"Thanks" Yumi replied with a blush before snuggling deeper into Issei's body.

She was well aware that Issei's boner was throbbing beneath her body as they spoke but also aware that Issei wasn't going to act on it yet.

Despite the odd way their relationship started, the fact that Issei could put sex aside for her was worth a lot.

(Scene Skip)

School went by fairly quickly for Issei since he knew that Irina would be waiting for him when he returned and once the bell rang, he went straight home much to the annoyance of Murayama and Katase.

Unfortunately for Issei, any excitement he may have had for Irina's arrival vanished due to Yumi's story and the cold reality of why she was visiting.

Irina's father Touji told him about the various Holy Swords during their training and Excalibur was one that always fascinated Issei because of the fact it was so powerful that it had to be split into seven fragments in order to prevent King Arthur's enemies from using it.

It was obvious that somebody attacked Yumi with a fragment of the blade before she made her impromptu visit with Karlamine.

'Ddraig how much do you wanna bet that whatever business Irina has involves the fragments of the Excalibur' Issei asked mentally as he made his way home.

'That isn't much of a bet partner' Ddraig replied aware of the same thing.

Issei and Ddraig were silent until they arrived at Issei's house at last "Here we go" Issei said calmly opening the door.

His senses picked up three figures sitting in the living room along with two powerful holy aura's and Issei's feeling of dread only grew as he arrived in the room to find his mother sitting with a blue haired girl and his very grown up childhood friend.

"Hey Issei. Long time no see" Irina said happily getting up from her spot on the living room couch and walking over to Issei.

Irina and her partner were wearing a long white robe that covered their bodies and the church's battle suit underneath but Issei couldn't see the latter.

His mother Miki Hyoudou was sitting across from them with a smile on his face.

"It's been a long time Irina" Issei said with a weak smile as he and his childhood friend shared a hug for the first time in a long time.

Irina had become far more beautiful than Issei could've ever imagined and a part of him was drooling with excitement.

The problem was that another part of him was focused on the holy aura he sensed earlier and Yumi's story.

"So this is your childhood friend Irina. He doesn't seem like much." Her partner said bluntly.
