"Bring it on C*ck shit!!" Shout Tetsuya who right now pointed his Gram (Reforged) toward Kokabiel.

Kokabiel who hears this has veins started shows on his head.

"That mouth of yours reminds me of that wicked woman and that makes me want to tear you into pieces." Said Kokabiel with a scary face while there is some veins show on his head and also his eyes full of blood rage while looking at Tetsuya with an angry tone of voice.

"Then try it, c*ck bas--" Before Tetsuya finish his sentence, he then saw Kokabiel vanish from his place.

Kokabiel suddenly appears behind Tetsuya while holding a yellow color light sword and is about to attack him.

Tetsuya is shocked when Kokabiel appears behind him, he then uses 300 mana to enhance his body so that he can react to the attack.

Kokabiel then attacks Tetsuya with his yellow color light sword. But to Kokabiel's surprise, Tetsuya is able to block Kokabiel's attack with his Gram (Reforged) but he barely only able to block Kokabiel's attack due to his body enhancing and also his sword mastery that makes him be able to react instinctively to Kokabiel attack and block it with his Gram (Reforged).

But because he receives the impact of Kokabiel attack, he then is blown 5 meters away from the place he was standing. But after Tetsuya is blown by Kokabiel attack, he attacks Kokabiel with several 'Fire Bolt' that engulfed with demonic energy while in the mid-air.

Kokabiel who sees Tetsuya's sudden attack decides to defend with his black wings. The 'Fire Bolt' that hits Kokabiel's black wings causes an explosion around Kokabiel.

Tetsuya who is blown away by Kokabiel attack landed safely after he gives a sudden attack toward Kokabiel.

'Damn, his attack is so strong and fast, if I hadn't blocked that attack, I would be seriously in danger right now.' think Tetsuya with a serious expression while both of his arms trembling because of the impact of Kokabiel attack.

Suddenly the smoke that is covering Kokabiel due to Tetsuya's' Fire Bolt' is gone and right now Kokabiel is standing toward Tetsuya with his black wing that is barely scratch by Tetsuya 'Fire Bolt'.

'Tch, his defensive also strong.' think Tetsuya with an irritated expression while looking toward Kokabiel.

"Hahaha... I didn't expect you to survive my attack, well let's see if you can handle more of my attack." Said Kokabiel while looking at Tetsuya with an amused expression.

Kokabiel then dashes toward Tetsuya with immense speed while holding a yellow color light sword.

Tetsuya already expects that Kokabiel is going to attack, so he uses 1000 mana to 'enhance' both of his hands and legs, and try to block Kokabiel with his Gram (Reforged).

Both of their weapons collide with each other. Both of them then exchange many blows from their weapon causing some shockwave around them.

"Not bad kid looks like you can handle my attack right now, looks like I have to get a little bit serious." Said Kokabiel who started to put immense strength on his hand while holding his yellow color light sword.

Tetsuya who feels that Kokabiel just let out immense strength from the collide swords feels that he can be blown far away by Kokabiel's attack right now.

And his guess was right, suddenly Kokabiel yellow color light sword grows larger that Tetsuya who holding Gram (Reforged) cannot withstand such power, and makes Tetsuya blown away by one of Kokabiel attack.

Tetsuya then is blown away until he is stopped by a tree around the shrine, and thankfully his Incursio armor protects him from the impact he gets when crashing the tree.

"Aghhh!!" Tetsuya who is stopped by a tree vomited some blood due to the impact of Kokabiel attack and also when Tetsuya crash the tree by his back body.

"Damn it!! If there is someone who writes this world story, could you nerf the heck outta Kokabiel?" Said Tetsuya with an irritated smile while trying to get up on his feet after crashing the tree.

{A/N: Nope, just go back to fighting. If not, you're really going to die. And also please refrain from calling me cause I trying to fix the 4th wall that you just break.}

Tetsuya then goes back to standing while looking at his HP and Mana.

-------------------------------

HP : 37.300/42.000

Mana : 22.700/25.000

-------------------------------

"Even if I use Incursio I get a lot of damage when I receive his attack, What should I do?" Said Tetsuya who is still trying to think of a way to fight Kokabiel, but suddenly he remembers something that his dad says in the past when he still trying to control his demon blood.

~~ FLASHBACK 1 year ago ~~

-Somewhere in the Training room-

"Tetsuya." Said Yukio while looking at his son Tetsuya who is getting ready to start his training to control demon energy.

"Yes, dad?" Said Tetsuya while looking at his father.

"If you already master at controlling the demon energy, there is something that you shouldn't try unless you already master at controlling your demon blood. Well, I will teach you how to control demon blood after you reach 6 years old, but right now, what we need is for you to control your inversion impulse by controlling your demon energy." Said Yukio while looking at Tetsuya with a proud expression.

Tetsuya who heard this could only smile wryly due to his reward when completing the mission is 'Demon-Blood Manipulation'.

Yukio suddenly turns himself into 'Crimson Red Vermillion' form where his hair turns red and the air around him is so hot.

"As you can see, this is what you can achieve after you can control your 'Demon Energy', well you, still need to learn on how to control 'Demon Energy' if you want to use this form if not there is a chance that you fall into Inversion impulse." Said Yukio while looking at Tetsuya.

Tetsuya just responds by nodded at his father.

"But there is another form beyond this, and this could only be achieved by controlling your inner blood demon." Said Yukio while looking at Tetsuya.

When Tetsuya hears this, he gets shocked by the fact there is another form to 'Crimson Red Vermillion' since he only knows that mixed-blood can only transform into 'Crimson Red Vermillion' in canon.

"Look carefully Tetsuya, because I will turn into a form beyond 'Crimson Red Vermillion'."

Tetsuya only nodded and gulped while looking at his father.

His Father then shows the form beyond 'Crimson Red Vermillion'.

"This is the form beyond 'Crimson Red Vermillion', well your personality will be changed a little bit after turn into this form due to our demon blood." Said Yukio while looking at Tetsuya.

"Then dad what is the name of that form?" asks Tetsuya who is intrigued with the new form that his father shows.

"This is--"

~~ END OF FLASHBACK ~~

'Yeah, that right! 'Red vermillion Oni', if I can transform into that form then I could beat this C*ck bastard' think Tetsuya with a slight smile on his face while looking at Kokabiel who is walking toward him slowly.

"Look's like this is the end." Said Kokabiel who summons a large yellow color light spear in the mid-air, and then throws it to Tetsuya.

"Looks like I have no choice but to transform into that form, even though this is my first-time ever-transforming into that form, but at least I got a general explanation on how to transform into 'Red Vermillion Oni' from dad."Tetsuya then pours 3.000 of his mana into putting a 'barrier' around him, so he can protect himself from the light spear for a while. He then gathers all of the heat known as demon energy around him that scatter around him to the inside of his body while he still in his 'Crimson Red Vermillion' form.

The large light spear then crashes toward Tetsuya barrier, but still not enough to broke Tetsuya barrier.

"It's useless you know!!" Shout Kokabiel who sees Tetsuya summon a barrier then summon 2 more large yellow color light spears on both of his hands and then throw the spear toward Tetsuya.

Both large light spear then crashes toward Tetsuya barrier joining the one that Kokabiel already summon.

Tetsuya who is inside his barrier closed his eyes while spreading all of his demon energy on his body and then increase his demon blood by using his 'Demon-Blood Manipulation'. Right now, he can feel the change that happens inside of his body. His skin slowly turns into a pale color, his head slowly grows two horns on his forehead, his nail slowly changes sharper, and his eyes pupil slowly changes into a slit, but there is no difference in the eye color.

"Arghhhh!!!" Tetsuya who can feel the sound of cracking on his body, screams in pain as he can pass out anytime, but he chooses to endure it because he got a feeling that there is a chance he will die instantly if he cannot endure it.

The barrier slowly cracks as the 3 large light spears trying to pierce it.

The Incursio armor also tries to adjust to the new changes that happen to Tetsuya's body, for example, his horn and other stuff. Incursio appearance then slowly change from his helmet slowly grows another 2 horns from the upfront to adjust with Tetsuya demon horns.

The barrier then crumbles into pieces as 3 large light spears are about to hit Tetsuya.

『Muramasa Art Moon Reflection』In a split second Tetsuya opens his eyes and reflects the 3 large light spears by using one slash of his Gram (Reforged) that engulfed with his mana toward Kokabiel.

Kokabiel who saw this is shocked when suddenly all of his attacks were reflected back by Tetsuya to him.

Kokabiel then summons a yellow color light sword to deflect the 3 large light spears that are coming towards him.

"What?! The spear is 2 times stronger compared to when I throw it." Said Kokabiel with a shocked expression and eyes widen open on his face when he deflects one of the large light spears.

Kokabiel then successfully deflects all of the large light spears, but his eyes are wide open while looking at Tetsuya with a shocked expression.

"*phew* That was painful as hell, thankfully I'm able to withstand it." Said Tetsuya who is relieved he is able to transform safely

'So this is 'Red Vermillion Oni' form.' think Tetsuya who can feel the demonic energy is stronger than his usual demonic energy.

Suddenly a notification pop up in front of him.

-------------------------------

[You have discovered a hidden trait of your 'Half-Demon' race, due to that your race will be changed into 'Half-Human/Half-True Demon']

-------------------------------

'Ohh it looks like I obtain 2 new systems [WORLD DUNGEON] system and [GACH... *ehem*, well, I wonder what kind of dungeon is [WORLD DUNGEON], well I'm going to check it later after this battle. Well, let's see my new title.' think Tetsuya who is going to checks his [TITLE] system but accidentally sees his new systems in his system menu, when he sees the first system he is happy to get a system dungeon where he can gain some level without having to wait for the next mission to appear. But when he saw the next system that is [GACHA] system he decides to ignore it due to past life trauma, well it's not like he will ignore [GACHA] system, he just needs a time where he is in his peaceful and happy state. He then continues to open the [TITLE] system.

-------------------------------

"Looks like it's a jackpot, and it looks like every title I own will activate automatically as long as I fulfill the condition, So technically every title that I own already automatically equip to me. well, it looks like it is different from what I expect where I can only equip one title, as expected from the strongest system from Goddess." Said Tetsuya who is awed with his new title while holding his chin and nodding sagely.

While Tetsuya is enjoying his new title, Kokabiel is looking at Tetsuya with a serious expression.

'There is a change to that kid helmet armor, but more importantly, that kid is getting more and more dangerous while the fight progressed, I need to end this.' think Kokabiel who right now is getting serious and suddenly rush toward Tetsuya with a yellow color light sword on his hand.

Tetsuya who still checking his system and is about to open [STATUS] system, sense that Kokabiel is rushing toward him with his yellow color light sword. he then grips his Gram (Reforged) and rushes toward Kokabiel with his maximum speed.

In an instant, Tetsuya reaches Kokabiel who is rush toward Tetsuya with a yellow color light sword in his hand. Kokabiel who saw this is now shocked by Tetsuya's speed, but to what surprise Tetsuya also surprise at his own speed when he rushes toward Kokabiel.

"Don't bother me when I'm still checking with something important!!" shout Tetsuya arrogantly who then attack Kokabiel with his Gram (Reforge) that engulfed with his demonic energy, and to Tetsuya surprise when he let out the demon energy from his body that turns into a red flame, but somehow he can control the red flame.

Kokabiel who is surprised quickly defends the attack with his black wings before he is hitten by Tetsuya's attack.

'It's hot!!' think Kokabiel with a hurt expression while trying to defend the attack with his black wings from Tetsuya attack that is too hot due to the red flame.

Kokabiel then is blown away toward the forest near the shrine and then is stop by a tree after he already struck down 3 trees that are slowing his impact.

"Ready for the next round?" asks Tetsuya with an arrogant smile on his face while looking at Kokabiel who is stuck in a tree.
