~~ POV Tetsuya ~~

When I woke up, I feel many injuries and broken bones while I lay on the ground. And in front of me, there is Kokabiel who wears a shocked expression on his face while distracted by the Barrier that is broken into pieces.

As I look for surrounding, there is something wrong with my eyes as I can see many lines across Kokabiel body and also my surrounding.

What are these lines that my eyes show me? At that time I couldn't care less at what my eyes show me since the things that happen inside my mind are too busy at wanting to kill Kokabiel and also feeling the pain of my body that I suffer from Kokabiel. Somehow my minds tell me to cut the lines that show from Kokabiel's body in my eyes.

In a split second, I then cut the lines that show in Kokabiel's right hand that held a dark color light sword with my Gram (Reforged).

Kokabiel then screams in pain as he lost his right arm while looking at me with a confused expression wondering what happens to his right arm.

I then use 'status recovery' while using Gram (Reforged) to stand on my feet due to the damage that I receive from that Kokaballs. My body instantly healed and my fatigue is also gone as I can feel all the damage I receive has gone.

My wound has already healed as I checked all part of my body that gets hit by Kokabiel attack and looks like I also obtain some jackpot as I can see some lines that surround me, I can't believe it, I by some chance obtain the 'Mystic Eyes of Death Perception'.

{A/N: typemoon.fandom.com/wiki/Mystic_Eyes_of_Death_Perception}

Hmm... There is someone who destroyed the barrier, Is it Mom? Well probably can't be Shuri-san since her strength isn't enough to destroy the barrier probably... Well maybe she can if somehow my mom left something to Shuri-san so she can't protect herself. Well, either Mom notices something is wrong or Shuri-san manages to destroy the barrier with something that related to something that my mom left to Shuri-san.

Well looks like both of my personality has been fused together I guess, I can feel something inside of me has changed. I also get a new notification, it seems to make me stronger and I can feel something is different, but I will get to it later after defeating Kokabiel.

Anyway looks like Kokabiel asking me some question to me why can't he regenerate his arm anymore, well too bad he already lose his right arm permanently the time when I cut his right arm with my 'Mystic Eyes of Death Perception', well I'm going to hide this fact since he probably can guess the cause of his regenerate stop once I tell him this.

~~ END OF POV ~~

"What?! Why my arm cannot regenerate? This isn't happening. What did you do?!" Said Kokabiel with a scared expression while looking at Tetsuya.

"Who cares about that, the only things that you need to know is that you are going to die." Said Tetsuya while looking at Kokabiel with a neutral expression.

Kokabiel then realizes that the wound he causes to Tetsuya is already healed, and this makes him more scared of Tetsuya. This makes Kokabiel wonder about Tetsuya's ability as he thought at first that the ability that Tetsuya had is an item that can fully heal people probably.

Tetsuya then sticks his 'Gram (Reforged)' on the ground and then summons his Incursio in his right-hand.

"Incursio, if you have more power inside your sleeve give it to me, All of it!!" Said Tetsuya while attempt to take all of Incursio power with a serious expression.

"INCURSIOOOO!!!" Shout Tetsuya.

Tetsuya then uses his Incursio while at the same time use his 'Red Vermillion Oni' form, but something happens to his Incursio as it starting to mix with the demonic energy that is burst from his body while he is transforming into 'Red Vermillion Oni'. The inner danger beast Tyrant that reside in Incursio started to mix with the power that Tetsuya let out as it starting to somewhat evolve more and more after it is absorbing the demonic energy that Tetsuya let out during the transformation. Tetsuya can feel that something is changing inside his body as all of his human body parts started to feel the changes too.

But when he undergoes the transformation, he can feel a life force started emerges in his consciousness as it trying to take control of Tetsuya body. Tetsuya already knows that this will happen once he will try to force evolved Incursio, so he only smiles as he suddenly summons a knife in his left hand. The knife that he summons is a knife from a sub-skill that is from Gram (Reforged), that he can use anytime when he equips Gram (Reforged) in his equipment. He then uses 'Mystic Eyes of Death Perception' to locate the life force of Tyrant on his body and then stab it.

"You're 1 minute too early to try to steal my body because I don't have 'Mystic Eyes of Death Perception' at that time, but now you are too late." Said Tetsuya while showing a smirk on his face.

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

[The Item [Incursio] has been destroyed due to the host of the system fused with the Teigu [Incursio]]

[Because of the Host of the system fused with [Incursio]. The host race will be changed into 'True Demonic Oni God - Dragon - Human Hybrid']

[You have obtained a new title called [Are you still a human?! or a Dragon?!]]

[You have obtained a new skill called [Neuntote]]

[You have obtained a new skill called [Invisibility]]

[You have obtained a new skill called [Adaptbility]]

[You have obtained a new skill called [Scales of the Tyrant]]

[You have obtained a new skill called [Fire Resistance]]

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

Suddenly a gush of energy inside Tetsuya burst from Tetsuya's body as he also can feel that the life force of Tyrant is gone completely as he pulls the knife off from his body only to show red energy flowing from his knife and then evaporate into the air and there is no wound in the place where he stabbed his knife. He then completes his transformation as he covers with demonic energy.

Right now, the armor and all of Tetsuya body have fused together as it transforms Tetsuya all body part into dragon scales as it covers all of his body, his helmet that fused with him makes his entire head looks like the head of a dragon but with the size of a human head as his face started to transform into dragon-like. On the top of his head, there are 4 horns, 2 of the 4 horns is the horn of the 'Red Vermillion Oni' and the other 2 is the horn of the Incursio itself that grows longer than before evolved. His armor that fused with his body started to give an appearance of Incursio final evolved form (In the manga). Both of Tetsuya eyes change into cross slit pupil that is fused with the 'Mystic Eyes of Death Perception'. He also grows a big wing from his back. The only thing in common is that all part of the fused is adjusting to the body of 5 years old and all of his scales has the color of Vermillion.

'Damn, what a long-ass race name... Wait why is there a word 'God' on my race and what is up with my weird new title?! Did I turn my race into True-God after I woke up?' think Tetsuya who already finish his transformation and see all of his newer notifications.

'Anyway looks like I need to buy 'Dragon Blood Manipulation' from the [SHOP] system since I cannot turn my body back into human form right now. But oh well, on the bright side, I obtain great strength from this transformation, obtain many new skill, and also my body right now is kinda cool, well not trying to be narcissistic here... Oh, I also can fly.' think Tetsuya while also looking at his body with an impressed expression and then looked back at Kokabiel.

On the other side, Kokabiel who sees this now shows a feared expression as he can see that the person he fights in front of him is different than the one he fought before. He can see that he now at a disadvantage as he already cannot regenerate his lost arm, and also the barrier is already broken. Even if he obtains a lot of power boost from the liquid he drank, he will be in a lot of trouble if he doesn't escape right now since he doesn't want to risk it to fight Tetsuya when there is a chance someone that he hated so much catches him.

{A/N: OST: Kajiura Yuki - M40 (youtube.com/watch?v=lgYujuM7KMI) (You can use other music if you want since this is my preference. Anyway, for anyone who didn't know what OST is this, this is Kara no Kyoukai OST }

Kokabiel then flies away from Tetsuya at his maximum speed.

Tetsuya who sees Kokabiel ran away then holds his 'Gram (Reforged)' with his right hand and tries to dash toward Kokabiel while trying to flap his new wings. When he flaps his new wings, he didn't expect that the wings can produce enormous winds that strongly boost his speed as he instantly catches up with Kokabiel.

Kokabiel is shocked when he can see Tetsuya instantly catch up with him as Tetsuya is trying to slash Kokabiel with his 'Gram (Reforged)'.

Kokabiel then turns back and tries to block Tetsuya 'Gram (Reforged)' with his dark color light sword that he summons in his left hand.

But when Kokabiel try to block Tetsuya 'Gram (Reforged)', his left arm in an instant get cut along with the dark color light sword that he summons on his left hand as he can see that Tetsuya is the one who slashes his arm and dark color light sword.

"Arghhh--" Kokabiel who scream in painful get interrupted by Tetsuya as Tetsuya suddenly let out a kick on his face that force Kokabiel falls toward the ground.

"Can you stop your screaming? Your voice is too damn annoying to hear at." Said Tetsuya while looking at Kokabiel who already crash into the ground.

"DIE!!" Shout Kokabiel who is gritting in pain as he summons 15 dark color light spears in the mid-air and launches them at Tetsuya who is still in the sky while flying with his wings.

Tetsuya who see 15 dark color light spears rush toward him only let out a smirk and rush toward Kokabiel with the intention to slash all of the dark color light spear.

Tetsuya in an instant cut through all of the 15 dark color light spears with his 'Mystic Eyes of Death Perception'.

Tetsuya then reappears in front of Kokabiel as he started to cut Kokabiel piece by piece with 'Gram (Reforged)'.

Kokabiel who didn't have time to react is getting slash by Tetsuya from his leg, stomach, neck, and many more as he slowly turned into pieces. Many drops of blood are found splattering around Kokabiel's body after Tetsuya finish cutting him into pieces.

Tetsuya then splashes the remaining blood that stains at his 'Gram (Reforged)' to the ground.

{A/N: OST END}

Tetsuya then looks at Kokabiel who already turn into pieces of meat.

"Isn't this overkill?" asks Tetsuya to himself with a wry smile on his face.
