A/n: A little note on Y/n even though he (or she) is all powerful it dosen't really mean they know how to use it she's all powerful not all knowing his still learning on how to use it properly even with the Amulet she has which they got from a maker but that doesn't mean they are to underestimated since he can pretty much destroy universes with snap of a finger anyway just wanted to make sure that is there now to the story.

Y/n Quote: I normally try to hold my tears but when I do cry to me it is not weakness but proof that you are human and you care.

Y/n pov

I was currently looking at the boy clothes of the recently all girls school

A/n: left one.

Y/n:

After telling Murayama's parents I didn't really go to school since my dad wasn't really around they decided to enroll me into the same school Murayama goes to rather quickly too

Murayama: So your coming along or are you going to wait there

Y/n: Coming just got to change.

Timeskip

We had finally arrived at the school as we walked by other students

Girl 1: Who is he?

Girl 2: His so handsome!

Girl 3: Is he a new prince?

Girl 4: Is that Murayama maybe she's showing him around.

Boy 1: Damnit another pretty boy.

Boy 2: Is it just me or does that guy seem pretty innocent minded.

Boy 3: For some reason that guy looks extremely intelligent.

Boy 4: I've just seen and I like him not in a gay way though.

Griffon [In Mind]: Look Y/n people are already talking about you.

Y/n: I don't like it.

We had continued walking as a voice called out

???: So your the new student.

I had turned to see a girl with black hair glasses

Murayama: Student Council President Sona Shitori.

Sona: Thank you for introduction I'll handle the rest you may go to class.

Murayama nods as she goes to her class as I look at Sona and smile

Sona pov

I had been sensing a very large demonic power for a few days but couldn't track it because it was like it was covering all over the place but soon found it's source to be the new student that was standing in front of me

Sona: So what is a powerful devil like you doing here?

Y/n: Going to school.

Sona: Not what I mean and actually I've never even heard of you before until today.

Y/n: I like to stay hidden

Sona: I highly doubt that since your not even bothering to hide your presence.

Y/n: Can track it to an area but not the person.

Sona Thoughts: He does have point about that.

Sona: But seriously what are you doing here?

Y/n: Going to school.

Sona: That's it?

Y/n: Yes so are going give me my schedule or do I need to fake an accident?

Immediately I felt an increase in demonic power

Sona Thoughts: His power just skyrocketed how powerful is he?!

Sona: Uh y...yes here...

I handed him his schedule as he smiled and took it

Y/n: Thanks and by the way this conversation never happened unless you want two bullet holes to replace your eyes.

He left with his power still at the height it was set to I gulped as I didn't want to get on his bad because he can easily kill me with no problem

Y/n pov

I was walking through the school as I finally made it to the classroom I waited after knocking as the teacher told me to wait after a few the teacher let me in

Teacher: Alright introduce yourself.

Y/n: Hi I'm Y/n L/n and I like to break legs of perverts and kick their crotches like football!

After saying that some of the men seem to stiffen up as I stretched my head wondering why

Teacher: Well then you can sit by Issei Hyoudou Mr. Hyoudou could you please rise your hand.

He did what he was told as I recognized him I then went over to my spot and sat down

Issei: Your that guy from yesterday.

Y/n: Yep and the guy who told the girls your hole spot.

Timeskip

It was the end of class as me and Murayama was going heading towards her alongside us was her friend Katase

Y/n: Nice to meet ya Katase.

Katase: You as well also aren't you the guy that left after we arrived to beat the Perverted Trio

Y/n: Yep how'd you know.

Katase: Many of The Kendo Club saw you leave.

Y/n: Ah the explains it.

After a little bit I stopped when I saw a girl with Issei

Murayama: Y/n why did you stop?

Katase: Yeah something wrong?

Y/n: Fallen.....

Murayama: Fallen?

Y/n: Hmmmm oh nothing just the girl over there.

Murayama: Oh yeah Issei must have bribed her.

Katase: No doubt was blackmailed by him!

Y/n: She may be acting but isn't acting like that.

Murayama and Katase: Huh!?

Y/n: She has a sinister aura around her she may be able to hide it with others but she can't hide it from me.

Murayama: Sinister aura....... WAIT you mean she's going to kill Issei!?

Y/n: Yep he may be perverted but he doesn't deserve to die his pretty much innocent in my book.

Katase: Well if put like that.....

Y/n: And who knows maybe what will happen will cause him to change.

Timeskip

We had started following Issei and the girl as we were in a restaurant

Katase: I feel so bad for her.

Murayama: Yeah.

Y/n: Just stay quiet we don't want spook em.

We watched Issei it was sort of funny

Y/n Thoughts: Suffer more bitches hehehehehehe.

Griffon [In Mind]: Oh boy Demon Y/n is coming out better lock your doors at night people when this psycho is out and about.

I then shook my head as the thoughts of murder and anarchy were shoved with my darker self back into the deepest parts of my mind

Timeskip no pov

Our heroes had been following the couple for a few hours which was starting to get painful to watch well except Y/n which his demon half actually enjoying it quite a bit anyway they were at the park as Y/n and his new female friends were watching Issei and his fake girlfriend they were in front of a water fountain as the girl looked at Issei

Fallen Girl: Can I ask you a question in honor of our first date there's something I'd like you to do.

Issei: Sure you can ask anything at all.

Fallen Girl: Would you die for me?

Y/n Thoughts: Welp seems to be my cue to step in.

Y/n pulled out Diablos and walked out the bushes where he and Murayama and Katase were hiding

Issei: I'm not sure if I heard you right could you repeat that.

Fallen Girl: I said would you die for me.

Then the girl turned transforming into her real form

Y/n stood to the side aiming his gun at the angel but she formed a spear made of red light and threw it at Issei but before he was hit Y/n shot the spear destroying it and blasting a hole in a nearby tree

Y/n: Not so fast little crow.

Issei: Y/n?!

Y/n: Hey Issei how's yo..

Y/n didn't get to finish as he immediately spat out a large amount of blood Y/n looked down to see a red spear of light through his chest and looked up back at the angel with a bored expression as he then shot one her wings off

Y/n: Really...... did you really think that would have done something?

???: Maybe not but getting rid of these two might.

Y/n turned around to see Murayama and Katase stabbed through the stomach area as suddenly Y/n couldn't feel his arm as looked to see it was gone as blood rushed out of the wound Y/n found it to be flung over to Murayama and Katase Y/n was about to pull out Angela but a spear of light through his head and there was enough force to pin him into a tree

Y/n: Ooooowwwww.

Y/n then pulled himself off the tree as his arm grew back which he used to grabbed the spear of light Griffon came out as Y/n looked at the spear as Y/n did something to it as darkness and light covered the spear after a few seconds they went away as Y/n had now created his own spear of light

Y/n: Now then let's check on the others.

Y/n went over to Issei as Griffon went over to Murayama and Katase Y/n found Issei to be already dead as Y/n then revived him

Griffon: Huh Y/n you might want to see this!

Y/n then went over Griffon to see Murayama and Katase already healed

Y/n: What in the hell?

Griffon: Yeah exactly what I thought.

Y/n then placed his hand on top of Murayama's head as he felt demonic power within Murayama he then widened his eyes as he then placed hand Katase's head as he felt angelic Y/n then got up and looked around and saw his severed hand which he walked over to as he reached it he picked it up to find it was completely drained of blood

Y/n: Holy shit!

Griffon: What is it?!

Y/n's severed hand became dust as he looked at Katase and Murayama as they now were an angelic and demonic beings Katase within a body angel and Murayama in a demon's but thier minds were still human

A/n: And done also here you go

Murayama: When Y/n's arm was cut his Nephalem blood come out of it but his demonic half of his power split from his angelic half causing his blood to turn black and not only that his blood mixed with Murayama's as it caused it to react as Y/n's demonic power found Murayama to be a proper host as it entered Murayama's body thus turning her into a demon in body but not in mind

Demon hand: Left Hand: Murayama can call forth Y/n's demonic power in the form of a demon hand

Powers:

Demonic Force Manipulation: The user of this power possesses and is able to utilize strong demonic power. This ability not only grants the user great strength and control over numerous variations of demonic abilities but also allows them to overwhelm weaker demons as well as rival that of powerful demonic entities.

Katase: Like Murayama Y/n's angelic power split from it's conter part thus causing his blood to have angelic blue haze to come from it and just like Murayama Y/n's angelic power found Katase as a proper host thus turning her body into that of an angel's

Angel Hand: Right Hand: Like Murayama Katase can call forth Y/n's angelic power in a form an angelic hand

Powers:

Angelic Force Manipulation: The user of this power possesses and is able to use strong angelic power. This ability not only grants the user great strength, abilities, and control over numerous variations of holy energies, but also allows them to overwhelm weaker angels as well as rival that of powerful sacred entities.

Both: Both Murayama and Katase have a connection to Y/n since they are using his power which was accidental given to them but this comes with perks as they can travel from universe to universe and etc like Y/n
