what the hell am I?

The devil

Deku is keeping an eye on the girl and hasn't spotted the creep

Deku:you see anything?

?:no.

Deku:good. Hey can you make anything?

?:yes with my mimicry.

Deku:how bout you make a high powered rifle.

?:easy.

Deku:okay. Oh by the way I gave you a name.

?:and what would that be?

Deku:diablo.

Diablo:I like it.

Deku:good. Wait I see someone.

Diablo looks at what deku is pointing

Diablo:we should "ask him to leave her alone".

Deku:yeah. Phantom.

Meanwhile on the ground

The creep is hiding behind a wall and panting and has a smile that would make the devil creeped out

Creep:mine mine mine. She will love me. Even if I have to force her.

All of a sudden he's grabbed by the throat and against the wall and sees a tall black figure

Phantom:I know what you're doing and I'm telling you this once. Stop. Or I will kill you.

Creep:okay I will I will.

Phantom:Alright. Goodbye.

Deku leaves and keeps an eye on mina

With mina

Mina:"I hope he's still around. Wait what was that."

She heard someone on the roof of the building to her right

Mina:hello?

Deku pokes his head from the side and smiles down at mina

Mina:can you come down?

Deku:yeah in a sec.

He jumps off the roof but his legs turn black as he lands then after a few seconds turns back to normal

Mina:hey did you deal with him?

Deku:yeah. Well kinda.

Mina begins to worry

Deku:I may have threatened him.

Mina:what?

Deku:yeah not my best moment.

He rubs the back of his neck

Mina:hey do you mind staying with me until I get home. My parents come back in an hour.

Deku:got it. Just let me change my clothes.

He morphs his clothes to pretend to be a friend of mina's from school

Creep:just great how many friends does she have now that's two. How many? Dosen't matter

With deku and mina

Deku:he's not in sight. You should make a run for it.

Mina:I still don't think he's gone.

Deku:that's cause he's not.

She look at him with a worried expression

Deku:one sec.

Deku cuts of his finger and before mina can freak out he grows a new one and the finger he cut of turns into a black puddle

Mina:explain.

Deku:later. This will attach to you and keep you safe.

But before he can explain further he sees the creep from earlier holding mina and he puts a knife to her throat

Creep:me and my darling are going to leave and you won't follow or she gets her throat slit.

Deku:I don't need to do anything.

A black tendril pops out of mina's back and grabs the knife and mina turns around and throws him to deku who then sends him into a wall like a few meters

Mina:thanks.

Deku:yeah no problem. I might just kill him.

Mina:don't.

Deku walks to the guy

Deku:you sir are lucky. Because of that girl your not 6 feet under. To be honest you may be scared of me but I've haven't seen enough of what she can do and I'm terrified. Count on the fact that your not dead.

He then walks back to mina who heard nothing then they walk off eventually they give each other their numbers then they say goodbye

Mina:he was super nice I hope he goes to U.A.
