How to accidentally summon a demon

.

A/N: italic is Bakugo's thought but if it is like underlined as well like this then it is Izuku's thoughts that he can read.

Bakugos POV:

This kid! Is this punishment for when I was a human? He got a panick attack so quick he didn't even notice he was indeed at home. His life must be so sad if he's that self deprecating. Well good thing Lamech and I are here. I don't think he knows that I can read his mind but I'll try not to. Is he figeting? I guess I have been quiet for a long time now.

Me: Well, Deku, You did summon me.

His eyes widened as he tried to wrap his brain around what was going on.

Deku: D-D-Deku? So you are li-like them.... I-I-I am sorry to be in your way....

I placed a hand on his head and ruffled it slightly.

Me: Hey, you're not bothering me, I promise. Now can we go to the dining room and you can get some food while I explain what's going on?

Deku: First that would be stealing and I have to go home and second we are actually locked inside here.

I sighed and snapped my fingers, the lights switched on and showed his room.

Deku: *relieved sigh*

Me: Now, as for the door, something is stuck in it and I can get it out but I need you to get ready for school and come get something to eat.

He seemed to be thinking about it before he answered. He looked at me for a few seconds before pointing to the door.

Izuku: What you mean... how?... wait... ready for school?... I am soo confused....

I couldn't help the smirk that made its way onto my face.

Me: Well Midoriya, that book you read is a demonic book, and you summoned me by reading my soulbonding incantation and now we're bound together till you die.

Izuku: Sum...Summoned?!!!!

Me: Yeah you read this outloud and now I'm here.

I showed him the text that had my incantation on it and he sagged, don't tell me he feels like he just burdened me.

Izuku: That gibberish? For real?

I deadpanned and pointed to the cover of the book. "The book of demons" it read.

Izuku: Like that book.... 

I whistled and Lamech opened the door, his black scaleras made his white pupils stand out more.

Me: That's my right hand imp, he is here to help me protect you, now can you please get ready for school? Or I can let him tell your teacher you want the rest of the week off so we can figure this shit out.

Izuku: KYAAAAAAAAAAAAAAAAA THE HECK IS THAT!!!!!

Did he not hear me just explaining who Lamech was?

WHAT THE FLIP!

I know he said right hand... but what?!

IT.... what?! It looks scary.... Especially the white pupils.... Is it alive?!

Oh gosh!

I know what is happening!

I knew it...

I am losing it!

I was tempted to hit him but I was trying to be patient. He's traumatized and being loud isn't going to help. His foster parents are all assholes. And I am going to talk with Lord Lucifer tonight.

Me: Look, Midoriya. I know it's a lot to understand, but you need to breathe, if you want a few minutes to yourself, I can leave and so will Lamech.

Izuku: No... I... is this real?

I looked at his hand and held it, he flinshed but I brought it up to my head and let his fingers touch my horns. He jumped back a little but didn't move his hand.

Izuku: This is definitely real....... Shit..... 

Me: Are you mad? How do you feel?

Izuku: I can't believe this... 

I watched his eyes light up when my tail wrapped itself around my waist. I hid it back away and got up.

Me: Now that you are calm, answer my earlier question, do you want to go to school or do you want us to talk and figure this out?

Izuku: Figure this out. I mean you told me I fucking summoned a demon and then this guy there... What the heck is he or she?

I called over Lamech who sat on my leg and smiled at Midoriya. 

Me: This is Lamech, he's an Imp. Where we're from, which is hell his kind are whatever they want but since he is 'runt' my family bought him and now he's my personal servant, but he's more my son than a servant.

Izuku: And you are a demon... are angels real as well?

Me: Sadly yes, and they're not that nice, they're going to be out to kill you from now on by the way.

Izuku: wait... what?! Am I in danger?! Why would they be after me?!

Me: Because, since our souls are bonded, if you die, I die and angels are trying to kill off demons.

Izuku: Wait if I die you die but what about the other way around? Do I have to be worried about you? I can't even protect myself! How am I about to do that?!

I took his hand before he can panic again.

Me: You don't have to worry about me dying because technically both our souls are in your body, if my arm was chopped if it would grow back, but if yours was chopped off, mine would be gone too.
