How to accidentally summon a demon

Oh there are more?!

Bakugo's POV:

I felt Izuku's grip on me tighten as Lamech turned into a hellhound and exited the kitchen. I went to move but he kept his grip, sighing, I picked him up toddler style and placed a barrier around us. I turned the corner when I saw two people who I remember seeing the day I visited UA.

Me: Who the fuck are you two?

Izuku had a look of fear and literally jumped off me and hid behind the wall down the hall.

???: I'm Mineta and this is Kaminari, Mr.Nezu sent us to deliver your school supplies.

Me: What does this have to do with you coming in my house?

Izuku: White....Kacchan they are white!

I was going to look at him when the two males turned into white lights.

Me: I don't know how to feel about this.

I looked at Izuku who was next to me now.

Me: can you both like... stop? It's the middle of the morning, the sun isn't even up yet.

The one I kind of know as Kaminari stopped and was shocked.

Kaminari: Why aren't you on the floor in pain?!

I shrugged and pointed at them, a low growl filled the house and the two angels stepped back as multiple hell hounds came from upstairs.

Izuku: How... Kacchan...

Me: I am not Lord Lucifer's favorite for no reason. Now I'm giving you both a chance to leave peacefully, if not, these good boys will chase you till the end of time.

Mineta: How are you still withstanding the light?

Kaminari: We can't we have orders from the higher ups!

Me: Well then, I'll see you around.

I brought my hand to my mouth and whistled shrilly, the hounds snarled and ran after the angels who ran out the door before disappearing, I guess they turned invisible because the hounds kept chasing after them as they turned invisible too.

Izuku walked up behind me and rushed to close the door. I sagged down and took a few breathes in.

Izuku: What was that supposed to tell us?! And since when are angels like that?

I got up and rushed to the kitchen, the soup was nearly overflowing from the pot.

Me: It means that we're... on the radar... and you need to learn control of your quirk.

Izuku: Can I even hurt angels?

Me: All quirks can hurt angels and demons, you just have to get it powerful enough.

Izuku: Also what you mean control my quirk?! What you think I was trying to do for half a year?! I am already trying! You know damn well I was born quirkless... so excuse me that my sorry ass can't control it because I didn't have a lifetime and more of a chance to do so.

Me: Izuku, darling. Breathe.

Izuku: Don't darling me! Screw off! Everyone tells me that but guess what?! I am already doing my best and I didn't ask to summon you! I just found a goddamn book in the library of UA.

I watched as lightning arched off him as he ranted on.

Interesting.

Fucking quirk.... Always getting me when I get angry....

I looked at Lamech who pulled a book from out of thin air, he handed it to me and I opened it, flipping a few pages.

Me: Izuku, get something to eat, I'm going to do some research about your quirk ok.

Izuku: You don't have to tell me that. Good luck it's the quirk of multiple dead people... and it is different from user to user as well.

Me: I know, but I am a demon that can summon ghosts, give me a few minutes or hours.

Izuku: Yeah but still doesn't help me since I have to actually control it.

Me: Freckles, your sass isn't getting you anywhere.

Izuku: Ah whatever! Do what you want.

Why does everyone think they can actually tell me something about this goddamn quirk!

I still have to controll it and not someone else!

Not as if I didn't get my hands on analyzing it myself!

Theory is easy but doing it in real life... NAH-AH two different things!

Can't believe he just got my weak point and tries to exploit it.... He is already perfect but me nooo he has to try change me to get powerful! What's up with that! Do I want to have this quirk?! NO! Did I try to give it to someone else? YES but nope it doesn't want to leave me be! *sigh* ama go eat something... maybe I can find something sweet as well.....

I watched the lightning again and left the room. I wasn't actually going to contact the past users. I know Izuku and I just wanted to test a theory of mine. I looked at the eye above the mirror in the closet and knocked on it.

Lucifer: What is it Katsuki?

Me: How can I help Izuku? His quirk is literally destroying him and he can't even give it away so why is he going through so much?

Lucifer was silent for a while before he spoke up.

Lucifer: God gives his strongest soldiers the hardest battles.

I was pissed off.

Me: No riddles! Tell me! I can't take it! He deserves to be happy too!

Lucifer looked like he was smirking.

Lucifer: Well look at that, my favorite demon is finally concerned for someone besides Lamech and himself.

Me: whatever.

Lucifer: Well Izuku has to spread the power throughout his body, not just keep it all in one body part, and he has to keep his emotions in check too, his emotions are also tied to his quirk...it'll take a while but you and Izuku will work it out, he's just under a lot of pressure.

I nodded and went to exit the bedroom, I opened the door and saw Izuku standing there, his hand raised to knock, I ignored that for his eyes, they were misty with tears. I pulled him close and hugged him tight, his hands wrapped around my neck and he wrapped his legs around my waist.

Izuku: I shouldn't have let it out... sorry...

Me: Izuku, it's fine. I'm not mad ok?

He nodded and tightened his hold on me. I felt his tears soak into my shirt. I laid on the bed, Izuku stuffed his face into my chest as he sobbed even harder, I let him stay there till he fell asleep, his grip still strong as ever.

Izuku: Kacchan.... Promise... I will keep it... I will.....

I'm sorry for hurting you like that Izuku,

I kissed his forehead and hugged him close, Izuku shifted slightly, a sad whine escaping his lips. I rubbed his back till I fell asleep with him on my chest.
