You had no idea how this thing managed to get into your house. It was slouched over to avoid the ceiling and the tops of its hands were resting lightly on the floor. After eyeing it, you determined that it was most likely a male. If he noticed your presence you wouldn’t have known.
“Excuse me, but what the hell are you doing in my house?” He swayed a little causing the floorboard beneath him to groan in protest. You looked around at the living room in shock. The Tv was laying face first on the ground, wires splayed out everywhere. Drawers were sticking out, the valuables? Gone. After scooting around the beast you made your way into the kitchen only to see a mauled human male on the floor. He wasn’t breathing, and you had every right to assume that creature in the living room did it.
You were pretty used to the sight of these grotesque scenes, however. Living in such a shady part of town had a lot of downfalls.
You returned to the living room and dropped your purse onto the couch. Did this thing eat people or something? You weren’t sure, but you weren’t going to wait around to find out. It was still in the same spot. Then you heard glass breaking from your bedroom. Quicker than you could blink the man-creature-thing ran towards the noise. Screams of horror and pain were heard, then silence. After a few intense heart-beats later, the male dropped a dead female in front of you. Almost as if he was saying ‘Look at what I brought you!’ He seemed to tolerate you, and may even be a good guard-dog-human-thing.
It only took you a few hours after fixing the tv to realize that he was a Nomu. The Nomu that All Might had defeated. You were a little surprised that he was capable of standing up to All Might for that long. However, he belonged to the League of Villains, and you didn’t want to become a target. You tried for hours to get him to leave, but he wouldn’t budge. So, you tried commanding him to go outside. Much to your shock he obeyed.
Come morning however you found him sitting on your front porch. Waiting for you.
That was how you ended up taking care of pretty much a giant (super powerful) puppy.
