The next morning

Katsuki woke up to see red eyes in his shadow.

He had just woken up, and thought he was just seeing things, so he blink couple times, and the eyes were gone.

The boy got out of bed, got dressed, and went downstairs.

-TIMESKIP-

Katsuki was on the playground with two other children. He had named them Fingers, and Wings because of their quirks.

They were asking him about the eyes in his shadow.

"I dont know.", he replied with a shrug.

The boys questioned on if it was his quirk, but Katsuki denied it, as it didnt feel right. Plus, he wasnt four, yet.

The other children were getting upset.

"Stop saying that!", Wings yelled.

Needless to say, all three boys went home bruised, bloody, and battered.

Midnight

That night, Katsuki was sitting on his bed, aching fist and busted lip keeping him awake.

Soon enough, the black and red swirls formed in front of him. The dual-eyed Deku looked at him and scanned him in (from what he could see in the dark) anger and concern. The man rushed up to Katsuki and knelt in front of him, cupping his face.

Deku tilted the blond's head ever-which-way, carefully wiping away the blood on his chin. He took in the sight of Katsuki's black eye, bloody lip, and bruised body.

Both if the silent man's eyes turned red in rage. Deku's mouth opened, and Katsuki could see the sharp, pearly white fangs in place of canines.

A deep, dark voice came from the orifice.

"Who did this."

It was a question, but a command from royalty, as for who would pay.

Katsuki didnt answer, but an impatient, "Well?", made him reply.

"J-just some extras from school.. It's nothing to worry about, they look worst.."

Deku looked him over, and soon, Katsuki felt cold hands over his eye and lip. The hands warmed and slowly, the blond's aches and pains disappeared.

The warm hands stayed, and Katsuki became sluggish and sleepy.

"Feel better?", the man asks.

Katsuki nodded and hummed noncommittally.

Deku lowered his voice to a whisper.

"Im going to give you something Kacchan; If you need me or something happens, hold it and say my name. Alright?"

"Yeah..", Katsuki murmured back.

Two pairs of hurried footsteps rushed towards the room.

Deku slowly pulled his hands back.

"Goodnight Kacchan."

"G'night Deku..."

Mitsuki and Masaru opened the bedroom door, only to see Deku's green eyes, and his dark swirl.

"Katsuki!", his mother shouted.

Masaru came up to him and grabbed his shoulders.

"Who was that?!"

Katsuki could barely reply. "No one, dad..."
