(Deku was walking through the hallways and went up to his locker to put away his diary, (first time he's put that diary down..)

"What have you got there huh?"

Asked one of the jocks and he looks at the locker and than at diary and takes it from izuku. 

"What's this your diary?" Asked the jock with a smirk.

"P-please put that down... Give it back.." said izuku as he reaches out for it. 

"No I'm reading this." The jock said.

Izuku snatches it and runs away as the jock pauses before yelling after izuku and following him, izuku turned corners to throw the jock off and than hides in the library, panting. Izuku leans against the shelf of books and looks at them, he takes one of them and opens it but accidentally cuts himself. 

"Ouch!" Izuku hisses as he pulls back his finger, blood dripping slowly from it.

"Great.. now not only do I have to deal with that jock but now I have to tend this papercut-..." Muttered izuku as he sighs, a beam of light shows in front of Izuku as he lifts his head to it and squints his eyes. 

"What in the...?" The gleam of light gets bigger and brighter as izuku covers his face with his arms shielding himself from the bright light, eyes squinted.

A tall figure in the light shows, red horns, red eyes with black around them, blonde hair, and a red tail standing at 5'8 atleast, with izuku being 5'4 he felt very short compared to the tall male.

Katsuki shakes his head from side to side for a minute before lifting his gaze and saying.

"What coward decided to summon me-" The blonde pauses once he saw izuku's face with his arms covering it, his eyes narrow a bit but he smirks slightly.

"How did you summon me..." Asked the blonde as he narrows his eyes more. Izuku just stayed silent unsure of how to respond.

The blonde pins izuku to the wall and repeats.

"How did you summon me." He says more harshly with a light growl. 

"U-uhm.. j-j-j-just a papercut-" Stuttered izuku as he lifts his bleeding finger and smiles sheepishly, still nervous.

Katsuki frowns a bit

"No wonder you were able to summon me..." He leans in a bit and izuku leans away slightly.

"Y'know you summoned me right when I was on break!" Frowned Katsuki as his eyes stare into izuku's.

"Name..." 

"H-huh.." replayed izuku.

"Your name, nerd." Izuku pauses and hesistates but says.

"Izuku.." Katsuki leans back and crosses his arms.

"That's boring.. how about deku instead."

"And.... What does that mean..?" Izuku tilts his head while Katsuki just smirks.

"It means useless, good for nothing." 

Izuku stares at him

"Why would you nickname me that, im not useless!"

Katsuki replies with a scoff

"Right.. and your not about to make that book shelf fall over.. " izuku's eyes shift to behind him as the books on the shelf starts to fall.
