Work Text:
At their next study session in one of UA's courtyards, Kirishima pulls out a speaker, and Izuku chooses mischief.
"Kacchan, can we play your music?"
Kacchan chucks his phone over without a thought, too busy failing to beat the quadratic formula into Kaminari's head. Excellent.
Kacchan's phone has the same pin that Kacchan has been setting since forever. Izuku makes short work of it, and opens the music app.
He hits play.
Kacchan's head whips around, brief bewilderment breaking over his face before his eyes narrow dangerously.
"You little shit."
And Izuku is bolting, a thud against the wall behind him as Kacchan presumably slams into it. Izuku will not be stopping to check.
He dashes across the courtyard, explosions sounding with every step. He janks sideways as Kacchan lands in front of him, narrowly missing a grasping hand.
"Shitty nerd!" Kacchan bellows. "Gimme back my phone!"
The Bluetooth disconnects and Kacchan's phone starts blasting something horrendously peppy at even worse volumes.
Fuck, it's a dead end- Wait, maybe-!
Izuku runs up the wall. An enraged shouts sounds from below, before explosions start catching up at a terrifying pace.
Right. Kacchan can fly. New plan!
Izuku drops. He catches a brief glance of Kacchan's intrigued expression on his way down.
Now would be a terrible time to develop heart problems.
He takes off back the way he came, eyes sharp for possible Bakusquad interference. At Aldera, Kacchan's minions would have cut off all escape by now, but his new friends are significantly less predictable in whether they'll take part in the chase at all, let alone on Kacchan's side of the board.
They like winding him up too much and crap, door, doordoordoordoordoor-!
Izuku bursts into the building and vaults over- fuck, he's getting detention later, fuck-
At least Kacchan is minimally slowed down by the presence of bystanders and an indoor setting. He's still too fast, though. Izuku jumps up, bouncing from wall to wall to wall, almost right on the beat- right, he should turn it down or something. Kacchan can probably track him just by the sound-
Ah. Fuck.
Izuku cannot run up this wall. It has a ceiling. One for All is a very versatile quirk, but Izuku has not yet mastered the complete defying of gravity with it.
Something to work on.
Izuku shoves the hand with the phone behind his back, putting on his best smile as Kacchan slams them both into the wall.
"You." Kacchan pants.
From between the elbows planted either side of his head, Izuku gasps, "Me!"
"I'm gonna kill you."
"Kacchan can do that if he likes." Izuku pushes forward into Kacchan's space. He feels a little lightheaded.
Kacchan makes a breathless, disbelieving noise, baring his teeth.
"Brat," he growls.
Izuku just hums. Something bubblegum and pink continues to play as Kacchan leans into Izuku's space and. Um. Uh...
Kacchan's eyes are brilliant vermilion crimson red, and close, so close, his face is really close-
"I win." Kacchan breathes, and the music abruptly decreases in volume.
Izuku hadn't noticed him taking back the phone. Stupid! Just a few more seconds, and-
And what? What was he hoping would happen? Kacchan would-
Izuku flushes probably almost as red as Kacchan's eyes.
The bombastic boy himself just smirks at him, crookedly cute, the left side pulling up more than the right. Izuku looks at it with probably more intensity than necessary. And Kacchan?
Kacchan grabs his arm and starts hauling him back the long, long way they'd come.
The Bakusquad isn't going to teach themselves algebra, after all.
