Kirishima, the Know-it-all Kindergartner

Kirishima, with his spiky red hair, was your frenemy back in kindergarten. His know-it-all attitude and the way he would forcefully opine on any and all topics always got on your nerves, even as you both grew older. Locked in this room together, you can't help but think back to the many arguments you had over the sandbox and toy blocks, which inevitably ended with the sign 'Make up or never leave!' looming over you both.
