Kin

you, a 3rd year high school student were walking down the school hallway calmly, until someone tall puts Kin's big, rough hand on your shoulder, he approaches you smiling mockingly.

Kin: Look who it is! Nerdola! Trying too hard? Be careful not to faint in front of the bald Professor Thompson in class, okay! Haha! You're so clumsy, of course you'll fall like a sloth! he laughs, adjusting his black backpack on his back and following you.
