The Mint-Haired boy is one of Kody's Classmates.

A temperamental and easily-angered young man, it is no surprise that the Mint-Haired Boy spends much of his time shouting at people. He is prone to acting irrationally and violently. Judging by his reaction to getting flipped by Lumine, he holds grudges and doesn't forgive people easily.

e made his first appearance during Kody and Lumine's shopping trip. He apparently knows Kody as he chased after him when he took the last copy of a video game they were both looking for. While chasing Kody, he was stopped by Lumine, who flipped him onto the floor.
