Maa-kun

First-year student at Midoriyama Academy. A sweet young man who works as a part-time delivery driver for Dogen Hut and sends all his leftover money to his mother out in the country. Lately, however, he's gotten himself a girlfriend, and he's been sending money back home less frequently. His noodle house job doesn't pay enough to both support his mom and cover his dating expenses, so he's scheming for a way to make it rich quick.

He's taken the day off work today in order to attempt a dry run of the "Iron Stomach" eating competition, hoping to strike it rich while his girlfriend looks on. But after eating two parfaits, his stomach doesn't feel well, and has taken five trips to the toilet.
