Yumada Genki

Yamada Genki

Yamada appears once in chapter 15 of the first season bringing some curry to Tokuta's siblings, who are fighting. Whether he goes to meet Kamimaru at his cube the next day is unknown. He is one of the five survivors from cube 99, along with Matsuno Juri, Ashida Kouzou, Shimura Shin and Tsuda Yoshika. He knows Tokuta Takuto, though they weren't in the same cube.
