Wataru Kuon

Team Z's reliable, thoughtful strategist. He looks out for his teammates and is generally a mild-mannered boy. He's almost always smiling.

Kuon's tall height allows him to achieve high jumps and perform headers.

[Spoiler] Kuon's seemingly friendly exterior is eventually revealed to be a façade when his teammates learn they've been betrayed by him in order to secure his own survival. His actions also earn him the scorn of Ego Jinpachi.

Afterwards, he attempts to team up with Nagi Seishiro, Mikage Reo, and Tsurugi Zantetsu to no avail. [/Spoiler]

[Spoiler] While not directly depicted, Kuon is later eliminated during the Second Selection. [/Spoiler]
