Gyo Shiromutsu

Gyou Shiromutsu is the estranged longtime ally of Rasetsu Kagemusha. They have been friends since their first day at Toudou Academy, but it is also heavily implied the two share a friendly rivalry. On the outside, Gyou can seem like a goof and weakling, and is often overlooked by other fighters at Toudou. However, Rasetsu is the only person that "knows the true extent of his abilities" Gyou serves as a hermit-type character in the series.
