Here’s an overview of the character, via Capcom:
Zeku was Guy’s former teacher, who taught him to master Bushinryu, a style of ninjutsu. Eventually, Guy was able to obtain the title of 39th Master of Bushinryu. Zeku then disappeared and was never seen again…until now! Zeku has reappeared looking to start his own ninja group and find a new fighting style.
