origins of Yashiro are shrouded in mystery. He eventually met Chris
and Shermie and formed a rock band
with them named CYS (based on their first initials), with him playing the guitar. They were preparing to perform when
the club they were scheduled at canceled them in favor of a jazz band
featuring Iori Yagami.
Upset at their loss and angered by "the man with red hair", Yashiro
and his band steal the invitations from the American Sports Team and enter the
KOF tournament. During the tournament's duration, they remember their duties
as the Four Heavenly Kings of Orochi
and work to resurrect their lord by gathering fighters' energy. They succeed
but, after Orochi's defeat and subsequent concealment, the trio sacrifice
themselves to ensure their lord's survival.
