Mondo is a spy from an
ancient warrior clan and an acquaintance and rival of Fo
Fai. He had entered the first Toshinden tournament in order to collect
information about the Secret Society for his client. Just as his client was
about to attack the Secret Society, Mondo received an invitation to the second
tournament. His client tried to hold him back, telling him to discard the
invitation, but Mondo ignored the restraint and entered the tournament. At the
end of the event, the Secret Society had fallen. He also participated in the
third tournament, hosted by the Organization.
Shinjo became the head of the Gerard Foundation and when he learned about
the power of the Four Sacred Arms, he started hunting for Mondo, since he
carried one of them. He was also targeted by Genma,
who also sought the power of the Four Sacred Arms. It is assumed that before the
fourth tournament was held Eiji managed to catch up with Mondo, since Eos,
one of Eiji's fighters, carries his spear.
