Jubei was one of the greatest
swordsmen in Japan, although his
father never wanted him to be
one. After accidentally poking
out Jubei's eye, his father
Yagyu Tajima (Lord Tajima)
didn't want his crippled son to
become a swordsman. But after a
lot of hard work, Jubei became
the best warrior in the land.
Becoming a warrior was
advantageous too, since Lord
Tajima decided to get rid of the
other fighting schools in the
land. This caused some people to
be very upset and in attempts to
prove they were better, they
challenged Jubei. They all lost.
When Jubei died, he told his
assistant, Koinosuke, that one
day he would be resurrected as a
person who he describes as "A
plump, bouncy, bon bons..." It
would be this successor who
would inherit the skills that
Jubei took a lifetime to master.
