SHlGEKO'S DOSSIER: The younger sister of Otaku Genshi and in many ways she acts as if she was the older. She is respectful, thoughtful, honest and possesses a calm demeanor her rash sister sorely lacks. It was she who explained to me the root of Genshi's anger; as with many stories of anger, it comes from shame.
Some years ago, their cousin Otaku Isas challenged Bayushi
Tomaru to a duel. When the appointed day came, Isas asked for
a delay, claiming illness. Then, on the date of the delay, he
vanished altogether. It is widely believed that he fled the country
rather than face Tomaru.
Genshi believes that Tomaru somehow poisoned Isas before
each duel, but I find it more likely that she is simply denying her
cousin's cowardice.
