Do, was expected to be a great Bushi and an asset to the protection of Rokugan by guarding the wall. During the traditional Crab gempukku ceremony he went into the Shadowlands to bring back the head of a Shadowlands creature, but saw something that shook him to the core and threw him into a lingering melancholy. He was chosen to attend The Topaz Tournament not only for his skill but also in the hopes that being far from the wall would lift his spirits.
During the attack on The Topaz Tournament during The Story So Far, he was killed. After his death, his aunt Hiruma Mai asked Togashi Jiyu and (mantis) to take Do’s ashes on the adventure that he never got to go on.
