Shion, formerly known as Yamada Asaemon Shion, was the former 4th rank Asaemon of the Yamada clan.
After the shogun called for criminals to acquire the Elixir of Life from the dangerous island known as Kotaku, in exchange for a pardon for their past crimes, Shion joined in the expedition team as one of the Yamada Asaemon monitors and was assigned to keep watch over the criminal, Akaginu.
