Gabimaru

Gabimaru served as Iwagakure's most infamous shinobi until he was betrayed by his village for wanting to abandon his role as a murderer and live a peaceful life with his wife. This resulted in him being handed over to the authorities to be executed. However, after the shogun calls for death row convicts to compete in acquiring the Elixir of Life from an island believed to be Shinsenkyō in exchange for a pardon for their past crimes, Gabimaru receives an invitation from Yamada Asaemon Sagiri to be a part of the competition and accepts in order to reunite with Yui and live the life he so desired.
