Hell's Paradise is set in Japan's Edo period. Gabimaru, the strongest shinobi of Iwagakure village, sits on death row, but every attempt to execute him fails. Sagiri, an executioner from the Yamada Asaemon clan, brings him an offer from the shogunate: a full pardon if he brings back the elixir of life from Shinsenkyo, a legendary island southwest of the Ryukyu Kingdom. Other condemned criminals get the same deal, and each one travels tied to a clan executioner who watches them and will cut them down if they run. This page covers 16 characters in three groups: the convicts, the Yamada Asaemon executioners, and the strange inhabitants of the island. Every profile stops where the character is introduced, so there are no spoilers.
