However, due to his superhuman levels of training, he has inadvertently survived multiple executions, from attempts at beheading to burning at the stake. The executioner Sagiri Asaemon tells him that he has lingering attachment to life, and issues him a mission to win his acquittal: to find the elixir of immortality.
