Alerted by Misao, Kenshin and the rest of the Peace Force arrive to help Aoshi find a mysterious killer. Kenshin's investigation uncovers evidence linking the killing to a Christian Samurai and of vengeance that's been foretold.

When Kenshin accidentally loses all their money, the Peace Force must go to work at an inn in order to pay their bill.

Using the clues left behind by Dr. Hans, Kenshin and company are led to the hidden shrine that holds the key to the miracle cure.

As he faces off against the Black Knight's leader, Kenshin must rely on his brains and not his sword to win the battle.
