The Shinsengumi learn of Itou's plot to assassinate Commander Kondou. The Shinsengumi is dispatched to Itou's compound, in spite of concerns over Heisuke's safety. After Itou is assassinated, Saito and Chizuru confront Heisuke directly, and persuade him to fight alongside them against Itou's men. Meanwhile, Souji, severely weakened by his tuberculosis, is approached by Kaoru, who reveals his true identity and offers him a vial of the "medicine" that would heal him and make him a Rasetsu. Back at Itou's compound, the Shinsengumi forces are surrounded by Itou's men, Shiranui, and Amagiri. Heisuke engages Amagiri in battle, and is brutally attacked.
