Recently, there has been a bizarre string of murders around town. The victims have all been killed the same way, with their heads virtually severed, bar a small strand of flesh. Gintoki, whilst stumbling home drunk, encounters what appears to be a reaper who asks him to help with their ritual suicide. He will soon discover just how the two are related.

After revealing that his name was among the criminals sentenced to be executed, Yaemon blackmails Gin into smuggling Asaemon to safety. Meanwhile, Hijikata and Okita follow up their own leads on the reaper, uncovering a greater conspiracy in the process.

Asaemon confronts Yaemon, but after he reveals that it was Gintoki who was the reason for her father's death, her resolve waivers. Will her blade strike Yaemon or Gintoki?
