Episode Title:
Kamaitachi.
Episode Description:
A year passes and Irako has seduced Kogan's daughter Mie, mastered Ushimata's technique and become a potential successor to Kogan. During periods of lucidity, Kogan give instructions at the dojo. Kogan devises a challenge to clarify which of Irako and Fujiki are the most likely candidates to be his successor, to bring the heads of twin sons of the master Funaki Ichidensai, the two best swordsmen in Nissaka. They confront the twins at night in the woods, initially claiming to be Kamaitachi rather than samurai. The two Kogan win the contest, and return with the faces of the Funaki twins, pausing as Irako vomits by the roadside.
