The Spirit of Yarikawa's Vengeance is a Mythic Tale in the Ruins of Old Yarikawa, Toyotama. You follow offering shrines to a vengeful spirit and learn the Dance of Wrath, a three-hit unblockable katana technique.
Part 7 of 9 in Mythic Tales
Clan Yarikawa passed a secret sword move, the Dance of Wrath, to one lord each generation. Lord Tokiasa Yarikawa mastered it and led a rebellion against Clan Shimura, killing Lord Shimura's father and brothers. Shimura and Clan Sakai crushed the revolt and executed him, and locals now pray to his spirit for revenge.
Search Old Yarikawa for white smoke and read the offering scrolls. One asks the spirit to destroy a Mongol camp by the river, which you find already wiped out, with one survivor in a cage. Another names a villager called Heitaro as a traitor; in the survivors' camp you learn he only slips out at night to visit a friend's grave. A third shrine is empty, and the sound of fighting leads you to a house full of offerings. The last scroll asks for your own death in the Garden of the Gods.
Once the spirit's health drops below a quarter, the game prompts you to use the Dance of Wrath. In later duels it works as a heavy damage move, and it carries on after a deadlock. It also stacks with the Way of the Flame.
You meet the spirit in the Garden of the Gods, but it never shows who is behind the mask. You defeat it with the Dance of Wrath, which makes you the last living master of the technique.
