His attacks include Full-Body Blades (全身刃, Zenshin Yaiba) and Shuriken Turbulence Shot (手裏剣乱れ撃ち, Shuriken Midareuchi). He goes to fight the Shinkengers to avenge Isagitsune, nearly killing the five before he falls back into the Sanzu River.
By the time he resumes his campaign of vengeance, the Shinkengers have ShinkenGold by their side. He is destroyed by a Fiery Dance/Hundred Fillets combo, Hyakuyappa battled ShinkenOh upon being revived before ShinkenGold arrives in the Ika Origami to form Ika ShinkenOh who freezes the Ayakashi before finishing him off with Squid Flash.
