Ootsumuji

Ootsumuji is armed with the Senpū Ōgamatō (旋風大鎌刀?, Whirlwind Scythe Sword) and uses his hair to create gust of wind to hit his opponents in his Shinkūtsumuji Muchi (真空つむじ鞭?, Vacuum-Whirl Whip) attack. Send to terrorize humans by causing massive damage and gathering all humans in the area, Ootsumuji is the first Ayakashi to be slain by Shinken-Oh. Ootsumuji's appearance and abilities made him the origin of the Kamaitachi (窮奇?).[9]
