Infinity Nado S07 E14 Legend of the Rock Monster

Hersh and his subordinates return to their boss, after failing against Kareisha. Hersh explains to his boss that he was defeated after Kareisha got a new nado, and increased his strength. Hersh then says his combat power is too weak. But instead of punishment, his boss gives him a new mission. Hersh is to go to Crystal Cave, find a nado called "Shatter Wind Blast", and bring it back while both defeating the trio and getting Super Demon Lord.
