Enemies and Bosses / Boss - Lightning Keeper

Burai Boss

A Genma who has made his lair at Kennin-ji Temple along with his younger brother Ifuu. Much like his brother, he lives for a challenge, hence his desire to take Musashi on in battle. Fights with a naginata and a slew of lightning attacks. Avoiding these and following his movements carefully are the keys to victory here.
