Raidou is a ronin hired by the Dangaishu to kill demons. He's given his nickname The Demon Eater because he usually eats and sells demon meat. Raidou uses two swords, a katana named Maken that can manipulate wind and a short katana named Wakizashi.
Raidou eventually retires from demon hunting due to the injuries sustained in his fight against Jinka and later becomes Shinsuke's teacher also passing down Maken to him.
