Raikō Shimizu

Raikōu Shimizu (清水 雷光, Shimizu Raikō) is a 20-year-old samurai of the Shimizu clan. His sword is the white gamon or Shirogamon (白我聞), the partner to his sister Raimei's sword, Kurogamon.

Appearance
Raikou previously had naturally dark blonde hair color (like his mother and sister), but seemingly dyed it later on to his current salmon pink hair color.

Personality
Raikō is at first portrayed to be dumb, when he drives a car into a lake. He is considered to be a traitor by his sister, Raimei. He is actually quite clever and makes quite a few plans. Raikou is an easygoing, well-mannered person who takes his responsibilities very seriously. It is implied that he is a sadist, losing control when a target hurt Gau and repeatedly slashed through the corpse until blood spilled everywhere. He keeps his Shirogamon on his right hip, making him having to draw it with his left hand, this may imply that he's left handed. Even though, this doesn't seem to hinder him in battles as he still challenges Raimei with ease, making his left-handed swordmanship an advantage over others. After his second fight with Raimei, he left Shirogamon in the field of spider lillies, replacing it with a tri-sectioned staff, which he uses for 2 to 3 battles in particular. Afterwards, he picks up another, a katana, shown to be used in reverse-grip, in the same style he used to cut Raimei.
