Richou

Richou is a Felinoid Monk-Berserker from D.D.D. His Overskill is Artemis Fever. Like many other members of his guild, Richou originated from the fan fic D.D.D Diaries.

After D.D.D splits into the D3-Hub, a guild coalition formed from different segments of the former D.D.D, Richou becomes the guild master of the D3-Fu guild.

Appearance
Richou is a tall and muscular Felinoid with dirty-blonde and white fur and a few tiger-like stripes of black or dark brown. He wears a sleeveless brown shirt with a metal necklace or mantle, heavy gloves, and a green apron-like piece and orange-brown sash tied around his waist.

Fallen Guardian arc
He appears in the Akiba Raid Party's training grounds, where he has a  training match with Akatsuki, where she starts to use her small size as an advantage in combat.

Noosphere arc
Along with Kozaru, Yuzuko, Rieze, and Kushiyatama, Richou is among the five D.D.D members (or former member, in Kushi's case) that participated in the Shibuya Raid.

Trivia

 * In the light novel, he is with the Krusty army to finish the Return of the Goblin King event; however, in the anime he appears at the Akiba Raid Party's training grounds.
