Richou

Richou is a Felinoid Monk-Berserker from D.D.D. His Overskill is Artemis Fever.

After D.D.D disbands and reforms as a coalition of multiple individual guilds known as the D3-Hub, Richou becomes the guild master of the D3-Fu guild.

Like many other members of his guild, Richou originated from D.D.D Diaries, a fan fiction work that was raised to quasi-canon status in the Japanese Log Horizon fandom.

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
Richou and Kugel are members of the scouting team that accompanied Krusty to Seventh Fall to eliminate the Goblin King and wrap up the Return of the Goblin King event.

In the anime, he remained in Akiba, where he assists in training the Akiba Raid Party for their battle against Enbart Nelles. 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 Party.
