chou enshin

First appearance: Battle 188
Type: Dou
Type: Satsujin Ken
Martial Arts: Chinese Kenpo (Pī Guà Quán and Bā Jí Quán)
Chou Enshin is a disciple of Ro Jisei and was once a member of Yomi, bearing the symbol of the Moon. He lost his position after being defeated by Tanimoto Natsu in a death match following Ma Sougetsu's return.
He is typically seen wearing a hooded cowl that completely conceals his features, up until his fight with Tanimoto.
As noted by Rachel, Chou remains very distant, having never been shown interacting with any fellow Yomi members before his death match with Tanimoto. He is often seen gazing out the window of one of Yomi's bases.
Chou is also extremely stubborn, refusing to heed his master's advice to step down and surrender his Yomi seat. Instead, he openly challenged Tanimoto.
