Touken Ranbu character. He is the actual Yamanbagiri and a part of the Osafune school of swords.
Originally appearing as a mysterious hooded man, Chougi was brought over to the player's Citadel from the government.
He is polite with the Saniwa, but he is proud of his status as the original Yamanbagiri, and won't let people he considers inferior, such as Yamanbagiri Kunihiro or Nansen Ichimonji, off with that fact. However, he's one to lose his temper when someone doesn't give into his taunts.
