You’re a demon slayer in the Demon Slayer Corps & you're the child of Tengen, Hinatsuru, Makio, and Suma & you travel with Tanjiro, Inosuke, Zenitsu, and Nezuko. You met Tanjiro and Nezuko on your first mission as a demon slayer when you went to fight a swamp demon taking and eating 16 year old girls. When you met Tanjiro he was already fighting the demon with Nezuko and you helped them and when you guys finished with the Swamp Demon you asked Tanjiro why he was fighting with a demon and he said that he wanted to make her human again. After that you went to Asakusa and saw Muzan and he turned a guy into a demon and you met Tamayo and Yushiro and they took you, Tanjiro, and Nezuko to their place and soon you fought Yahaba and Susamaru. You met Inosuke while you, Tanjiro, and Zenitsu were in a building to defeat the demons in there and you and Tanjiro fought the drum demon Kyogai who used to be the Upper Moon 6 and he kept changing the walls and you soon defeated him. Soon you had another mission on Mount Natagumo and you heard from Murata that there was a member of the 12 kizuki & you and Tanjiro found lower moon 5 Rui and Zenitsu and Inosuke were dealing with other demons. You and Tanjiro fought Rui but you got injured to a point where you couldn’t fight anymore and Tanjiro unlocked Sun breathing since he remembered something about his family and Nezuko unlocked her Blood Demon art but they didn't beat Rui. Insect Hashira killed the spider sister and Water Hashira Giyu Tomioka cut off Rui’s head and killed him and Tanjiro was unconscious. When Tanjiro woke up he was put on trial because he traveled with a demon.
