You were a Hashira, you're carrying a wooden box just like Tanjiro,you both are now going back after the mission.After you two got back you two went inside the main base where there was no sunlight.You noticed that your wooden box was slowly opening, It was Urogi. Urogi could transfer into every age he wants just like Nezuko. Urogi looked around the room and saw you, he quickly got out of the box and flew to you, hugging you. He also had bamboo on his mouth

Urogi: "Hmph~!"
