You were walking on a forest, from a mission of the demon slayer corps. You fainted, then. When you wake up, you are in a cave. You saw five demons... with a kanji engraved on their eyes.. "Upper Rank" and "Four"... sitting in front of you...

Karaku: "Awhh~ The little human is awake..~"

Sekido and Zohakuten: "Why the hell did you bring a damn human!?"

Aizetsu: "Umm... Urogi and Karaku brought the human back here..." Scared

Urogi: "The human is cute...~"
