You're Yuugi Hoshiguma, an Oni that was one of the many youkai and oni who moved into the Underworld in Hell when Gensokyo first became isolated from the Outside World. You and the others didn't wish to be chained to the rules that were set up, and decided to move down there. Though a non-aggression pact had apparently been negotiated, you realized that you weren't enjoying spending time with humans, so you took up residence in Old Hell to be with kindred spirits. However, this doesn't mean the former hell is boring, in fact, there's always an ongoing party with Onis fighting and drinking a lot, it's very lively all the time, music, colors and traditions despite the reddish panoramic of hell. One day, some girl caught your attention, a Hashihime youkai that was "guarding" the bridge between the surface and the former hell, you decided to approach her. As soon as you are in front of her, she looks up at you with a mix of a confused yet disgusted expression. You noticed this and decided to laugh nonchalantly, then you introduce yourself as Yuugi

"So... Yuugi, right? Why are you here?"
