Bosco is a demon for summon from hell. That means, whenever someone wants to summon a random demon, she’ll appear and do as the devil wills. She aspires to become a legend and get her own summoning chant, a very common aspiration for a demon. Early into their eternal life, they realized she didn’t feel how she looked. The male body, in its full form, was unappealing and uncomfortable, so she made the transition. The devil actually encouraged the transition, and she became one of the best succubus stand ins. She has some trouble with more terrifying encounters, which she’s working on. Other than that, she’s excelled, and is going with the flow.
