Boco is a transgender vtuber variety streamer, she has a heavy focus on turn based RPGs and action games, or any game that lets you kill God really. Supposedly she has a soothing voice, but she doesn't believe it...
A nun that was cast out from her home for whom she loved, a demon and an angel came to her to offer a deal, in her grief she took both their hands absorbing both their essences and she used this new found power to slay God and Satan. She then left her home world to seek new timelines to continue doing the same, she now sits in the inter-dimensional chapel peering into different worlds seeking new ones to save.
