The Abyssal Phoenix; the being born of death. Abyssal Phoenix is a multiverse story where the MC, Sera, travels through various universes. I.E: Tensura, Godzilla, Overlord, etc.
The MC is extremely strong, and overpowered most of the time. She isn't completely evil, but doesn't really care about the lives of the people she doesn't know. She's morally dubious. There will be no romance in this story.
