is a dimension traveler. Yeah, this story functions on the parallel world theory. When she dies, she truly dies, and her soul is then placed in a different, identical dimension. I haven't read it in a while, but that's basically what seems to be happening. So, yeah, technically, the time travel tag is false. It's actually transmigration, just into identical worlds. She doesn't always have all her memories either, as she dies an unspecified number of times. However, the crow remembers every time. He's the only one who remembers everything.
