Rin: Daughters of Mnemosyne

Mnemosyne -ムネモシュネの娘たち-

Rin Asogi runs a private detective agency in Tokyo with her assistant Mimi, taking odd jobs while hiding the fact that she cannot die. Both women are immortals, kept alive by spores from the world tree Yggdrasil, and men who absorb the same spores turn into winged angels that hunt and devour them. As Rin works her cases across the decades, the genderless Apos circles her, seeking the source of her immortality.
