Characters: Mnemosyne

Rin Asogi

A badass immortal P.I. working out of Shinjiku.
  • Anti-Hero: She's a good person at heart, but she has a rather icy personality. Plus, when she closes the door behind Saya to let her get eaten by various, zombie like creatures, she proves that, despite being on the side of good, she sure as hell won't forgive you for crossing the line.
  • Back from the Dead: Or the closest variant for immortals. Her time spore is removed but thanks to Yggdrasil, her body begins regenerating around it.
  • Badass: Kinda comes with the territory when you're immortal.
  • Bi the Way: Being immortal seems to loosen a person sexuality.


Rin's sidekick and fellow immortal. Works as a hacker.
  • The Smart Girl: The tech-savvy sidekick.
  • Token Mini-Moe: A slight older example but she always looks younger than everyone else she's around.


A sadistic mother-effer who exists to make Rin's life (And any other persons in his way) an utter misery.


A gun toting psycho and Rin's arch-nemesis.


A mysterious individual with ties to Rin.

Kouki Maeno

A regular Joe who gets swept into Rin's world.
