Anti-Hero: Type III. 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.
Evil Tastes Good: Just why is he so obsessed with causing as much pain to every immortal he finds? Because their time spores will taste so much better soaked with the memories of their pain.
