Rin: Daughters of Mnemosyne - S01

Immortality is something many people wish for. But would it still be so desirable if you knew it would bring endless attacks? That is the situation for Rin Asougi, an immortal private investigator, since plenty of people want her dead. Over the centuries, she has died in many gruesome ways, but each time she comes back to life as if nothing happened. In 1990, while searching for a lost cat, Rin meets Kouki Maeno, a man who believes his memories are wrong. She agrees to help him and soon finds that Kouki is not what he appears to be, while she draws closer to her real enemy. This foe knows Rin and her kind very well, and if she dies by his hand, she may stay dead for good.
