RIN: Daughters of Mnemosyne

Overview

A mysterious tree known as Yggdrasil would often appear in the world of the humans, releasing many small orbs into the human world. A small proportion of the orbs are special ones known as “Time Fruits”. If a Time Fruit enters a female, she becomes Immortal. If a Time Fruit enters a male, he becomes a crazed winged being known as an “Angel”. Rin Asougi is an immortal who runs a private investigation agency in Tokyo’s Shinjuku district alongside her assistant, Mimi who is also immortal. Rin often converses with a mysterious unknown individual on the phone. She is often being hunted down by an assassin named Laura who was hired by Apos, an angel who persecutes immortals and is the current guardian of the Yggdrasil.
