- What is this wiki all about? ... an immortal woman. Rin Asogi, a woman desired by both men AND women, has lived for over a thousand years, and most of them searching for a man she met when she became an immortal. During all of this time, she has experienced all sorts of deaths, surviving all of them.
- She is currently the head of her own detective agency within Tokyo's Shinjuku ward - Asougi Consulting - which she runs along with another immortal woman, a waifish woman with teen looks named Mimi. Between shots of vodka... as well as Rin's bouts of procrastination, the two struggle with cases that are about as mundane as finding a lost cat... to figuring out about a young man that is part of Rin's bigger mystery. All the while, Rin fights against a certain foe - Apos - who hopes for the immortality Rin has, and has tormented and hounded her for all those thousand years!
