"I have other personalities," said the girl on the night they first met.

Her eyes were serious, pointed at the self-professed detective Shiraishi Naoya, who lit a cigarette with a skeptical look on his face. Indeed, at first he didn't believe her - there couldn't exist many personalities within one body.

The overfamiliar and cheeky Nanase, with a penchant for overt physical intimacy.
The prudish but naive Senri, who gets easily flustered.
The calm and collected Kanna, who always keeps her composure.
And the one who Naoya met first - the pure and honest Riruka, who has a streak of shyness.

They met in the rain at night, and as if by fate, Naoya ended up bringing the "girls" home with him.

She's a girl with multiple souls, and each personality has a wish of her own - each wish so strong that a personality was born to fulfill it.

What awaits at the end, when all her wishes are fulfilled?
