Riruka ha Ikue ni Yoru wo Irodoru

"I have other personalities," the girl said on the night they first met. Her gaze was serious as she looked at Shiraishi Naoya - the self-proclaimed detective - who responded by lighting a cigarette with a skeptical expression. At first, he didn't believe her. How could multiple personalities truly exist within a single body? There was the overly familiar 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 on a rainy night, and by a twist of fate, Naoya found himself bringing the "girls" home. She is a girl who carries multiple souls within her, and each personality holds a wish of her own - desires so powerful that they gave birth to new selves. When all of their wishes are finally fulfilled... what awaits at the end?
