The protagonist Meisa (20), who hails from the countryside and dreams of the city, moves to Tokyo to continue her studies and lives a fulfilling life. While on a trip with her best friend Moe from high school, Meisa happens to meet her childhood friends Ryo and Kyoya, who are also on the trip. The three were born and raised in the same rural town. They spent almost every day together from childhood to middle school, but for some reason they became estranged for several years. Although it was never fulfilled, Meisa and Ryo once had a faint crush on each other... Meisa is happy to be reunited with the two, but from that day onwards she is paralyzed and begins to have lewd dreams. Every time she sleeps, her pleasurable spots are relentlessly stimulated, but she is stopped just before she reaches orgasm and is never allowed to climax - her consciousness is gradually dominated by pleasure... Meisa becomes confused as strange things start happening in the real world, such as the person she likes suddenly avoiding her for no apparent reason and her close friends becoming unwell. Then Kyoya, who looked after her like an older brother when she was a child, comes to her rescue. Meisa is touched by Kyoya's unchanging kindness, and the two of them gradually become closer. However, Kyoya has a secret feeling in his heart that he has never confessed to anyone... [What is a living spirit?] A spirit of a living person. A spirit that is born unconsciously from strong resentment, hatred, love, etc. It possesses the object of obsession. A troublesome spirit that acts regardless of the will of the person who created the living spirit. *There is no element of coercion.
