About The Nightmaretaker: The Man Possessed by the Devil

The Nightmaretaker is a Japanese adult game by Sakuranbo Milk School, built on the Others engine with animated 3D CG. You play a male protagonist who changes jobs in object management after an incident. A devil possesses him and pushes him into predatory acts at a girls' school, framing his actions as abnormal urges and a demand to collect light. The story uses POV presentation and multiple endings.

The game is provided as an ongoing updated build, v1.7.1, dated August 9, 2023. It runs on Windows, uses edited machine-translated English, and includes mosaic censorship. The latest listed translation notes are for version 1.4 minor updates: they fixed look-around bugs in Sakura's and Aoi's stories, an untranslated boss choice, a Nanami monologue issue, and a Yuna clothing return bug. They also improved letter spacing and added Unifont and YuMincho fonts, with YuMincho as default.

Developer's description

A certain incident prompted you to suddenly change your place of work in the field of object management. You, who were supposed to be a good person, found a gap in your work and invaded a girls' school, and you fell into a sexual predator who sees through the napping schoolgirls. It's all the devil's fault. Ever since you was possessed by a demon, have been driven by an abnormal libido that want to ejaculate with a schoolgirl. If this continues, then someday it will be destroyed. But the devil whispers to you. The light that you can see when you ejaculate with the help of a schoolgirl: "Collect more of this light." In other words, ejaculate more with schoolgirls. The devil's true intentions are immeasurable. But the desire pushes you to criminal activity. A teenage schoolgirl with a fresh egg shines through, and a large amount of thick and sticky sperm comes out. A special sperm for fertilization that your body emits when you feel the existence of a girl who is old enough to give birth to a healthy child. This was rewarded with the sexual pleasure I received from this young woman.​
