Sweet Pool

Blood-soaked hallucinations turn an ordinary return to high school into a claustrophobic psychological horror story, where the person suffering is never sure whether his senses can be trusted. Sweet Pool is a boys’ love visual novel from Nitro+CHiRAL that follows Sakiyama Youji, a guarded student recovering from a serious illness, as disturbing bodily changes and impossible visions break through his daily routine. Its mood is intimate, unsettling, and tragic rather than action-driven, using school-life scenes and tense conversations to build dread around illness, identity, obsession, and desire.

Reading, choosing responses, and following Youji’s increasingly unstable perspective form the core of the experience. Decisions influence his relationships with the stoic Tetsuo and volatile Zenya, guiding the story toward different routes and endings while gradually revealing what lies behind the grotesque visions. Expect a focused, largely linear visual novel rather than a game built around exploration or traditional puzzles; the appeal comes from carefully paced revelations, character tension, and the discomfort of watching reality unravel. Mature sexual material and graphic body horror are integral to its themes, so its adult label is more than a superficial addition.

What separates Sweet Pool from lighter romance visual novels is its willingness to make attraction feel frightening, vulnerable, and inseparable from the central mystery. The striking character art contrasts sharply with scenes of surreal flesh horror, giving the story a distinctive beauty-and-revulsion atmosphere reminiscent of psychological anime horror more than a conventional dating sim. Multiple endings encourage revisits, especially for players who want to see how different choices reshape Youji’s fate and uncover the full truth. Fans of dark visual novels such as Saya no Uta, as well as readers who enjoy intense BL stories with horror at the forefront, find far more here than a standard school romance.
