Score: 7.2 / 10
Rating: Good for niche audiences, skip for casual VN fans
COTE: Red Sonata v0.15.2 is a flawed but ambitious adult visual novel that succeeds at being a dark, tense alternate take on a popular IP. Steinercode clearly understands the core appeal of Classroom of the Elite (mind games, hidden motives, cold protagonists) and dials it up into R-rated territory.
However, the game's rough translation, repetitive grinding, and occasionally gratuitous cruelty will turn off players who aren't already fans of the source material or the darker side of adult VNs. If you want a power-fantasy where the protagonist is unapologetically ruthless and the heroines are both manipulated and manipulating, this is one of the better offerings in its niche.
Recommended for: Fans of Classroom of the Elite looking for an adult fan-sequel; players who enjoy Kara no Shojo, Saya no Uta, or Euphoria's psychological extremity.
Not recommended for: Anyone seeking wholesome romance, canon-compliant COTE stories, or players bothered by non-con content and rough translation.
Review completed after one full playthrough (all available routes as of v0.15.2). No developer compensation was received.
If you are worried about spoilers for the light novels, don't be. While the school rules and location are the same, Ayanokōji, Horikita, and Kushida do not appear as main characters. They exist in the background as "untouchable legends." COTE- Red Sonata -v0.15.2- -steinercode-
Instead, you play as an original first-year student placed in Class 1-D (a different D-Class than the canon one). Your goal? Raise your class to A without getting expelled.
The official distribution point is the -steinercode- Itch.io page. As of this writing, do not download from third-party repack sites—the v0.15.2 build contains a unique watermarking system that phones home if the checksum is wrong. The developer has used this to push fake "bad endings" to pirates.
For everyone else: tune your frequency, accept the lock on your saves, and let the Red Sonata play.

If you are a casual Classroom of the Elite fan looking for a light dating sim or a power fantasy, avoid this build. Red Sonata is cruel, unforgiving, and deliberately obtuse.
However, if you are a connoisseur of emergent narrative, mechanical diegesis (where the game’s UI and save system are part of the story), and the raw, unfiltered vision of a developer like -steinercode-, then COTE- Red Sonata -v0.15.2- is a masterpiece in progress.
It is not a game you complete. It is a game that calibrates you.
