Uncut
Curated by taste and lineage

You summon your way to 36 playable fighters and choose freely among them, and the only thing left standing between you and the ending is 36 consecutive boss fights, one after another, with nothing in between.

A pure boss-rush action game made and self-published solo by developer ジェッドム (Jeddom). Per Steam's own listing, you choose freely among 36 playable characters and fight your way through 36 consecutive boss battles to clear it; new characters are drawn through a summon system paid for with tickets earned by winning battles, and pulling a duplicate of a character you already have levels that character up instead of going to waste. It runs 2 to 6 hours to a single ending, set in a world where humanity's brains learned to interface with dark matter before science ever explained it, an ability people came to call 'magic,' turning modern society into a sword-and-sorcery fantasy centered on a boy named Saja. Per 4Gamer's own coverage, the character reveal posts from the creator's own account read like the kind of self-consciously edgy designs that feel like they belong in someone's own embarrassing teenage notebook, which is exactly what the title means: 'kuro rekishi,' Japanese slang for a cringeworthy personal past. Game*Spark's veteran indie reviewer Teruwaka Yoshida drew his own nostalgic comparison to the original characters he sketched as a kid, though that framing is his own reading of the cast, not an official backstory from the developer. Released October 23, 2025 at ¥500, it is Positive at 100 percent over 13 reviews (13 positive, 0 negative), a paid title, not free, fully launched and not in Early Access, with Steam Achievements, no AI-generated assets, and per Steam's own content descriptors, nothing sexual. It supports Japanese and English, yet none of its 13 reviews are in English, leaving it, with a review count this small, genuinely unfound rather than simply overlooked.

01First, the one feeling

02Who this is for (and who it is not)

For you

  • You want a boss-rush stripped to its purest form: no filler, just 36 consecutive fights and a roster of 36 characters to choose your way through them with
  • You want a genuinely solo, self-published Japanese production covered by name in Japanese indie press: 4Gamer's own writeup and a dedicated feature from Game*Spark's veteran reviewer Teruwaka Yoshida
  • You want a Positive title (100 percent over 13 reviews) that is about as unfound as a game can be: zero of its reviews are in English despite the game itself supporting it

Not for you

  • You want a large, statistically settled review base before you trust a score; 13 reviews is a small sample, and this pick says so plainly rather than dressing it up
  • You want a long story-driven campaign; this is a lean 2-to-6-hour boss gauntlet with one ending, a paid title, not free and not in Early Access, with no AI-generated assets and, per Steam's own content descriptors, nothing sexual

Kuro Rekishi Fighters Buried gem

Per Steam's own listing, this is an action game built around nothing but a boss rush: choose freely among 36 playable characters and fight your way through 36 consecutive boss battles to clear it. New characters are drawn through a summon system paid for with tickets earned by winning battles, and pulling a duplicate of a character you already have levels that character up instead of going to waste. It runs 2 to 6 hours to a single ending, set in a world where humanity's brains learned to interface with dark matter before science ever explained it, an ability people came to call 'magic,' turning modern society into a sword-and-sorcery fantasy centered on a boy named Saja who may save this chaotic world or push it further into ruin. Per 4Gamer's own coverage, the character reveal posts from the creator's own account read like the kind of over-the-top, self-consciously edgy designs that feel like they belong in someone's own embarrassing teenage notebook (their words for it: 'kuro rekishi,' or 'black history,' Japanese slang for a cringeworthy personal past), and in a separate feature, veteran indie reviewer Teruwaka Yoshida of Game*Spark drew his own comparison to the original characters he used to sketch and write profiles for in his notebooks as a kid, though that specific framing is his own nostalgic reading of the cast, not an official backstory stated by developer ジェッドム (Jeddom). Made and self-published solo, it released October 23, 2025 at ¥500, and is Positive at 100 percent over 13 reviews (13 positive, 0 negative per Steam's own review API), a paid title, not free, fully launched and not in Early Access, with Steam Achievements, no AI-generated assets, and per Steam's own content descriptors, nothing sexual. It supports Japanese and English, yet none of its 13 reviews are in English, leaving it, with a review count this small, genuinely unfound rather than simply overlooked.

Furi The critical echo

The origin of this taste: Furi, The Game Bakers' 2016 action game that strips a boss-rush down to its purest form, nothing but a sequence of unique, one-on-one duels against distinct opponents, with no regular enemies or exploration to pad the space between them. Kuro Rekishi Fighters is not an official Furi work, and this lineage is a comparison drawn by this site in outside critical commentary, not a stated influence from developer ジェッドム (Jeddom), but it carries the same core structure into a new frame: a game built entirely out of consecutive boss fights, where the choice of who to face next, and what you bring into that fight, is the whole design.
