SiNiSistar2

The bleakest pilgrimage in doujin gaming

SiNiSistar2 (RJ01169914) by circle Uu is the long-awaited sequel to one of the most internationally famous doujin action games ever made. You guide the nun Rabiane through a plague-rotted land of mud, rain, and cathedral ruins, on a mission that the game makes clear from the first screen will cost her everything. The circle describes its own themes as "masochistic tendencies, yearning for death, ruin" — and delivers precisely that.

What Uu does better than anyone

The pixel animation. Full stop. Rabiane's sprite work — her run cycle, damage staggers, and the infamous defeat sequences — is the genre's technical ceiling, and the environmental art builds an oppressive gothic mood that no other doujin circle matches. The sequel roughly doubles the first game's scope: more stages, more enemy variety, larger setpiece bosses, and a proper (grim) narrative connecting it to the original.

The action itself stays deliberately simple: light attacks, a dodge, ranged sub-weapons, and stage hazards that kill faster than enemies do. Veterans of hard platformers will clear it without much friction; the difficulty is emotional, not mechanical. Some mid-game stages (the cave and village sections) reuse ideas more than the openings, a criticism shared by Japanese and English reviewers alike.

The Steam release changes the buying math

For years, SiNiSistar was the poster child of "amazing game locked behind DLsite's payment wall." That ended in May 2026: publisher Sanuk brought SiNiSistar2 to Steam with a free official 18+ patch, making the Western purchase completely frictionless. DLsite still carries the official English version too — useful if you want to support the doujin channel directly (see our DLsite payment guide).

Verdict

As an action game, SiNiSistar2 is decent. As a work of atmosphere, animation, and committed artistic vision, it is nearly untouchable in the doujin space — a DLsite English Award winner for good reason. 87/100 — Excellent.

In Japan, SiNiSistar is one of the rare doujin action series whose circle name alone (Uu / うー) sells the product — the first game is regularly cited in "greatest doujin action games" threads, and the sequel launched directly into DLsite's overall top ranking. Japanese reviews converge on the same points that define the English discussion: the animation is treated as the industry benchmark (アニメーションの最高峰), and the game's despair-forward tone is discussed as its identity rather than a flaw.

Interestingly, the Japanese community frames the game's simplicity differently than Western critics. Where English-language reviews sometimes call the combat shallow, Japanese reviewers more often describe it as 割り切った設計 — a deliberate trade that keeps failure states frequent enough to showcase the game's real content. There is also sustained discussion of the game's horror imagery crossing into genuine grotesquerie; several high-rated DLsite reviews warn buyers that this entry is meaningfully darker than the first game. The sequel swept a DLsite English Award (Games, Silver) in 2025 on the strength of exactly this cross-border consensus.

Content is delivered primarily through defeat and grapple states during gameplay — the series' signature — plus stage-transition events. Animation quality is the genre's best. A full gallery with unlocked scenes opens on progress, and the game supports replaying any captured state.
