About SiNiSistar 2

SiNiSistar 2 is an animated 2D CG side-scroller with combat and horror elements, made by Nennai 5 in Unity. You play an exorcist sister in Alcezon, a cursed town and nearby areas, fighting abominable creatures. The main quest has her explore dungeons across different locations and examine why monster numbers are rising, while sub quests in town or elsewhere can be tackled in an order you choose. Enemies absent from the main quest can appear in sub quests, with more planned for later updates.

The current build is v1.2.1, dated December 21, 2025, and development is ongoing. It runs on Windows and Mac, with English, Japanese, and Korean language options. The game is censored, and an uncensor mod is available. This update fixed a menu screen freeze under some conditions, resolved a bug that kept the Hunchback silent in some situations, and added missing images without tights.

Set in the cursed town of Alcezon and its surroundings, the player controls an exorcist sister and fights against abominable creatures.

Took what made the first game superb and further refined it into a masterpiece (by porn game standards). One of the best 2D platformers that i have found and played on this site. Incredible art, good platforming puzzles, well developed…

Not a fan of gore, but this is a great game regardless. Great art and gameplay. Atmosphere fits the game nicely and the sound is done well. Only downside is that there isn't more content. I'd love to see more…
