SiNiSistar / Nightmare

Studio Majin announced an anime hentai adaptation of the video game SiNiSistar. Release is planned for the end of January 2024. 

In the village of Kessaria, a gloomy and ruined place inhabited by disfigured monsters, Sister Rabian is tasked with investigating the destruction that occurred in one night. Moving through the dimly lit forest, she encounters demonic creatures that attack her. However, strangely, she remains unharmed, as if she had a nightmare. Between the nightmare reality and dreams, Rabian continues her journey into the unknown, where deformed creatures roam, and the line between reality and dream blurs.
