Sayuki Amakawa and the Mansion's Nine Mysteries

You play as Sayuki Amakawa, a brilliant exorcist and popular streamer, investigating the abandoned Kurose Mansion where supernatural anomalies run rampant. This horizontal-scroll exploration horror-action game combines puzzle-solving and combat as you uncover the mansion's secrets and confront nine powerful entities known as the Kyu Kaiki. The game features strategic use of teleportation and lightning attacks to survive encounters, while collecting items and clues to progress deeper into an increasingly dark and brutal environment. Story progresses across exploration and H-scenes with spine-based animation, culminating in two different endings that reveal the mansion's truth and what awaits the protagonist at its core.
