Twin sisters Lisha and Aisha were born with complementary and opposing traits: Lisha possesses an extraordinary rational mind but is nearly incapable of perceiving or expressing emotion, while Aisha is highly sensitive, loves adventure, and cannot feel physical pain. During one of Aisha's expeditions, she discovers an abandoned temple from local folklore — said to have always been staffed by twins — housing a mysterious device capable of merging the souls of two twins together. Aisha urges Lisha to explore it with her. A cooperative adventure unfolds, demanding both the emotional spontaneity of Aisha and the cold precision of her AI companion AMBU — with multiple endings shaped by the choices you make together.
