甘き来訪者 ～SWEET FROM BEYOND～

Wakana, a full-time housewife, leads a peaceful life with her husband, her younger sister Nanami, and her parents. However, after a mysterious fireball lands in their garden one night, strange phenomena begin to unfold within the house. An inexplicable, sweet-smelling odor permeates the home; sugar begins to proliferate as if it were a living organism; and the family members undergo bizarre transformations that erode both their physical and mental well-being. As they gradually lose their grip on reason, they cease to hide their increasingly lewd behavior. Io—a light novel author and childhood friend of Wakana—begins an investigation after hearing from Nanami about the strange occurrences, only to find himself and his companions confronted by an inescapable terror. (R15+ version premiered at the OP Pictures+ Fest 2026)
