Madou Monogatari A: Doki-doki Vacation

Arle is spending her summer vacation at her grandmother's house, exploring the surrounding forest, when she discovers something troubling: a construction company under Satan's direction has plans to clear the forest entirely to make room for a recreational development. Unwilling to let it happen, Arle heads in to confront Satan's crew. The game opens with Skeleton-T, Sasori Man, and Suketoudara — three members of Satan's construction team — chasing Arle into the trees, kicking off the adventure.
