Kiken na Mori Onigokko

A young girl named Alps embarks on a desperate mission to save her gravely ill sister by seeking a rare herb found deep in a dangerous forest. Simple enough premise, right? Except this forest is not the kind you take a casual stroll through. Within minutes of stepping inside, Alps runs into shady men and faceless demonic creatures, and her herb-gathering mission turns into a brutal game of tag where getting caught means something far worse than losing. The title literally translates to "Dangerous Forest Tag," and it delivers exactly that — a dark, suspenseful chase through a nightmare landscape where every shadow could be hiding something terrible. This is an OVA adapted from a game by studio Majin, and it leans hard into its dark fantasy roots with detailed character designs and an atmosphere that stays tense throughout. The forest itself feels like a character, oppressive and alive with threats. If you liked the eerie forest vibes of Hotarubi no Mori e but wanted something with genuine danger and horror elements, or if Dark Gathering's supernatural tension was your thing, this scratches a similar itch — though fair warning, it carries a hentai tag, so know what you're getting into before you press play. The core emotional hook of a sister risking everything for family gives it more narrative weight than you might expect from the genre.
