Your phone goes missing, and when you check its GPS, the pin is sitting on an old western-style mansion deep in the mountains — a place you’ve never been, with a reputation nobody wants to talk about. That’s the setup for Last Known Location, a side-view exploration horror action ADV from Studio digima starring Miyua, a busty jirai-kei girl who walks into the dark to get her phone back. If you like your ero games with actual survival-horror tension — zombies you can fight, a stalker you can’t, and a clothing-damage system that punishes every mistake — this one is aimed squarely at you.
What works
The premise is a genuinely good horror hook. “My lost phone’s location data points to a haunted mansion” is a modern, relatable anxiety turned into a reason to explore somewhere you absolutely shouldn’t, and the game layers a personal mystery on top of it: Miyua has gaps in her memory she’s convinced are “normal,” and she has no recollection of ever visiting the place her phone ended up. Creaking corridors, a basement where the lights have died, something shuffling through the halls, and the promise that all the answers are waiting at the deepest level of the mansion — it’s a clean, focused setup that gives the exploration a real pull downward.
The threat design is the smartest part of the package. There are two kinds of danger and they demand opposite responses: regular zombies can be met head-on with weapons in depth-based side-view action, but the “stalker” enemy cannot be killed at all. When you hear its footsteps, your only options are to run or hide. That split — fight the small threats, flee the big one — is classic survival horror structure, and pairing it with dark zones, trap-filled rooms, and hidden passages means the mansion isn’t just a corridor between H-scenes; it’s a puzzle box you descend through by finding items and solving riddles to unseal locked doors.
The ero side is built directly into that danger rather than bolted on. Getting grabbed triggers a struggle system — mash to break free, and if you can’t, Miyua loses her clothing one layer at a time. The three-stage system (clothed, underwear, fully nude) is persistent: stripped clothes stay gone until you actually change, so a bad encounter leaves you exploring the mansion in a much more vulnerable state instead of resetting to neutral. Get caught while nude and it goes straight to an H-scene, animated in Spine, so the scenes move smoothly rather than being static CG flips. Add voice acting, a music credit, four endings, and a gallery for rewatching scenes, and the feature list covers everything you’d want from this subgenre on paper.
What doesn’t
The usual structural tension of defeat-based ero applies here in full. The H content is punishment content — you see it by getting grabbed, failing the struggle, losing your clothes, and then getting caught again. Players who want to experience the scenes will end up throwing runs on purpose, which always sits a little awkwardly against a game that’s simultaneously asking you to take its horror seriously. The unkillable stalker is great for dread but can also turn into a patience test, because footsteps-run-hide loops in games like this live or die on checkpoint generosity and hiding-spot placement, and the store page tells you nothing about either.
The bigger issue is how much is unspecified. The description doesn’t say how many H-scenes there are, how long the game runs, or how large the mansion actually is, and the price wasn’t confirmed at the time of writing. The developer explicitly asks buyers to try the trial version before purchasing to confirm the game runs on their machine — take them up on that, and use it to gauge the movement and struggle mechanics too, since a grab-escape system that feels bad in your hands will sour the entire loop.
Who should buy this
Be aware up front: this is a Japanese-only release with no English support. The good news is that it’s an action-and-exploration game rather than a text novel, so an English speaker can get most of the appeal — the animated scenes, the strip system, the chase tension — without reading much. The catch is the puzzle side: progression depends on items and riddles unsealing doors, so expect to lean on a texthooker or phone-camera machine translation when you hit a cryptic note or mechanism. If you’re here for zombie and interspecies content, dub-con scenarios, a big-breasted twin-tailed protagonist, and Spine-animated defeat H wrapped in real survival-horror mechanics, it’s worth the friction. If you need to follow every line of the mystery about Miyua’s missing memories, you’ll want functional Japanese.
Verdict
7 / 10. On paper this is a well-constructed defeat-ero horror game — the fightable-zombies-versus-unkillable-stalker split, the persistent three-stage clothing system, and Spine-animated scenes are exactly the right ingredients — but with scene count, length, and price all unconfirmed, the free trial should be your first stop before committing.
This is the Japanese-language store. International credit cards and PayPal are accepted. The game itself is in Japanese.
