Horror and comedy make an uneasy pairing in fiction generally, and a story that leans hard into one after opening with the other risks reading like two different works stapled together. Kimagure Temptation opens by leaning about as hard into horror as a visual novel can. Four bodies turn up with their organs removed, and a miasma thick enough to poison the air hangs around the crime scene. Then a demon shows up looking for otaku merchandise and a place to crash, and the whole tone drags sideways. Getting used to that whiplash took the first hour or so, and after that the mix stopped feeling like a flaw and started feeling like the point.
Haruhisa Tatsumi is the onmyouji sent to investigate, pulled into the case because the local police are too overwhelmed to handle it themselves. He can also walk through the building’s miasma without it touching him the way it would anyone else. He works under Japan’s Bureau of Divination, and that resistance to curses is less a superpower than a job requirement. It is the specific reason he gets picked for cases too dangerous for regular investigators. There is something almost funny about how matter-of-fact he stays through the horror of it all, more tired procedural detective than genre protagonist reacting to the impossible.
The case itself starts with four tenants of an apartment building found dead, their organs removed, with no clear explanation beyond the miasma clinging to the scene. That single image does a lot of work early on, and it stays unsettling even after the story pivots toward comedy. Haruhisa’s investigation keeps circling back to it between the lighter scenes. Police involvement stops almost immediately once the supernatural cause becomes clear, leaving the case entirely in Haruhisa’s hands from that point forward.
Anneliese complicates that assignment almost immediately, arriving as a devil from England who has traveled to Japan for her own reasons. She strikes a deal to help Haruhisa investigate in exchange for a place to stay. She affirms that her skimpy default outfit relates directly to her nature as a descendant of Lilith, delivered with the same playful confidence she brings to teasing Haruhisa from the moment they meet. Solving the murder ranks well below flirting with her new roommate on her actual list of priorities, and watching that priority list win out against the case’s grim backdrop is where the comedy actually lands.
Fumi Kazuki wrote Kimagure Temptation, the same writer behind Silky’s Plus Wasabi’s earlier Nanairo Reincarnation. The mystery plotting here functions more as a frame for the central relationship than a puzzle built to catch anyone off guard. Anneliese carries the entire romantic side of the story as the lone heroine, with four other named characters rounding out the cast without romance routes of their own. That structure means the chemistry between Haruhisa’s grounded, work-focused personality and Anneliese’s persistent energy has to carry scenes on its own. It does, even in stretches where the mystery itself sits quietly in the background. Six different endings are available, including several bad ones, giving completionists a reason to revisit earlier choices without changing how the central mystery ultimately gets solved.
Character designer Kimishima Ao handles the art, and the split between styles is deliberate. Anneliese is animated through E-mote technology from M2, bouncing and shifting expression constantly rather than sitting still the way a normal VN sprite would. The rest of the cast use static CGs, all-ages scenes rendered plainly with occasional effects while the intimate scenes get full animation instead. Voice acting covers the entire Japanese cast except for Haruhisa himself, who stays unvoiced throughout. That choice puts more weight on Anneliese’s performance specifically, since she carries most of the vocal energy opposite a silent protagonist. It is a strange choice on paper, and yet it works. Keeping the reading experience grounded in Haruhisa’s perspective, it lets Anneliese be the one character who fills the room.
Silky’s Plus Wasabi and Syawase Works developed Kimagure Temptation, published internationally by Sekai Project. The same team built Nanairo Reincarnation and the Japan-only, still untranslated Akeiro Kaikitan, both set in the same shared timeline as this game. Sekai Project has recommended playing Nanairo Reincarnation first, though it is not required to follow what happens here. I found that true in practice. Nothing in this story assumes outside knowledge, but a few background details clearly reward it.
Two editions exist outside Japan. A 17+ edition through Steam and Sekai Project has the explicit content removed, while an 18+ edition through Denpasoft and JastUSA keeps it intact. A patch is available to unlock the adult content on the 17+ version if you already own it. The core mystery and the central relationship play out identically either way. Looking back at the grisly opening once the story had fully tipped into comedy, it clearly did the job it needed to do. It gave the demon-roommate silliness something dark to push against, and that contrast is why the lighter scenes land as well as they do.
Verdict
Kimagure Temptation stakes its opening on a horror premise grim enough to earn the name, and then spends the rest of its runtime proving that premise was mostly there to set up something else. Anneliese’s chemistry with Haruhisa, backed by full E-mote animation against his unvoiced, grounded presence, is what actually carries the game. The mystery plotting works best as a frame for that relationship rather than a puzzle in its own right. Six endings and a handful of side characters give it some replay incentive without ever threatening to outshine the central pairing. It sets up a horror story and delivers a sitcom about cohabitating with a demon instead, and that bait-and-switch is the most memorable thing about it.
