Ayako's tits are fantastic. That's the first thing that stuck with me after closing the browser tab, not the whole amnesia plot or the demon hunting. The 3DCG models have that specific late-2000s Poser look, you know the one? Slightly glossy skin, hair that doesn't quite move right, but the artists clearly spent all their polygon budget on the curves. And honestly, respect. There's a scene early on where she's just... touching herself, lost in a memory she can't grasp, and the way the light hits her is more compelling than half the mystery.
The point and click stuff is basic. Find item, use item, talk to the ancient demon Rin who has a "mysterious agenda" (read: wants to get in Ayako's pants, probably literally, since it's a demon). Yumi, the lost love, is there for the lesbian content tag, and it's sweet in a melodramatic way. But the mind control tag is where it gets properly fucked up. Yomi's influence isn't just amnesia, it's a creeping corruption. There's a sequence where Ayako is convinced she's just a normal office lady, and the cognitive dissonance is played for some genuinely unsettling eroticism before it breaks into a sex scene. The oral sex isn't just thrown in, it's often tied to power dynamics, Rin taking advantage of a confused moment, or Yumi trying to ground Ayako in sensation.
Complaint? The UI. Clicking on a tiny, unlit corner of a Japanese-style room to find a key while the camera refuses to pan smoothly. Felt like I was fighting the game more than any yokai. The multiple protagonists thing is undercooked too, you mostly just watch Ayako's mind unravel. But then you get a scene where Rin, in full demon form, uses its tongue in a way that made me forget the shitty inventory system. For the player who misses when hentai games were janky, horny, and took their dumb mythology seriously, this scratches an itch. Just don't expect it to be polished. It's a raw, lewd ghost story.
