Rumors always sound stupid until you are the one they whisper about. This game throws you into one of those sticky school legends, the “there is a satanic cult behind the gym” kind of bullshit, except you actually trip over the damn book they are using. Not a cute grimoire with sparkles, more like something that looks like it smells of old cum and candle smoke. You crack it open for a laugh, and the first thing it gives you is the power to make the class virgin blush so hard she almost creams herself in the middle of an “examination” scene where the teacher leans too close, her tits brushing your arm, and you realize the book is not just edgy goth decor. It lets you push people, twist their lust, nudge their fears, and at first you just use it for small shit: making your best friend text you late at night with “I had this weird dream, why were you watching me in the shower?” while you are literally watching him through some voyeur spell on your phone, zooming in like it is some cursed Pornhub live cam. The game plays like a mix of visual novel and sandbox, you wander around school halls, club rooms, that empty classroom behind the science lab where the “mystery club” girl hides her monster girl hentai doujins, and every choice you poke in the text gets a horny consequence ten minutes later. Sometimes it is just teasing, a milf teacher accidentally pressing her big ass on your desk while bending over the board, sometimes it turns into full on corruption, like you mark a shy futa class rep with a little symbol and next time you see her she is in the bathroom stall, stroking a throbbing cock that looks too heavy for her thin legs, biting her lip and mumbling your name.

The story pretends to be about this “evil power” and responsibility, but half the time I forgot the cult plot and just chased who I could break or save or both. You can go playful, using the book to make girls horny at the worst moments, like forcing a strict nurse to lactate during a routine health check, milk stains spreading on her white top while she clenches her thighs, then suddenly she is grabbing your hand and shoving it under her skirt, muttering how this is “for science.” Or you lean into full NTR stuff, using blackmail photos and the book’s little curse tricks to push a sweet romance into pure cheating. There is one brutal route where your “best friend” tries to confess to his crush under the cherry tree and you quietly tweak her feelings so she accepts, then later you drag her into a storage room and she is on her knees around your cock, choking and crying because she knows she is his, but the spell makes betrayal feel like a delicious punishment. The game loves mixing that hurt with the horny: a loyal girlfriend getting pounded by a big black cock you summoned from some “monster” page, your corrupted class rep in a gangbang bukkake scene with faceless students dripping on her glasses, the principal on her knees in the occult club room giving a sloppy oral exam as if it is normal curriculum. There is futa, femdom, crossdressing sissification stuff where the book flips your own body, giving you a fat futa dick for one route, soft tits in another, forcing you into a skirt while a female domination demon spanks you until you are hard just from the pain. One day you are fingering a shy monster girl by the pool during summer vacation, her tail curling around your wrist as she begs for creampie, the next you are watching a furry club president hump your enchanted sex toy in the empty gym. It is messy, horny, a bit mean, and the book never really feels safe; every time you use it to make someone moan louder in a titfuck or a footjob scene, there is that tiny line of text hinting that maybe the book is also rewriting you, turning a “regular student” into something closer to the cult freaks you laughed at in the first place.
