Content Warning! This game contains:
Sexual content - Nudity, explicit consensual sexual acts between adults, including: vaginal sex, anal sex, oral sex (blowjob, cunnilingus), boobjob, handjob, masturbation, face sitting, threesomes, lesbian acts, creampie, facials, sex toys.
Fetish content - Bondage (kinbaku) portrayed as consensual between adults, armpit fetish, panty handjob, thumb sucking, exhibitionism (sex performed in front of consenting adult onlookers), voyeurism, sex in open spaces, harem.
Sensitive themes - The game features a supernatural curse that compels the protagonist to engage in sexual activity to survive, which constitutes a form of supernatural coercion on the protagonist. One scene involves playful resistance dialogue ("tsundere" trope) during a consensual encounter, where a character verbally resists while physically and willingly participating. This may be interpreted as dubious consent. All sexual partners in the game are enthusiastic, willing adult participants. The game does not depict sexual assault, rape, or non-consensual sex.
The game also contains mild depictions of fantasy violence (combat against monsters and a demon queen), strong language, some eerie scenes, and narrative themes of mind control used in a non-sexual context by the antagonist.
