Homerarete Nobiru SR Shoujo-tachi

SR girls are one of a kind, and that's the problem: being the only version of yourself in existence leaves you with no idea who you actually are. Takatoo Mitsuki finds out he's one too, right after getting yanked out of his part-time job by a stranger and dropped at Saint Marianne Girls' Academy.

The headmistress doesn't ease him into it. His old job is over; his new one is helping the school's SR girls figure themselves out by growing closer to them, whether he wanted the assignment or not. It's a premise played mostly for laughs, with a horror streak running under the harem setup rather than replacing it.

The game runs as a visual novel: read the academy's dialogue-heavy scenes, get to know each girl one at a time, and move through the harem routes as the relationships escalate into voiced, illustrated scenes. Early releases shipped with truncated text that made some of it hard to follow, and the update history is mostly about fixing that rather than adding new content.
