Azusa is a third-year at the magic academy with no friends, no talent, and a body that draws far more attention than her spellwork. She cannot go home until she graduates as Top Maginoir - and every time the year runs out and she has not, April comes round again and she starts over. Eleven months stand between her and the top of the school, each with its own trial, in an academy full of people who have worked out that nobody is coming to look for her. The calendar is the game. April through February, each month a self-contained chapter with its own event and its own way to lose it.

Losing a month does not end the run - it changes what Azusa carries into the months after it. Lewdness, Chastity and Shame track what has happened to her, and the writing reads them back at you. Turn-based combat with a magic skill tree, equipment and a shop, a monster book, an in-school casino (high-low, poker and blackjack), 45 achievements, and a recollection room that replays any scene you have already seen. Two bad endings and a true ending. Non-consensual content throughout - that is the premise, not an occasional scene.
