Can a story whose ending is settled in advance still pull a reader to the last page? "Inma-tachi no Yuugi ~Ittara Owari no Isshuukan~" answers that problem through allocation.
A dream-demon who attends school as a human is marked with a seal by a higher-ranking incubus and bound to a wager: hold out for one week and she wins. It is a succubus story of non-consensual training and defeat without a reversal. The wager plays out in dreams, but its effects reach into her days.
The craft lies in how the subject of teasing is laid out across a seven-day timetable. Each day's accumulation is paid back at once on the last night, and readers on both stores see a book that gives its pages to the process rather than the outcome. The protagonist's refusal to drop her defiance, still plotting a counterattack in her head to the end, is what keeps that design taut.
The circle Yajirushi Key was active from 2016 to 2025 and left thirteen titles. It returned again and again to plots in which a protagonist is defeated inside a game or a fairy tale, and this book is where that line arrives. The art is by Hoshina Meito, the story by Yoha.
The store's "no reversal" tag announces the shape of the ending up front, and readers choose it knowing that. Its reception can be read as inseparable from that culture of tags. Official editions circulate in ten languages counting Japanese, and it stands 28th among doujin works.
