Once again, sixteen Magical Girls have been assembled for a high-stakes challenge. Every three days, their Magical Phone pulls them into an RPG-like simulation where they have to work together to fight enemies, solve puzzles, and earn Magical Candy to advance. A staggering ten billion yen reward awaits them at the end—but only for the players who land the finishing blow. With such a tantalizing prize on the line, it's only a matter of time before the girls turn on each other—and if their hit points drop to zero, a game over will be the least of their worries...

Set in Akihabara in the spring of 1999, the story follows Nagomi Wahira, a bright‑eyed 17‑year‑old girl who moves to Akiba with a dream: to work at a maid café and live the “cute maid” ideal. She lands a job at the pig‑themed maid café “Ton Tokoton” (aka Oinky Doink). However, Nagomi quickly discovers that the maid‑café business in Akiba isn’t just about aprons and “moe” poses. It’s infused with cut‑throat competition, underworld machinations, and café rivalries that run deeply and dangerously.
