Rei is a first-year student ranked 128th, dead last at a sword academy. Each week you plan classes, training and dungeon dives, then climb the rankings by winning tournaments. Win the Sword Festival, and you earn a duel with Elda of the White Wing, the academy's top student.

The dungeon is a roguelike treasure hunt whose layout changes on every dive. Battles play out automatically by default, following the tactics you set, while you collect gear from chests and floor bosses and push deeper. When an enemy telegraphs a heavy attack, you can pause and make a move by hand.
