The five Nakano sisters suddenly found themselves in a world filled with primal magic and covert guilds. Instead of mastering their daily school routine, each sister had to unlock her unique abilities: while Ichika and Nino navigated the rooftop shadows of the capital as silent assassins, Miku and Yotsuba harnessed powerful elemental magic. Itsuki took the lead as the guardian of ancient runic lore. When dark forces threatened the city, the quintuplets proved that their strongest weapon was still their unbreakable bond.
