Himeko's ordinary high school existence shatters the moment she finds a crown and puts it on. The accessory transforms her into a princess, dragging her into a chaos she never asked for. Now Nana, the actual princess, won't leave her alone, determined to reclaim what's rightfully hers. But Nana isn't Himeko's only problem. Leslie and Caren, a pair of scheming thieves, circle constantly, hungry to steal the crown for themselves and whatever power it holds. Caught between a legitimate royal, two criminals, and the mounting absurdity of her new status, Himeko just wants her normal life back. Instead, she's trapped in an escalating comedy of mistaken identities, failed heists, and the kind of magical girl chaos that doesn't care about your test scores or weekend plans. Every day brings fresh disasters as these groups clash over the crown while Himeko desperately tries to survive the collision. It's pure comedy mayhem for anyone who enjoys watching an unwilling protagonist get swept into ridiculousness.
