Throughout history, shrine maidens armed with swords have battled 'aratama,' mysterious beings that pose a threat to humanity. These school-uniform-clad young women, known as 'Toji,' constitute a unique division within law enforcement called the 'special religious service police squad.' Endowed by the government with the authority to wield swords and act as public officials, these Toji are educated in five academies nationwide. Annually, the elite Toji from each school converge in a spring tournament, prompting intensive training as they strive to enhance their abilities and fortify their prowess.
