In an otome game, a dimension devoid of deities faces a perilous threat from Nightfly O'Note, an enigmatic extraterrestrial from a crimson realm breaching through the crimson barrier Scared. To combat this menace, humans establish the LAG defense agency on the Ryūkyū Islands. Despite the valiant efforts of the anti-Nightfly O'Note unit Scared Rider, they suffer decimation five times. The formation of the sixth unit, Scared Rider Xechs, comprising five young men, coincides with the abrupt cessation of the Nightfly O'Note invasion. With their adversaries vanquished, the SRX members grapple with mundane life, finding solace by forming the music band Odd-l's to combat their ennui. Meanwhile, a young woman assumes the role of instructor and commander at LAG, heralding a new chapter for both her and the SRX. As they navigate this new reality, the lingering question looms: 'Is that directive driven by love or by impending doom?'
