Once mocked as the weakest heroine, Momose Rei of Aura Pink gradually grows stronger and evolves into a true warrior through facing adversity. However, intoxicated by her newfound strength, she recklessly drags her teammate, Kuchiguchi Futaba of Aura Yellow, into battle, resulting in Futaba's injury. Despite being reprimanded for her mistake, Rei continues to act on her own judgment. Fighting as Aura Pink, she endures countless wounds in battle against monsters and defeats the villains of Derujion, celebrating her victory with a triumphant "Ore!" But before her stands a new enemy—another trap laid specifically to target her. In the end, she is led once again toward defeat... [BAD END]
