Vividred Operation - S01

For five years, the Manifestation Engine on Blue Island has solved the world's energy problems. On the nearby island of Izu Ooshima live the cheerful Akane Isshiki, her reliable little sister Momo, and her grandfather Kenjirou, one of the Engine's inventors. Their peaceful life alongside the powerful creation seems like a dream, until mysterious beings called the "Alone" appear, bent on destroying it. When the military fails to hold them off, Kenjirou gives Akane a special key holding the "Vivid System," which lets her fight the Alone. Together with Aoi Futaba, Wakaba Saegusa, and Himawari Shinomiya, Akane and her friends join the battle against this unexpected enemy as humanity's last hope.
