This powerful machine creates energy from the sky and now lies in the centre of an artificial, man-made island called as Blue Island. On another such island named Izu Ōshima, a girl named Akane Isshiki lives a peaceful life with her family. Her grandfather Kenjirou is a smart yet eccentric scientist who is also the inventor of the Manifestation Engine. Because of this, the world has entered a new era of peace. However, this peace didn't last for long.

Suddenly without warning, an alien force known as the Alone (アローン Arōn) attack and invade Earth. Their prime objective is to destroy the Manifestation Engine so that they can send the world into chaos. Despite the human military forces hitting them with all they've got, they prove to be no match to the Alone's immense power. Just when all hope seems lost, Kenjirou gives Akane a special key which will allow her to access the Vivid System (ビビッドシステム Bibiddo Shisutemu), the only thing that can defeat the Alone.

Now donning a Palette Suit (パレットスーツ Paretto Sūtsu) and possessing abilities unlike anything she ever imagined, Akane fights to protect the world from the Alone. She also recruits her classmates Aoi Futaba, Wakaba Saegusa and Himawari Shinomiya to join her in the fight. However, a mysterious girl who is planning to foil their plans is working secretly behind the scenes.Characters
