This anime is based on a 1999 radio drama about three very different girls: Akari, Yuki and Nozomi; going to see the concert of top pop idol Reika and by going to see this concert their lives are greatly influenced by it. Akari was raised in a very religious background, she is bright and cheerful and a big Reika fan. Yuki is an independent girl who ran away from her home in Hakodate. She is working in the concert hall of Reika's performance. Nozomi is the daughter from a wealthy family in Kobe. She's got one of the VIP seats at the concert. The three girls are so inspired by Reika's performance, that they all enroll in the Akiba music school and endeavor to become pop idols themselves. (Source: AnimeNfo)

When a gigantic, unearthly monster suddenly looms on the skyline of a Japanese city, the expected occurs—the Japan Self-Defense Forces roll out the tanks while the public panics. Nobody knows what it is or where it came from, but Yuki, a bold and inquisitive teenage girl, has a secret but might be a useful clue. Her friend Tetsu has been clandestinely caring for a bizarre creature called Cenco, which will soon prove itself to have some remarkable, even impossible characteristics. Another teenage boy, a stranger with some mysterious link to the monstrosity attacking the city, shows up, and his unwelcome interest in Tetsu's pet snuffs out any doubt of a connection—and lights the fuse for the coming battle.

In the year 54 AD, 15-year-old slave fighter Cestvs desires one thing—an escape from his violent life. It is the wish Cestvs' owner has promised to grant him, but only after he wins 100 battles. However, Cestvs quickly comes to terms with the fact that, as a slave, his life is expendable. After the death of his friend, the possibility of freedom is the only thing keeping him going. With a burning ambition to attain it, Cestvs embarks on a journey to earn himself back, even if it means fighting other slaves for the entertainment of the public.
