This TV series, which aired on Fuji TV and features both 3D and 2D animation, was based on the two manga series Kentō Ankoku Den Cestvs (1997-2009) and Kendo Shitō Den Cestvs (2010-present), both written by Shizuya Wazarai.
The story told is that of Cestvs, a 15 year old boy, orphaned and enslaved in Rome in 54 CE, who has been trained as a professional fighter by Zafar and who seeks to obtain his freedom by winning one hundred battles. He comes to the attention of the young new emperor Nero, who solicits the support of both Cestvs and his fellow slave fighter Ruska. There is also a storyline that includes a fighter from Pompeii named Emden who seeks to win over Sabina, the richest woman in Pompeii, through his abilities in the arena.
