Return of Rome's God of War 24

Set in ancient Rome, this 40-episode historical drama follows Tiberius, formerly Primus—the undefeated champion of the Roman Colosseum. After his mother is murdered by the brutal underground Cult of Mars, he swears a three-year oath to lay down his sword, hide his identity, and work as a lowly slave in a small gladiatorial ludus, all to protect his younger sister Julia.
