The Colosseum is one of the New Seven Wonders Of The World and a symbol of the ancient Roman Empire. It was once used as a venue of entertainment for animal fights, competitions and drama performance. There were numerous chambers and tunnels beneath the arena to hold gladiators and keep beasts, all of which were for the entertainment of nobles. A gladiator who has fought for freedom has left his last wish in his helmet after his death. By chance, Solar obtains the legendary helmet with mysterious power and a series of strange events develops.
