S01E01 The Solitary Cat
Train, better known as Black Cat, completes another mission for Chronos, and is informed of his next mission. Later, Sven is inside a restaurant, planning how to catch his next target. A parade is happening...
Chronos and the sweepers make plans to leave and go to the island where the Apostles of the Stars' headquarters is. Dr. Kanzaki, however, doesn't plan on letting the sweepers reach the island alive. He sends monsters to destroy the sweepers, leaving them with no choice but to fight before they can even reach the island.
The bounty hunter Sven is barely scraping by when he crosses paths with the Black Cat (a.k.a. Train Heartnet) and the young bio-weapon Eve. The three new companions will need more than luck to survive when they find themselves sought by both the Chronos Numbers and a Taoist revolutionary group called the Apostles of the Star.
