Black Cat (2005)

過去を背負って生きること――それは自由への近道。

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.
