Black cat

Train Heartnet, reformed assassin turned bounty hunter, also known as Black Cat, comes to the aid of a troubled boy seeking revenge for the death of his parents and is forced to confront his own vengeance-laden past. Meanwhile, Rinset forms a shaky new relationship with an old enemy.

"Train Heartnet, also known as Black Cat, was an infamous assassin for a secret organization called Chronos until he abandoned that cold blooded existence... The Chronos assault team... find[s] themselves battling a beast created by nanomachine technology. Sensing danger, Train appears on the scene. But instead of taking sides, Train has his own agenda."--Cover p. [4].

At Sven's urging, Train finally reveals the details of his past--the nature of his relationship with Saya Minasaki, the details of his quitting the Chrono Numbers, and the cause of his violent hatred of Creed.

Reads from right to left. Train and the Sweeper Alliance make it to Creed's island hideout. However, the Apostles of the Stars are ready and waiting for them.

The final stage of the battle begins! Now that Train and the Sweepers have reached Creed's hideout, there is no turning back. But for Train, it's not about avenging Saya's death anymore. He is risking his life to capture Creed as a member of the Sweeper Alliance.

"After fighting their way to the center of Creed's Hideout, Train and Sven find their way blocked by the unexpected appearance of the Chrono Numbers. They're stopping the Sweepers so that they can take down Creed by themselves. But the Numbers find their own surprise--Creed appears to have become indestructible!"--P. [4] of cover.
