Black Cat

Black Cat is a story that revolves on three characters especially the man named Train Heartnet. He was rumored to be a legendary assassin, the "Black Cat". Now, we know where the title gets its name. The Book contains twenty volumes and in each volume, a number of chapters (averagely 9.25). I prefer the manga than the anime because the manga shows a cooler ending than the anime. The anime gets weird as it goes.

The world of Train Heartnet is capturing criminals, meeting with other sweepers (a.k.a. like bounty hunters), eating different kinds of viands, and saving the world.

It is a comic book that combines all of the genres to bring the satisfaction of the book to the readers and to itself.
