Bakuman. 2

Mashiro and Takagi start working with a new editor, Gorou Miura, as Hattori is assigned to another author. They must adapt quickly to his approach as well as drawing together with assistants since they must perform well on the Shonen Jack polls in order to not be discarded by the publication. Now that their work is being serialized, they must work even harder as they must satisfy an extremely demanding audience while competing with other talented authors.
