At first Hayate the Combat Butler by Kenjiro Hata and Sayonara, Zetsubou-Sensei by Koji Kumeta might not seem like manga with a common ancestry. The sense of humor and storytelling is quite different in both manga. Hayate has a very traditional design for a comedy manga in Shonen Sunday where as Zetsubou-Sensei is very stylized. But when we realize that Kenjiro Hata used to be an assistant to Koji Kumeta we begin to see greater similarities in their styles. When we look at, Katte ni Kaizo, a manga they both worked on together we can see how Hata was influenced by Kumeta. Hata’s work on Heroes of the Sea Lifesavers is clearly influenced by his mentor. Hata would go on to develop his own style in Hayate while Kumeta would further continue to refine his own style in Zetsubou-Sensei. I have compiled some samples from each manga to help illustrate this evolution.
