Koukyoushihen Eureka seveN, Deadman Wonderland Recommendations
Fantastic Jinsei Kataoka x Kazuma Kondo works that are a mix of several different genres (sci-fi, drama, action, supernatural, tragedy, psychological, some violence, some romance). Both are serialized in Shounen Ace, but are surely more mature and interesting than most shounen series. <br/> In both the protagonist is a kid with a monotonous life, who suddenly encounters a strange girl, and sees his life change drastically. <br/> Both series have exciting plots, the same amazing art, and similar characters.
