Similar in style and themes. Both feature heavy action in a gang-controlled city, with groups of criminals not tied to any particular gang of mafia and work freelance.

While it may not be apparent at first, then overall feel of both these works can be compared in many ways. First of all both these manga aim for a fully real setting and story. Both feature heavy drama and relationship struggle, with emphasis on the character's way of dealing with these obstacles. In both you find a main male and female protagonist who struggle with some aspect of their life, and you also get a smaller but meaningful insight on the rest of the cast's struggles. Overall if you enjoy real and relatable settings, with a good dose of drama, i recommend you check both of these out.

Both feature an out of the closet otaku who find themselves in a harem romantic comedy with gaming themes. Both show's artistic approach is slightly different from the norm. Kami nomi with its pop out characters, and SaeKano with its colour contrast and attention to detail when it comes to female movement and gestures.
