Nene Ōmori

Personality
Nene is far more aggressive than her permissive leader. Though she often openly disagrees with and occasionally disobeys Kunieda, she is still her faithful wingman, balking vociferously when Kunieda opts to leave the Red Tail and relinquish the mantle of leadership to her. She takes it nevertheless and soon proves to be worthy of it, gaining the confidence and trust of the Red Tail.

She hates men and doesn't like it if any members of the Red Tail are in a relationship with men. But that is most likely because part of the Red Tail rule is "No Men Allowed". The only man she doesn't mind is Kunieda's grandfather, since he was her and Red Tail's teacher.

Lately, she has been warming up for Oga Tatsumi as well. At first she hated him, because of Kunieda crush and her leaving Red Tail. However, after the run in with the MK5 and Miki, she starts to see Oga in a new light and almost accepts Kunieda's crush with Oga. This can be seen e.g. after Oga beats Toujou, when she respects him and even asks Kunieda why she wouldn't go and treat his wounds. But when Kunieda asked Oga to come out with her, she and the others (Furuichi excluded) thought that Kunieda was going to ask him out and told Kunieda to think things through. Like other members of the Red Tail, she also has a feminine side to her which Chiaki finds cute such as how terrible she is with playing online video games
