What is Homura's gender? In Sekirei, I am confused with Homura's Gender (Sekirei #06). I just can't seem to find out the logic of it.

Is Homura male or female?
From Wikipedia in List of Sekirei Characters:

It states under Homura:


  Homura (焔, Sekirei #06) was the self-titled "Sekirei Guardian" who protected unwinged Sekirei during the first two stages (this mission was given to him by Takami), usually from Hikari and Hibiki. Prior to being winged, Homura's power and gender were unstable. Even after his body started becoming female (called "feminization" in the manga), Homura continued to think and act as a man....
   Afterwards, Minato received the power to determine Homura's gender and mentality, but chooses to let Homura remain who he is for now
