It's a spoiler if you haven't read that far, but Focalor appears in Chapter 215 in human form and is quite clearly male. The sillouhette of Sinbad's Djinn was drawn very early on and Ohtaka may not have finalised all of their designs at the time, or had a change of heart at a later date (the same occurred with Astaroth).
