Question: okiku is a man one piece?
Answer: Although he is male, Kikunojo says he is a “woman at heart” and so tends to act effeminately. In truth, there were many things hinting at it: The clearest sign of Kikunojo's gender is him referring to himself with sessha (拙者 or せっしゃ?), an archaic form of “I” used by male samurai. Kiku is wearing a Hannya mask.
