Wasn't Iroha a (decidedly female) Sanrio character before she was a Vocaloid? This isn't a situation like Gackpo, Piko, or YOHIOloid, where the character is based on the voice provider and can be thought of as sort of a fictionalized version of them. There's no reason to believe Iroha and her voice provider share anything but a voice, and a voice in isolation does not necessarily carry any implications of gender. (I hope that made sense. I am attempting to provide additional rationale for Iroha being considered a feminine Vocaloid.)
