crona (soul eater)

Character from Soul Eater. The meek child of the witch Medusa Gorgon and the product of her experiments with black blood, Crona is fused to the demon sword Ragnarok, which berates and abuses Crona without mercy.

Crona's gender is unknown though there are hints on either side. The English dub settled on using male pronouns rather than call Crona "it" out of respect, though Medusa pointedly never refers to him/her as such.
