Neferpitou's gender is ambiguous. While Chimera ants only reproduce through a Queen, the Chimera ants born from mammals take on both physical traits and pronouns. While they lack reproductive organs, Neferpitou is still a unique case. Gender-neutral and androgynous characters often appear in shonen.  To put it simply, the sources on Neferpitou's gender are muddled and mixed. As many writings on Pitou's gender do, I will use they/their pronouns. They might be a murderer, but they deserve their preferred pronouns.
