Neko have a reputation for being sly and sneaky. Maybe add a dash of the joker or trickster in there. They can be a lot of fun to be around. And a lot of frustrating. They enjoy confusing people. Whether gengineered or prosthetically enhanced, the majority of Neko just seem to love acting the way they think humanoid cats would act. Not that they’re always right. I’ve met many cats who think Nekos are stupid at best, or insulting to real cats at worse. I think it’s really self-selection in most cases. Somebody wants to have fun acting like that, so they modify or augment themselves to look like that, and then nobody questions when they act like that. Though I do know at least one person who was genuinely “born in the womb Neko.” She wears the stereotype like a glove.
