Yeah, it's quite weird how Kuro's personality in the recent chapters is a lot more hostile than in chapters 149-151 of the original manga (he did not become furious about not being able to kill Khameleon, unlike in chapter 71 for Rito). He also says he was already planning to kill all the bioweapons before he got the request, so that leaves me wondering if there are more weapons like Yami, Mea and Nemesis out there.

I personally believe Kuro is human, but is extraterrestrial. It's likely life on his planet developed like Earth's, resulting in aliens that are more or less like humans from Earth. Same goes for characters from Mikado and Tearju's home planet.

By the way: his gun makes him so OP.
