かぐやとみつき (ワンパンマン オリジナル)

These are two original characters I've made for the One Punch Man series, Kaguya and Mitsuki. They're twin siblings and childhood friends of Sonic and Flash.
Kaguya's a female, while Mitsuki's gender wasn't determined, so if they're a boy or girl, it's up to you to decide
They seem human, but they're actually monsters
