Ok so. This is Bunny. Just "Bunny". He/him.
He joined the crew of S.S. Houndstooth because of a bad breakup. He broke it off himself, but it was because of his own reservations and insecurities, so he felt the need to run away, at least for a while. Now he's stuck in the middle of nowhere!!! :D
Upon first wandering into (and eventually out of) Nariko, he's skittish and unsure, but over time, mostly catalyzed by the discovery of his and the other inhabitants' immortality, he starts to care a lot less about consequences.
He's agreeable, but comes across as cold or even cruel; in truth, he still has plenty of his original kindness and meekness left, but has buried it under spite towards his previous failure in relationships. He's in a constant struggle with this self-made artificial roadblock in the face of his need to have a live with meaning (and meaningful relationships). At least it means he'll do pretty much any mundane task or mercenary work for next to nothing in return, just for something to do that means something (especially to someone else). He'll claim he's just bored, of course.
Oh. And Chips is there too. I wasn't going to initially include him, but then I realized him being in the paintings would be strange if he wasn't, SO technically he's there. Roaming around Nariko and its outskirts like a ridiculous cryptid. I tried to imagine how he got there, and so this is what I visualized. He may have stowed away on Houndstooth specifically, or even a different ship entirely....whatever is funniest <3
