So, I’m not entirely sure why I was drawn to this Ask, but I kinda liked the idea. I’d never considered doing anything with Mito that wasn’t focused on Gon and/or Killua, but once I thought about it it made sense. Surely she has a life and connections outside of Gon and reading his letters. Now, I think there’s a chance the Asker here meant to have Mito answer from the perspective of the Studio, maybe have her bring in someone from another series. However, I’d previously had Gon imply he used to fuck older women around the island before the start of the series, so I thought it’d be fun to have “canon” Mito answer, with a random woman in the same vein. You can’t really see her partner here, but her look is based off an extra we see in the opening of the first episode, when Gon catches the big fish. She’s just some slut Mito’s got eating her out, no one we know, but I kinda like that.

In case it’s not clear by the hair, the girl being “shared” by Gon and Mito here is Caulifla. I’m not good at explaining why some pairings make sense to me, but I thought she’d be a fun one to stick in this role (also I haven’t drawn her in a real long time, despite thinking I’d be drawing her a lot when I first met her). I don’t have too much to say about this answer, I’m afraid, but I think the pic and text themselves about cover it. ^_^
So this is a case where the character’s answer is kinda based on how I handle them in my work… Aunto Mito is a character who I like. I enjoy drawing her, but like the question mentions, it’s been a while. I only drew her once for a One-Shot comic back in March 2017. I haven’t drawn her since just because, well… I don’t have any good ideas for her. All I’ve got is pairing her with Gon and/or Killua, and I just figure people will get tired of that. So that’s why she says she likes to keep to herself. In the anime one of her roles is to read Gon’s letters, which serve as recap episodes, and I like to think she still gets to follow Gon’s career in the Near Hentai Studios. I don’t know if he still writes out full letters, but I’m sure he tells her all about his shoots with Killua, or the work he’s doing right now with the Freeman boys, or what have you. It’s also easier for him and Killua to visit when they’re not shooting content, since they all live in the same big studio complex, right?
