Submissions are still open!
Spider Crew:
they've all lost everything and found each other. They're from an Isekai story where a gaggle of characters including White, Sophia, and Wrath were reincarnated into a fantasy world. (SPOILERS ahead if you've seen the anime these scenes have not been adapted from the books yet!) I won't make you hear the entire synopsis but I think the most telling thing is when they were marching into war with a planned high casualty rate Ariel asked White (who didn't have a name before Ariel started calling her White!!) what their chances were of winning and she said 50% then she asked her the chances of everyone living and White knew she meant their inner circle and internally listed the others I mentioned above and first thought it was very slim and then said 100% and made sure that was true. White was entirely alone and "liked it that way" before incidentally grouping up with the others listed above and now she cares about them so much. The world is ending and she needs to use every bit of magic energy she can to fix it but still offered to expend some of that to send the other reincarnations back to Earth and didn't extend it to the other reincarnations! Its no small thing! But she'll take the risk and sacrifice it for them! Ariel first said she was only protecting Sophia and Merazophis because she thought it would get her on White's good side but that's definitely not all there is to it anymore!
Also who doesn't love a found family that includes elements of previously attempting to kill each other (White vs Ariel and later the group vs Wrath)
I know the submissions post said some people can be related but let me be clear: technically Ariel is White's grandmother. I wanted to include the puppet sisters as well (Ael, Sael, Riel, and Fiel) but they're Ariel's children and that would make the group 6 related and 3 not and it felt too imbalanced then. You don't get much of a "familial bond" impression off of White and Ariel when they first meet or until book 7 whereas the puppets feel like Ariel's children the way they look up to her and she definitely mothers them. And ironically they feel more like White's nieces rather than her aunts lol
Unfortunately they become a fam in the books only after where the anime currently leaves off so there's very little official art of most of them and none including Wrath who didn't join the group until Volume 9 I think? (and the anime stops at the end of book 6 right before the other 4 group up ;n;) but I found some things :p
