Seelentau wrote: No idea who Sho and Judai are, but as I said, it's usually used for superiors, older brothers are normally called (o)niisan. The difference is that oniisan is familiar, aniki is not. Same age. And Sho is higher rank in the end, but Judai had way more skills, so that kinda explains it.

As I said, we likely won't be getting more information about their status and not to say they're siblings despite them calling each other sisters would be even more speculative. We have one argument (the honorific) pro and zero arguments contra this case. But saying that they are could also turn out to be false. Either way, as Norleon said, to avoid each side being wrong in this case, a Trivia notice is the most we should do.
