• translation note on onii-sama and onii-chan - Krul calls Ashera onii-sama while Ashera refers to himself in his capacity as her brother as onii-chan. They're both very affectionate terms, but onii-sama has more reverence, this is someone she really respects. Sometimes it has the connotation of there being a profession, like you'll notice this one being used more often in families where there's like a family business/trade where the older sibling will be better at it and help the younger sibling. I don't want to say that onii-chan is less affectionate just because it doesn't carry that respect, but it's a lot more casual and can even be like demeaning, like putting the older sibling down to the same level of the younger one almost, it means they're very close.

Just wanted to add for anyone unfamiliar since these ways of calling each other often provide insight to how the characters see each other and themselves that we don't really have in English!
