I'm a bit confused about it, especially the following dates:
- When was the big battle featuring the Demon King and the Hero King (and, apparently, "a young swordsman Hina Maxima")?
- When was Hina knighted in Biscotti?
- When did she meet Yukikaze? Was it before or after she was knighted?
- How old are actually Maxima siblings and Yukikaze?
Thank you very much!
