This chapter was heavy on Elizabeth faces. Not complaining I loved them, specially the "loli of judgement" in page 24.
The novels have no flashback so the knight oath was only narrated briefly second hand. Nania and Elizabeth parents are original designs by the mangaka takano itsuki and not by the illustrator sameda koban.
I liked this change from the novels, after all I am left feeling that I would also want to serve such wonderful loli. Its easier to understand why Nania doesn't want to part ways, after all Elizabeth is special because her father educated beyond her noble status.
