Good chapter to make it clear that Raphtalia is still a child, even when her size and level is bigger.
Btw, i would be disappointed if Kizuna reveal herself to be mean. She was saved from that labirinth, even cried.
And Naofumi even if feeling she is suspicious, he should be more chill and kind with her. He is really a stupid brat, acting rude to cleary show his lack of trust even if it is not only useless, but the worst strategy possible, since he needs her help as a guide. The Anime Naofumi is 200% better than manga, because they fixed some of his behaviour, in special in the Bitch judgement for example.
