Yea... I think you should either check your eyes or your memory... Cos if anything, she's incredibly mature for her age. Her ways may be childish but that's normal because HEYYYY SHE'S A CHILD .. A LEGIT CHILD (not a transmigrated nor reincarnated adults ...) please.... Keep your foolish opinions to yourself if you cannot understand what's happening just because we are fed with adults playing child isekai over and over. This is practically a hidden gem.

One of the least intelligent FLs ever. Being happy about ruining her father's business, only feeling guilty about using the sword he made for her, but nothing else, then not sparing a single thought to how her dad feels not having any business and perhaps running out of money (I mean she didn't know who her grandfather was either, after all) and how this is likely forcing him down the path she wants to avoid in the first place, anyways, makes her a boring and cliched child character.
