Why is she acting like an actual 2 year old? If you told me she was a regular child I wouldn't question it at all. If you're going to have a child protagonist that's a reincarnator, why not at least make them a middle schooler or something? Idk, maybe make them a fan of isekai so they're genre savvy on the stuff and they're a bit smarter than the average person.
Also, about Rudoviku, this is just my guess but maybe Ludvik would be a good transliteration? That was my initial thought when reading the name.
Also, does this have a novelupdates page? I figured this was a novel considering it has a different author and artist and the official raw page does describe it as a Syosetsu novel adaptation. Can't find anything by searching on NU though.
