Glad you like her! 

As to the skills, I did think about going with other things but I thought a sort of specialized approach early on might be best (also I couldn't think of more general skills). As to what overeating does, that one (and the other one) are pulled from that one isekai with the girl who reincarnated as a monster-spider, and I believe (might be misremembering) it allows for consuming things without issue as it levels up (since otherwise eating most creatures would be pretty impossible).
