When she said she liked cats, I expected it to turn out she really does like cats, as a meal.
Interested in grandma "hating adults". Considering the theme, it is easy to make a guess why, but I would like to know the story behind that remark.
I really like the reminder that Itou doesn't forget she is a monster, and in fact likes and envies exactly that artifice of being normal.
Which is an interesting little tension so far between her and her grandma, who stridently has abandoned all semblance of normality, which Itou feels a bit embarassed about. That scroll of "be yourself" likely comes from grandma who wants her to encourage to do that.
