I’m going to be honest and say I didn’t think this show was a full length anime. If you look at the premise and the basic joke of each episode there is no real way of filling out the air time without over playing one joke until it’s no longer funny (these kind of joke shows need to be quick and snappy).
This show is about a perfect high school girl that transforms into a toddler (I know the joke is meant to be that when she gets home she is really lazy).
She has huge tantrums, cry’s in order to manipulate people, sneak sweets into the shopping trolley to the point you wonder if she has a concept of money and she even asks her brother to feed her……and you want me to believe she is an A* student?
There is a big difference between being lazy and being infantile.
