Another year older means more responsibility at both school and home for Rin, Mimi and Kuro. Unfortunately for Aoki-sensei, that doesn’t mean that the precocious Rin is any better behaved; in fact, being in 4th grade seems to have made her even more determined to seduce her teacher! With the added stresses of a sports meet and her new role as class representative, the hyperactive girl still manages to keep a smile on her face and supports her two best friends through thick and thin. Will the classroom ever be the same again?
Satoshi Yabe is the newest employee at Kamohashi Elementary School. Wide-eyed and enthusiastic, he’s thrilled to finally be fulfilling his dream of being a teacher – but little did Satoshi know that he’d be assigned to class 6-3, a group that houses none other than the violent and perverted Marui triplets! Between the girls trying to hook him up with the busty school nurse, dealing with the unfortunate consequences of a hamster named 'Titties' and other misadventures, Satoshi’s dream of an uneventful school life has come to an end!
There are a lot of similarities between these shows. In particular, they both have 3 female protagonists 2 of which are VERY similar in each show, a dorky, male teacher who only means the best but gets into many situations where misunderstandings insue. There's also the female colleague and love interest. The main difference is that Mitsudomoe is a pure comedy based on misunderstandings while Kodomo no Jikan can get very suspect due to the comedic relationships between the young girls and their adult guardians.
