Wow, you don't like the ED? Why? It's by Afromania, same author of Minna no Peace! This anime is really well done. The Animation is excellent and the story line has some tweak to it so it different from the manga which is awesome.
Back in Vietnam, when I was still in elementary school, I got slap or get cane when I was being a "bad boy" -.- Honestly, I feel punishment like that could help but it is just my opinion.
