I just finished the first season and I absolutely loved it!!! Of the "slice of life" really light series this is the one I've liked the most.
I never thought I would like it this much.. At first I found animation a little different.. and found the characters, specially kenji like someone I would never like... I really didn't think it was going to be this good.... up till the first five minutes of the first chapter!! When I gave it a couple of minutes, I realized it was the funniest series I had ever seen.
Everything is so silly and many times stuff just doesn't make any sense, but believe me.. its great.. You must watch it. Also, in between the really silly stuff, there is a pretty interesting romantic story.. You get really fond of most the characters.. the girls are really really cute and Kenji is really... unlucky...
In the technical stuff the series is also good... Although animation is a bit strange, I ended up liking it a lot!! Opening and ending are great.. they tend to stick in your head... like those songs you just cant get out of your mind.. they are so cool and fun.. I guess what I liked the most is that I felt like a little kid while watching it... they make fun of the Power Rangers and a bunch of other animes... its so so so fun!!! Well.
I guess the main thing I wanted to say is that this is a top notch series.. and you should definitely watch it.
Im about to start the second term.. I hope to find it just as good.
