The story was very interesting and full of twists. There was plot development throughout the series but beware of fillers. The anime was so full of them and that's really annoying. I feel that the anime was unnecessary long (and that's not only because of the fillers which were at least 1 for every 10 episodes). The first season for me was like a build-up for the next seasons. It gives you time to get to know the characters a little bit better. The artwork was very well done. I really liked how the characters were drawn. There are a lot of sexy guys in this anime. The characters were perfect with their imperfections. I loved Hibari. His character was not only the sexy but well developed too. If you look deeper into the anime you'll see that his character is really kind despite the fact that he doesn't want to show it. The characters were all very well developed and very likable. The soundtrack is so amazing. That's a soundtrack which can lift your spirits up. I was laughing so much while watching this series so in my opinion this anime worth to be watched.
