The storyline of Hero Tales isn't really anything special. A used-to-be nobody kid named Taitou finds out that he's actually the incarnation of a star. When he gets too angry he gets out of control and only his sister can stop him from destroying himself. I don't really want to explain it here I'm too lazy but I'll just say it disappointed me coming from Hiromu.
Taitou gets really obnoxious around the middle of the series and is so whiny it made me want to stop watching. I almost did stop but I had to keep watching to see if it got better. It did for a little bit but then went back downhill. The final fight is pretty lame and ends in the stereotypical anime fashion( if you know what I mean). I most certainly won't be watching this series again but it's okay to watch through once.
