oh not that shit again. First of all, he didn't whine, he was slightly depressed, because he has feelings and all. Yes anon, humans have feelings, not everyone can be like Akagi, it would get boring fast. Also, his character developed, what was about time. And we are talking about 3 episodes here, bare with it.
tl;dr watch shounen animu if you want ass-kicking and don't care about the plot
