I only just stumbled across this manga series; I have very little access to manga other than the internet, living in the butt-end of nowhere as I do. I found it... different. It was certainly different how Hareta "caught" Regigigas, earning its respect rather than wearing it down and throwing pokeballs at it.
Though I did half expect Hareta to make a nest or something in the moss growing on its shoulder, considering how much time he spent up there.
I really enjoy DPA! because Hareta is such a sweet heart.
While he does catch some Pokemon through battling, when he confronts Legendary pokemon, he would rather befriend them than catch them, which I think is the reason for why Regigigas warmed up to him. Hareta is not afraid to battling WITH his pokemon, to the point where he can take quite a beating from a Pokemon and still somehow pull punches at them. He's a fighter.
Also, about that nest thing, it wouldn't surprise me if he did do that at some point. That would be adorable.
I still wish this series expanded on certain points rather than skip a lot like with the Gym Leaders. They could've fleshed out the characters much more.
