So far, I don't like him...
He's too carefree, too laid-back to be a squad commander. He needs to be more take-charge, more determined and more authoritative. I don't think I would follow a commander like him in a war. He should be traveling from place to place, looking at plants and animals instead of leading a military squad.
I haven't played the game, so I can't make any comparison there, but so far in the anime his character is not very impressive.
