I enjoy it. Noborou is a blast of a character, he is extremely funny, witty, and extremely proactive, to the point of recklessness.
He even brings up the level of the side characters. His friends are the stockiest of stock characters, but that panel where they stand dramatically against the wind talking about cat lingerie is hilarious.
Which is kinda the point of a main character: he is supposed to make things more interesting by being around, otherwise why have the series focus on him?
