Started watching this 2 weeks ago, but forgot to watch anime till today, so I'm all caught up now (to ep 2 of this anyways) and I have to say this is gonna be one of my favorite new shows of the season, imo. Main character fits the bill as a "not completely useless" main, the girls are cute and its had some solid scenes so far. Pretty funny and entertaining.
