This series just seemed like a "short but sweet" anime at first, but after finishing it, it was a solid 60 episodes and "sweet" the whole way through. It has elements of comedy, drama, romance, action, etc. incorporating them so well. The way the series engages you from Furuichi's nonsense, to Oga kicking ass, then to Yogurty- it's just masterful.
As of right now this definitely takes the top
