"Anime adaptations of light novels are the popular thing nowadays but less than ten years ago the same could be said for visual novels. During this time frame numerous harem style romantic comedies were produced from that pool of source material and while a few of them can be fondly remembered, a large number of them have been forgotten. One such series which many have probably forgotten is Happiness! which has recently been given a subtitle only release by Maiden Japan. The question is, is Happiness! an anime that was better left forgotten?"
