12 Best Harem Anime of All Time

Harem is a genre of anime that consists of polygamous relationships. While in some societies polygamous relationships are acceptable, it remains a taboo topic in most societies, where having multiple partners is even frowned upon. Different societies may have a different stance on the matter, but in the anime world, shows focusing on polygamous relationships have a huge fan following to the extent that they are divided into two niche genres — harem and reverse harem.

While the former revolves around a male protagonist with multiple partners, the latter focuses on women-centric stories where the main character has a multitude of male love interests. Although both of them are super entertaining, we would be focusing our entire attention on harem shows. Most of these harem anime are available for streaming on Netflix, Amazon Prime, Funimation, Hulu, and Crunchyroll.

The anime follows Naoya Mukai, a teenager whose romantic advances are rejected by his childhood crush Saki Saki until she finally accepts him as her boyfriend in high school.

But when his classmate Nagisa Minase confesses her feeling for him, Naoya can’t gather the courage to reject her and convinces Saki-chan to let her become his second girlfriend.

Ignoring the chaos and rumors around him, Kogarashi vows to help her find the secret that is keeping her attached to the world of mortals.
