25 Harem Anime That You Should Watch in 2023

Harem is all polyandrous or polyamorous relationships. These relationships mostly have a male character being swarmed by many female characters. In the case of a reverse harem, the scene is exactly the opposite.

In this post, we have curated some of the best harem titles. We will skim through old harem classics as well as new harem anime titles.

25 Best Harem Anime

For me, Tenchi Muyo! was the anime that kickstarted the harem genre.

Keep in mind HRM titles don’t mean the characters should have a romantic relationship. Also, a narrative with three individuals can’t be considered a harem. It is more of a love triangle.

But such stories are considered taboo in many regions, and the following titles aren’t appropriate for all age groups.

So proceed only if you are 18+.

25. In Another World With My Smartphone

in another world with my smartphone

It all started when a stray lightning bolt from God hit Touya Mochizuki. As an apology, he granted him a wish. He would let Touya live in a fantasy world that has its own exotic rules.

Touya accepts the offer but tells God that he will be bringing his smartphone along with him. And that’s how the story begins and narrates his encounters with exotic girls and his chances of having a romantic relationship with a few of them.

It might not be the cream of the crop but a fun harem to watch. Also, this is one of those harem anime where the MC marries all.
