Harem anime occupies a unique niche within the broader anime landscape, often drawing mixed reviews compared to genres like isekai and sports. Despite some critiques labeling them as mere escapist fantasies, harem series resonate with audiences, delivering engaging entertainment that offers a whimsical retreat from everyday life. As we look ahead to 2025, the upcoming lineup promises to enhance this genre significantly.
The coming year is set to unveil a diverse array of new harem anime and anticipated sequels. While not always in the spotlight, these 2025 harem offerings could emerge as unexpected gems worth watching. Here’s a rundown of what has been announced thus far.
It’s essential to note that stealth harem anime, which may not explicitly fit the traditional mold, will be included if they incorporate key genre elements.
Winter 2025
The Daily Life of a Middle-Aged Online Shopper in Another World

While not every isekai anime is classified as a harem, many themes within these genres overlap. In “The Daily Life of a Middle-Aged Online Shopper in Another World,”viewers meet Kenichi, a character who is magically transported to another world where he can shop online. This premise echoes the successful formula seen in “Campfire Cooking in Another World with My Absurd Skill.”
However, this upcoming Winter 2025 series also fully embraces the harem aspect, as Kenichi leverages his one-of-a-kind ability to cultivate a fulfilling life surrounded by multiple admirers and friends.
The 100 Girlfriends Who Really, Really, Really, Really, Really Love You Season 2

Among the most anticipated harem anime releasing in 2025 is the second season of “The 100 Girlfriends Who Really, Really, Really, Really, Really Love You.”Following a comedic and surprisingly heartfelt first season, the series centers on Rentarou, who discovers he has 100 soulmates—a situation he must navigate to prevent disastrous outcomes for them all. His quest embodies the quintessential harem protagonist.
While primarily a comedy, the series excels in developing distinct and relatable characters, ensuring that the female leads are not just typical archetypes but dynamic personalities.
Spring 2025
I’m the Evil Lord of an Intergalactic Empire!

In “I’m the Evil Lord of an Intergalactic Empire!,”harem and mecha unite in a fascinating blend. The narrative follows a protagonist granted a new chance at life following a grim existence. He must navigate his role within an evil imperial family, challenged by a Guide who has a hidden agenda, compelling him to embrace his darker side despite his inherently good nature.
2025 Harem Anime With No Release Season
A Couple of Cuckoos 2nd Season

“A Couple of Cuckoos”is considered a polarizing title, challenging viewers with its unconventional approach. As a comedy featuring flawed characters, the series offers humor by depicting a male lead overwhelmed by the antics of his co-stars—yet, it struggles with its romantic development, particularly as it progresses at a sluggish pace toward a meaningful resolution.
Chitose Is in the Ramune Bottle

Shifting gears, “Chitose Is in the Ramune Bottle”presents a more slice-of-life perspective. The protagonist, Saku, is charismatic and self-assured—departing from the typical timid harem lead. Focused more on friendships than romantic entanglements initially, the story involves Saku and five main female characters, each promising to enrich the narrative with their unique dynamics.
Rent-a-Girlfriend Season 4

As a standout entry in the harem anime spectrum, “Rent-a-Girlfriend”has drawn considerable attention, both positive and negative. Its unique premise has long established Kazuya’s affection for Chizuru as the ultimate destination, despite the comic misadventures he encounters along the way. Building on the success of its third season, characterized by an engaging movie plotline, Season 4 is likely to further captivate its audience while remaining divisive for detractors.
The Shiunji Family Children

From the same creator as “Rent-a-Girlfriend,””The Shiunji Family Children”offers a distinct but familiar tone. While lesser known, this upcoming harem anime could deliver a more traditional take on the genre, centering on a step-brother and his step-sisters. Viewers can anticipate a blend of relationship dynamics within a unique familial context.
