Ecchi anime may reign supreme in terms of fan service, but if there’s a close second, it has to be harem anime. Harem anime is one of those magical things that most people can’t be neutral about. They either hate it or love it. And even people who love it will have a list of complaints about the genre. Even I do. There are harem protagonists out there denser than TON 618, and much like TON 618, they zap the light out of my life. Yet despite my complaints, you can bet I’ll check out every harem anime that a season has to offer. And if you’re like me, and you’re wondering where to watch all the winter 2026 harem anime, here’s where to go and what to expect.
Tune In to the Midnight Heart — Crunchyroll
What would you do if you heard a voice so beautiful it enraptured you? For Arisu Yamabuki, there was only one answer — confess his love.
As a well-off child from a wealthy family, Arisu spent his life striving for success and perfection. No matter the challenge he faced, Arisu met it with a smile. All the while, his greatest solace was the voice of Apollo, a late-night radio host. But, while Arisu managed to convey his feelings to the radio host, she unexpectedly stopped broadcasting and was lost to him. Arisu searched for her, despite knowing only Apollo’s voice.
Years pass, and his search proves fruitless. But during Arisu’s first day in high school, the unexpected happens. Through the school’s intercom, he hears Apollo’s voice once more. But another problem opposes Arisu. While he knows that the girl he’s held affection for so long is in the school’s broadcasting club, all four members of it sound eerily alike.
This winter 2026 harem anime is based on the manga by Masakuni Igarashi. Kodansha’s Weekly Shonen Magazine has serialized Mayonaka Heart Tune since September 2023. Crunchyroll will simulcast the series on January 6. Studio Gekko, known for Jinsan Baasan Wakagearu and TenPuru, will animate the series.
Tune In to the Midnight Heart will be available throughout most of the American continent (except Cuba), Africa, Europe, Southeast Asia, the Middle East, and the Indian Subcontinent.
Chained Soldier — HIDIVE’s Only Winter 2026 Harem Anime
Chained Soldier makes its triumphant return this winter. And with it, we’re getting a whole new roster of lewdable waifus (#YakumoEzoBestGirl; Disagree? Square up)! While I can confidently say that the second season of Chained Soldier is one of the most anticipated Winter 2026 harem anime, statistically, someone reading this has yet to watch the anime. So a synopsis is warranted.
Yuuki Wakura is a man after this writer’s heart. Where others worry about mundane things like long-standing careers and promotion chasing, Yuuki worries about living an ordinary, mundane life. Yet the world that Yuuki lives in is anything but mundane. Interdimensional portals regularly open across Japan, leading to desperate clashes for survival between ultraterrestrial beings and humanity. However, for Yuuki, those battles are a world away; after all, only women can fight against those otherworldly beings. But when Yuuki is transported to the other-dimensional world of Mato, suddenly his life loses all mundaneness.
Chained Soldier (Maho Seihei no Slave) adapts the web manga by Takahiro (author) and Yohei Takemura (illustrator). Shueisha’s Shonen Jump+ has serialized the manga since January 2019. J-List favorites Passione (Love Flops) and Hayabusa Film (Nukitashi the Animation) will animate Chained Soldier’s second season.
Do you remember when HIDIVE was available globally? I sure do. But those days are mere memories. If you want to watch this Winter 2026 harem anime legally, you need to live in Australia, the US, Canada, Ireland, the UK, or New Zealand. The series will simulcast on January 8.
You Can’t Be In a Rom-Com with Your Childhood Friends! — Crunchyroll
The concept of childhood friends is foreign to me. If you’ve been friends with someone for more than a year and you haven’t confessed, it’s not love. The whole of Japan disagrees with me on that, as childhood friends in harem anime are like ice crystals in a glacier. And in this Winter 2026 harem anime, childhood friends are on full display!
Where most guys are lucky to have a single kawaii childhood friend, Yonosuke Sakai has two! And to his dismay, they both grew up into full-on bishoujos! Why is he dismayed? Yonosuke likes both of them, but instead of having Rentaro’s balls and getting more than one girlfriend, he fools himself into thinking he must choose one. Yet, unknown to Yono-kun, his childhood friends Shio and Akari also like him! Whether the trio wants their relationship to change or not, a love triangle forms.
Tezuka Production, the studio behind The Café Terrace and Its Goddesses, will animate this Winter 2026 harem anime. The upcoming show is based on the Osananajimi to wa Rabu Kome ni Naranai manga by Shinya Misu. Kodansha’s Pocket Magazine has serialized the manga since March 2022.
Crunchyroll will simulcast You Can’t Be in a Rom-Com with Your Childhood Friends!, starting on January 5. The anime will be available for the American continent (except Cuba), Africa, the Middle East, the Commonwealth of Independent States, and Oceania.
Which Winter 2026 Harem Anime Will You Watch?
