2026 is less than a week away, and as Peter-senpai highlighted, 2025 had some stellar anime. However, every day, there’s a new anime fan, and many veteran otakus don’t follow seasonal anime. That’s understandable. Life often gets in the way of our enjoyment. But knowing our dear readers may have missed some steamy fan service anime makes us lose sleep at night. So, we’re here to change that. We’re here to recommend the best fan service-filled anime of the year!
Great news! J-List has started a new sale for everyone, this time giving you 18% off on all “hentai” doujinshi, manga, anime and related items! Start browsing the sale items here!
Whether you like laid-back shows or enjoy romantic comedies, there’s something on this list for you. Fan service isn’t a genre; it’s a vibe. Every anime can have fan service. Sure, many people hate “needless” fan service, but you’re reading this on otakudom’s most cultured page, so you’re not one of those. So, use your end-of-year lull to check out (or rewatch) these sexy-ass shows!
2025’s Best Fan Service Anime — Makina-san’s a Love Bot?!
A few days ago, I was reading a story about how AI poses an existential threat to humanity. It bummed me out for a few days. My forlorn mood wasn’t due to knowing our species is doomed. Honestly, I wish that would happen sooner. My sorrow stemmed from the fact that we somehow skipped AI sex bots and went straight to Skynet. Of all the travesties humankind wrought, that is the most lamentable. So, I did the only thing an otaku can do when they’re depressed over not getting a sensual robot waifu: I watched an anime with a lot of fan service. I watched Makina-san a Love Bot?!.
Unlike the authors of the article I read, Eita Akutsu doesn’t worry about AI or robots taking over. The introverted nerd spends most of his time researching robotics. The only thing he loves as much as his machines is his school’s hottest gyaru — Makina Agatsuma. But his skills lie in engineering, not communication. So, Eita never approaches the eroppoi Makina. However, one day, Eita’s crush finds her way to him. As the meek robotics otaku comes home, he finds Makina waiting for him at his door. And the biggest surprise? She’s a badly damaged love bot!
Makina-san’s a Love Bot?! is a quick binge, as this fan service (and nudity)-filled anime is only 12 minutes long. OceanVeil streams the uncensored version of Kakushite! Makina-san!! which I can’t praise enough, because this is the year’s most oppai-heavy show!
Tying the Knot with an Amagami Sister — a Supernatural Binge
After the first episode of Amagami-san Chi no Enmusubi, I wasn’t expecting much. I certainly wasn’t expecting a fan service-filled harem with supernatural twists that would disturb me. This anime is one of the few things that has managed to dismay me. Because of that, I recommend this show every chance I get! But what is it about?
At an early age, Uryu Kamihate suffered the horror of seeing his mother die. Despite his constant prayers, after her passing, he found himself as the newest resident in an orphanage. As time passed, Uryu-kun quickly grew to resent religion and the belief in gods. In his mind, only people can help other people. The best way to do that is to become a doctor. With that, Uryu devotes himself to that goal. But despite Uryu’s determination, the constant noise at his orphanage eventually hampers his studies. Luckily for Uryu-kun, the Amagami shrine takes him in. But his new home comes with a seemingly impossible condition — he has to marry one of the Amagami sisters and take over the shrine. But with Uryu’s views on religion and ornery personality, his task isn’t a simple one.
At 24 episodes, Tying the Knot with an Amagami Sister is a full day’s watch, but it’s worth every second. The manga recently finished, so you can get closure by checking that out after. Crunchyroll streams this supernatural, fan service-filled harem.
There’s No Freaking Way I’ll Be Your Lover! Unless…
2025 gave me plenty of enjoyable memories, but by far, one of the best was Watanare. Every anime fan, no doubt, knows that even if you become a veteran, every year you find fewer shows that have the spark that drew you to the medium. That’s how life works: time dulls everything. Yet, every so often, an anime comes out that hits the same feels as the first batch of shows you watched. And for me, this year, that was There’s No Freaking Way I’ll Be Your Lover! Unless… It had everything I loved: a cast that’s not afraid of sexy time, plenty of fan service, lovable characters, and SSR entertainment levels. And I’m not the only person at J-List who loved this show; it was a staff favorite!
Watanare follows Renako Amaori, a shy introvert who, for reasons beyond my comprehension, decides that she wants to be a filthy normie. So, when she graduates from middle school, she enrolls in a high school devoid of people Renako knows. Then she completely reinvents herself to fit in with the “popular” girls in her new school, and it works! But her transformation works too well. To Renako’s dismay, she quickly becomes the target of all her friends’ romantic affection. And that gives us so many steamy, yuri, fan service scenes!
There’s No Freaking Way I’ll Be Your Lover! Unless… is available for free on the It’s Anime YouTube Channel.
KuraKon, a Fan Service-Filled Anime for Tsundere Enjoyers
I dislike anyone who doesn’t like tsunderes. In my eyes, tsunderes are perfect wife material; they love you, protect you (obviously not against themselves), have stunning looks, and dislike affection. I couldn’t come up with a better partner even if I tried. And since tsunderes still fill every other show, Japan and the wider otaku community agree with me. So, without a doubt, someone reading this is going to say, “Kashou, where are the tsunderes?! I need tsundere fan service!!” I got you, homie. I’m Getting Married to a Girl I Hate in My Class has a tsundere so loud that she’ll give you hearing damage if you watch this show with headphones.
Saito Houjou’s life seems to glitter with gold. He’s intelligent, capable, and will one day inherit his grandfather’s conglomerate. Or at least that was what he thought, because one day his grandfather gave him an ultimatum: marry the granddaughter of his childhood sweetheart or lose his future company. And while his potential wife, Akane, has looks that can rival a breathtaking star-filled night, Saito cannot stand her. It’s nonstop bickering every time they see each other. Yet as his and Akane’s futures become increasingly threatened, the two agree to a marriage. But they flubbed it. Their marriage isn’t a faraway endeavor; it’s happening immediately, and they must live together!
You can check out KuraKon on Crunchyroll.
