4 min readThe joke never turns on him
I kept waiting for the joke to land. Not a vampire gag. Those arrive on time in Babanba Banban Vampire, Netflix's anime import.
I wanted the premise to admit it was sending up the trope it is hugging. Ranmaru is a 450-year-old vampire hung up on the "purity" of 15-year-old Rihito. He vows to guard the boy's virginity until 18 so he can drink "18-year-old virgin blood."
The logline reads like a dare. How far can you push this before it stops being funny? Not far enough.
Episode one opens in a sentō, a public bathhouse, where Ranmaru works part-time, supposedly to keep watch after Rihito confesses a first crush. Nudity, collisions, slapstick anime has mined for decades. The bathhouse also becomes a stage for something less funny.
Ranmaru's obsession with Rihito's virginity is the plot engine. "I only settle for 18-year-old virgin boys," he says, hunger mixed with reverence. Played for laughs.
Common Sense Media did not laugh. The humor is "hard to actually find funny" when it sits on "an uncomfortable premise." The outlet calls Ranmaru's behavior "predatory grooming behavior," and it flags the show's lack of consent as a recurring problem.
The series knows it is poking a taboo. It treats that knowledge as a hall pass. Ranmaru frets over a teenager's love life like a helicopter parent.
The age gap, the power imbalance, and the sexualization of a minor get treated as punchlines. AnimeTrendz called the show "problematic and plain weird," and said the comedy "masks or underscores" the predatory undertones instead of cutting them open. That review is sharp on Ranmaru's "controlling nature."

Buzz & Rumors
Public reportsBehind the Fangs: What We Know About Babanba Banban Vampire (2025)
A centuries-old vampire clocking in at a public bathhouse to babysit a high schooler? That’s the absurd premise of Babanba Banban Vampire, the upcoming comedy anime series set to premiere in 2025. latestnetflix.com's take is that with a cast of heavyweight voice actors and a manga pedigree, the show is already turning heads—but details about its production remain frustratingly scarce.
A Vampire’s Side Hustle: The Premise
The series follows an immortal vampire who takes a part-time job at a public bathhouse to keep tabs on a wholesome teen until his 18th birthday. The twist? The vampire can’t resist meddling in the boy’s love life, leading to chaotic, comedic fallout 
. The setup blends supernatural tropes with slice-of-life humor, a formula that’s worked for hits like The Disastrous Life of Saiki K. and Asobi Asobase. But Babanba Banban Vampire leans harder into the absurdity, with the undead protagonist’s antics driving the plot.
The manga, written and illustrated by Hiromasa Okujima, began serialization in Akita Shoten’s Bessatsu Shōnen Champion in October 2021 . While the anime adaptation’s director and studio remain unconfirmed, the source material’s tone suggests a fast-paced, gag-heavy approach—perfect for the cast’s comedic chops.
The Cast: A Who’s Who of Anime Comedy
The voice cast reads like a who’s who of Japan’s most versatile seiyū, many of whom have experience balancing humor and heart. Leading the charge is Daisuke Namikawa, whose roles in Jujutsu Kaisen (as Yuji Itadori) and Attack on Titan (as Reiner Braun) prove his range. Here, he’s likely voicing the titular vampire, though official character assignments haven’t been revealed .
Joining him are:
- Yusuke Kobayashi (Fire Force, Dr. Stone), a frequent collaborator with Namikawa, who could play the straight-man teen or a rival vampire.
- Mayuko Kazama (Kaguya-sama: Love Is War, Spy x Family), known for her deadpan delivery, which would suit a no-nonsense bathhouse employee or a love interest.
- Taku Yashiro (Horimiya, Chainsaw Man), whose boyish charm might land him the role of the high schooler.
- Akira Sekine (The Rising of the Shield Hero, Oshi no Ko), a rising star with a knack for both comedy and drama.
- Katsuyuki Konishi (Gintama, My Hero Academia), a veteran whose deep voice could anchor the series as a mentor figure or another supernatural entity .
The ensemble suggests a show built for rapid-fire banter, with each actor bringing a distinct comedic style. Rumors (unconfirmed) hint at recurring Gintama collaborators being involved, given Konishi’s presence, but no official ties have been announced.
Production Mysteries: What’s Still Unknown
Despite the hype, Babanba Banban Vampire’s production remains shrouded in secrecy. Key unanswered questions include:
- Who’s directing? The anime’s creative team hasn’t been named, leaving fans to speculate whether it’ll be helmed by a comedy specialist (like Nichijou’s Tatsuya Ishihara) or a newcomer.
- Which studio is animating it? The manga’s art style is clean and expressive, but no studio has been attached yet .
- Episode count and release window: The 2025 date is vague, with no word on whether it’s a seasonal series or a shorter run. TV Asahi’s IMAnimation block is listed as the broadcaster, but no premiere month has been locked in .
- Manga-to-anime adaptation: The manga’s serialization is ongoing, so the anime could either adapt existing arcs or take a Dragon Ball Super-style approach with original storylines.
Why This Could Be a Sleeper Hit
The combination of a proven manga, a stacked cast, and a premise ripe for memes positions Babanba Banban Vampire as a potential breakout. The vampire trope is well-worn, but the bathhouse setting and workplace comedy angle offer fresh territory. If the anime nails the tone—balancing supernatural absurdity with relatable teen drama—it could carve out a niche alongside The Morose Mononokean or Interviews with Monster Girls.
For now, fans will have to wait. With so little official info, the biggest mystery isn’t the vampire’s age or the teen’s love life—it’s whether the anime can live up to its own ridiculous premise.
