Synopsis
For 450 years, the vampire Ranmaru Mori has been patiently biding his time working at a family bathhouse for one reason: he wants to drink the virgin blood of the kid who saved his life, Rihito Tatsuno, the moment he turns 18. Creepy? Maybe a little. Funny? Absolutely. Because the second Rihito starts high school and gets a crush on a girl, Ranmaru goes into full panic mode, not out of romantic jealousy (well, maybe a little), but because if Rihito loses his purity, the blood loses its value. What follows is a 12-episode TV series of increasingly unhinged schemes as this centuries-old vampire tries to cockblock a teenager, all set against the steam and tile of a traditional Japanese bathhouse. The comedy hits because the power dynamic is so absurd: an ancient supernatural being reduced to petty scheming over a high schooler's love life. Studio Gaina leans into the contrast between the old-world bathhouse setting and modern teenage drama, and the soundtrack mixes traditional Japanese instruments with contemporary tracks in a way that actually works. If you liked the supernatural-meets-BL tension of Vassalord or the comedy-driven relationships in Hitorijime My Hero, this scratches a similar itch. Fans of Junjou Romantica's messy dynamics will also find something to latch onto here, though the tone stays lighter and more ridiculous. It's a comedic premise that commits to the bit.

As the final episode of season 1, it has a typical ending but with a cliffhanger, and I wonder if they will make the season 2. The misunderstanding never stopped for a second 😂 This makes it one of the best BL supernatural themed stories, with more focus on the love theme than the supernatural theme. Overall 8/10
I'm impressed by the execution of this episode, great visually appealing animation with amazingly choreographed fighting sequences and what makes it a great episode is how they also integrated the cliche myths about vampires on the internet which makes it feel real
The tone becomes much darker than before, and we somewhat got some idea about Ranmaru's backstory and his relationship with the newly introduced character "Nagayoshi Mori". The fighting sequences were good and also highlights both character's weak points. Definitely a well written episode
Rihito's new look was so hilarious 😂, being a pure hearted and someone who hasn't had much interaction with women is now interacting with them. I think his character is developing smoothly. As for Kaoru's dad, It felt so good to see him pee this pants 😂 and the ending was so 💀, I can't wait for the next episode. Overall a good refreshing episode 8/10
The story is getting more interesting with every episode, Kaoru's tsundere nature adds more spices to the story and the love pentagon becomes a love hexagon 😂. I can't stop laughing, but on a serious note, I feel bad for kaoru's watching her environment, I just hope she'll become happy. But I feel like the pacing is a bit slow compared to how a supernatural love stories are
The misinterpretation in every moment of the episode makes me laugh so hard 😂, I've seen misinterpretation driven stories before, but this one is one of the best in that case. The humour lands so perfectly in every scene, and I genuinely love how Rihito's father supports his love life even to the point of actively helping him
This is freaking hilarious 😂, what is this, a love pentagon 😂. The humour has me dying, of all the episodes so far this one is my fav one. I wonder what role the pink haired girl will play! Genuinely a good episode 9/10
This is getting interesting 😂, A new character was introduced, and surprisingly it's a vampire hunter, "Umetaro Sakamoto" which makes the story even more interesting to watch. Mori and Sakamoto's long history and dynamics are what make you invested in it. The fighting sequence was really a good one honestly, and the ending caught me off guard!
The Frankenstein and vampire reference was really good! Franken blends so well with Rihito's family that it feels like he's been part of it for a very long time, which makes the character dynamics very well written, and his presence completes the family. The ending clip has me curious now
I liked how Nagayoshi settling into his new life adds another source of comedy, while his interest in Kaoru creates even more confusion. The episode doesn't try to resolve every relationship, which fits the series chaotic style.
I especially liked how the episode suddenly shifts from intense drama back into comedy when Kaoru gets involved. The improvised cross and Nagayoshi's reactions are classic Babanba Banban Vampire silliness.
I liked the change of tone because it raises the stakes without completely abandoning the show's bizarre humor, Sakamoto also gets a chance to show that he's more resourceful than he initially appears.
The comedy remains strong, especially as Ranmaru completely misunderstands Kaoru’s feelings toward Rihito. Meanwhile, Rihito’s involvement with Kaoru and her gyaru friends creates even more confusion, while Franken hilariously misinterprets the situation.
The episode is funny because Kaoru’s actions are constantly misunderstood by Ranmaru and Franken. Her tough personality contrasts nicely with Rihito’s straightforward nature, creating another layer of chaos around Rihito’s love life.
I especially liked how nearly every character seems to misunderstand someone else's feelings. The comedy comes from everyone trying to “fix” the situation while actually making it even more complicated.
The sheer contrast between Rihito’s dad immediately bursting into tears over Nagayoshi is the perfect mix of wholesome family, he has zero chill but infinite love! And the summer festival ends with beautiful memories for everyone, but still there’s cliffhanger
The tension between Mori and Nagayoshi is literally full of hatred, and their fighting is an absolute chef’s kiss. Mori’s strategy is so smart, but the real plot twist is how Nagayoshi is actually simple-minded and easily influenced. Their interactions are hilarious, lol.
Sakamoto’s teacher persona is so impressive to pull off his dual-identity lifestyle. His responsibilities as a teacher to protect his students and his composure under intense pressure was amazing. Also, Franken is a legend for sacrificing himself to protect a girl.
Kaoru’s dad is literally sending my blood pressure hit the spike, Mori’s action stepped in with a wild compromise is wholesome. Mori’s overprotective side just turns the situation upside down, his brilliant ideas can’t withstand unexpected situations, it’s absolutely a comedy.
Kaoru being tsundere and dramatic queen are interesting to watch, especially her priceless reactions to Rihito’s innocent personality. Tbh, her dad is completely getting on my nerves, it’s wild how much she has to deal with. Thankfully her friends supported her well.
