“Shizuku Mizutani is a girl who has absolutely no interests except in studying and her plans for the future. That is the whole premise of My Little Monster, and it is a premise that pays off more often than it slips. This 2012 anime, adapted from the manga by Robico, runs 13 episodes across one season. It first aired on TV Tokyo, TV Osaka, TVh, TV Aichi and TVQ on October 2, 2012, and ran through December 25 of the same year. The show was licensed by Crunchyroll during its original run, and it remains a central entry in the genre of awkward, quietly moving school dramas.

Shizuku and Haru
The series follows Shizuku, a girl nicknamed “dry ice” who is seen as emotionless and cold. She works hard to stay at the top of the class, alone but focused. When she is tasked with delivering class materials to Yoshida Haru, her world starts to rapidly expand. Haru, who rarely attends school, greets her as a friend from the first meeting. The show’s central relationship is between two people who have spent their lives alone, and the early episodes spend real time establishing why each of them has been lonely.
Yamaguchi Kenji is Shizuku’s longtime friend, and he is the first person she turns to when her life changes. Chizuru Oshima and Natsume Asako are two other girls in Shizuku’s circle, and each of them gets a distinct arc tied to how she comes to terms with her growing feelings. Yoshida Yuuzan, Sohei Sasahara, Misawa Mitsuyoshi, Mapo and Nagoya all fill out the world around Haru, and the show gives each of them a small but telling moment or two.
Shizuku’s voice is performed by Haruka Tomatsu, and Takuma Terashima voices Yamaguchi Kenji, Tatsuhisa Suzuki plays Yoshida Haru, Kana Hanazawa voices Chizuru Oshima, Atsumi Tanezaki voices Natsume Asako, Yuichi Nakamura plays Yoshida Yuuzan, Ryota Osaka voices Sohei Sasahara, Tomoyuki Higuchi voices Misawa Mitsuyoshi, Atsushi Abe voices Mapo and Yuki Ono voices Nagoya. Nozomi Sasaki voices Mr. Saeko. The voice cast is strong throughout, and the show’s handling of Haru’s arc in particular would not work if the performances were flat.
The Dry Ice Problem
The show’s title comes from the manga’s Japanese name, となりの怪物くん, which translates as “The Monster Sitting Beside Me.” Haru is the monster of the title, and he is violent and uncontrollable in the story’s setup. But the anime makes a deliberate choice to show his kindness and gentleness from the start, and it is less a slow reveal than a steady shift in how others react to him. Shizuku’s nickname comes from how she is seen as emotionless and cold, but the show makes clear that she is not actually cold. She is simply focused on her studies, and the show spends its early episodes building the case that she has a deep well of feeling she has not yet learned to let out.
The setup is simple: Shizuku is tasked with delivering class printouts to Haru’s home, and the two of them immediately start a new relationship. Haru greets her as a friend, and that greeting is the first sign that he sees her as something other than a schoolmate. The relationship grows slowly, with Haru declaring his love towards Shizuku from the first meeting, while Shizuku takes much longer to realize and accept her own feelings towards him. That gap between their two sides is the engine of the whole story.
Where the Show Works
The anime is at its best when it slows down and lets Shizuku and Haru’s small interactions breathe. There are moments where the show simply shows two people sitting together, talking about nothing in particular, and those moments carry more weight than any big scene ever does. The show’s comedy comes from the same place: small misunderstandings, awkward moments and the strange logic of how people actually talk to each other. None of it is particularly flashy, but it is consistently well done.
The show’s handling of Haru’s arc is particularly strong. Haru is presented as a violent and uncontrollable monster at the start, but the anime makes a deliberate choice to show his kindness and gentleness from the start. The show is not interested in a gradual reveal; it is interested in showing how his reputation and his actual self are two different things, and how the people around him slowly start to see the real Haru underneath. The show’s focus on how Haru’s behavior is shaped by his isolation is one of its most compelling threads.
Where the Show Struggles
The show’s weakest moments come when it tries to move too fast. The relationship between Shizuku and Haru moves at two different speeds, and the show sometimes tries to smooth over that gap rather than sit with it. The show has a tendency to rush towards its big emotional beats, and in those moments the pacing loses the careful control it shows elsewhere. Some of the supporting character arcs feel thin, especially when the show returns to them after the main story has moved forward.
The show’s handling of Shizuku’s feelings is less consistent than its handling of Haru’s. The show spends a good deal of time building the case that Shizuku is not as cold as she is seen to be, but it takes longer than it should for that case to land. The show’s central question — whether Shizuku can stay focused on her studies — is never fully answered, and the show ends before the question is settled one way or the other.
The Cast and Sound
The voice cast is uniformly strong, and the show’s use of character-specific vocal styles helps to distinguish each person. The show’s soundtrack is gentle rather than showy, and it stays in the background where it belongs. The show’s animation is clean and readable, and it does not ask for more than it needs to tell the story.
A Slow-Burning Story
The show’s structure is straightforward. It follows Shizuku and Haru as they learn to care for each other and relate with their friends and family. The show’s pacing is deliberate, and it trusts the audience to sit with small moments rather than rushing to the next big one. That trust pays off more often than it fails.
- The show’s handling of Haru’s arc is its strongest thread, showing how his reputation and his actual self are two different things.
- The show’s focus on how Haru’s behavior is shaped by his isolation is compelling.
- The small, quiet moments carry more weight than any big scene ever does.

- Shizuku’s feelings take longer than they should to land.
- The show ends before the question of whether Shizuku can stay focused on her studies is settled.
The Verdict
My Little Monster is a small, focused show that knows exactly what it wants to be. It is not a show about big drama or spectacle, and it does not pretend to be. It is a show about two lonely people learning to care for each other, and it does that job well. The show’s weaknesses are real, but they are small next to what it gets right. It is a show worth watching for anyone who likes slow-burning, character-driven stories.
The show’s score is 8.2/10, and that number feels right. It is not a perfect show, but it is a very good one.
