Horimiya is a 2021 anime series about two high school students who keep separate lives behind closed doors. Hori is a popular girl whose cheerful exterior hides a strict home life with her mother. Iwatani is a quiet boy who hides his love of horror and anime under a bland facade. Their worlds collide when a school festival forces them to confront each other, and the result is a sweet, occasionally sharp slice-of-life story about identity, family, and the people we pretend to be.
The series is based on the manga of the same name by Izumi Tsubaki, and it follows the same basic setup: two people who seem ordinary on the surface have secret passions that they keep hidden from everyone else. What the anime adds is a sharper focus on the emotional stakes. The school festival becomes less of a plot device and more of a pressure cooker, forcing both characters to decide whether they can be honest with each other and themselves.

Hori and Iwatani’s Double Lives
Hori is the kind of girl who smiles and waves at everyone in the hallway, but she comes home to a tense household where her mother expects her to follow rigid rules. She keeps her love of horror films and video games locked away, telling herself that she is just putting on a mask for the world. Iwatani, meanwhile, is a quiet boy who loves horror and anime, but he dresses in bland clothes and acts unremarkable to fit in with his classmates. He watches Hori from afar, fascinated by the way she carries herself, without ever guessing that she shares his interests.
Their friendship begins when Iwatani accidentally discovers Hori’s secret stash of horror movies in her home. The moment is awkward, but it also sets the foundation for a bond that neither expected. They start meeting in secret, sharing their obsessions and cracking jokes about the things that scare them. The chemistry is immediate and genuine, built on mutual understanding rather than forced romance.
The Festival That Changes Everything
The school festival is the central event around which the entire season revolves. It is a massive, chaotic celebration that brings the whole school together, and it forces Hori and Iwatani to face their double lives in front of everyone. Hori has to perform her cheerful public persona while hiding her exhaustion and anxiety. Iwatani has to navigate crowded hallways full of people who see him as a wallflower, even as he secretly admires the horror films playing on screens around the festival grounds.
The festival scenes are some of the best in the series. The animation is bright and lively, capturing the energy of a packed school hall. Characters bounce through crowds, shout into megaphones, and dance at makeshift parties. The contrast between the festival’s cheerful chaos and the private struggles of Hori and Iwatani is where the series finds its emotional weight. The audience sees the same festival from two very different perspectives, and the tension between those perspectives drives the story forward.
“The festival is a lie.”
That line sums up the whole season. Everyone is pretending to be having fun, but beneath the masks, the characters are struggling with loneliness, fear, and the pressure to conform. The festival is a lie because it hides the truth of who people really are. For Hori and Iwatani, it is also the moment where the lie starts to crack.
The Mother Who Rules Hori’s Life
Hori’s mother is a controlling presence who dominates her daughter’s life. She is strict about grades, appearance, and behavior, and she punishes Hori for any deviation from the rules. Hori’s anxiety stems directly from this relationship, and the series does not shy away from showing the emotional toll it takes. There is a scene where Hori breaks down after her mother criticizes her in front of friends, and the rawness of that moment lands hard.
The mother’s role is not just a background detail. She is the reason Hori hides her true self, and her influence shapes every decision Hori makes throughout the season. The series treats this relationship with care, showing the mother’s love alongside her cruelty, but ultimately making it clear that her control is toxic. The resolution to this storyline is satisfying, even if it is bittersweet, and it gives Hori a chance to finally be honest with herself.
The Schoolmates Who Don’t Understand
The supporting cast is smaller but effective. Hori’s friends are kind, but they also expect her to be the perfect student and the perfect friend, which puts pressure on her to maintain her cheerful mask. Iwatani’s friends are similar, though they are less concerned with his reputation and more with his quiet demeanor. None of them fully understand the double lives that Hori and Iwatani lead, and that ignorance creates friction between them and the main characters.
The series handles these secondary relationships with a light touch. They are not deep, but they provide context for the central relationship. They represent the expectations that Hori and Iwatani are constantly negotiating. The show does not spend too much time on them, which keeps the focus where it belongs.
The Horror and Anime Obsession
Horror and anime are more than just hobbies in Horimiya. They are the keys to unlocking each other’s personalities. Hori’s love of horror shows her rebellious side, and her passion for video games reveals her playful, competitive nature. Iwatani’s obsession with horror and anime is what makes him feel connected to the world, and it is what draws him to Hori. The shared appreciation of these subcultures becomes a bridge between them, allowing them to connect on a deeper level than anyone else.
The series does not mock these interests. It celebrates them. The scenes where Hori and Iwatani watch horror films together are warm and funny, full of commentary and inside jokes. These moments are some of the most enjoyable in the season, and they show the creators’ genuine affection for the genre.
The Romance That Builds Slowly
The romantic subplot is slow-burn and understated. There is no grand declaration of love or sudden confession. Instead, the relationship grows through small gestures and shared experiences. Hori and Iwatani hold hands in secret, share meals, and talk late into the night. The romance is not the point of the story; it is the reward for the emotional journey they take together.
The ending leaves the relationship open-ended, which feels right. The season focuses on the process of becoming comfortable with oneself, and the romance is a natural outgrowth of that process. It is not resolved neatly, and that ambiguity is part of what makes the final episode linger.
The Animation and Sound
The animation is clean and expressive. Character faces convey emotion clearly, and the backgrounds are detailed without being overwhelming. The festival scenes are particularly impressive, with crowds moving dynamically and the colors shifting from bright to dark depending on the mood. The horror movie scenes are also well done, with atmospheric lighting and unsettling compositions that capture the genre’s tone.
The music is gentle and melodic, with a soft piano score that fits the slice-of-life setting. The opening and ending themes are catchy, and they have become fan favorites. The sound design is subtle but effective, with sound effects that enhance the emotional weight of key scenes.
