”Jingai Kyoushitsu no Ningengirai Kyoushi,” as the title suggests, is a unique school drama that directly depicts the interaction between two types of beings who, at first glance, should never cross paths: a ”teacher who hates humans” and ”non-human girls who want to become human.” The author is Kurusu Natsume. While it is noteworthy as the debut work of someone also known as a Virtual YouTuber, the charm of this piece lies not just in its buzzworthiness, but in its delicate and warm portrayal of humanity.

The protagonist, Hitoma Rei, is a former teacher who was once called a ”teacher who cares for his students.” However, due to a certain incident, he suffered deep trauma in human relationships, closed off his heart, and lived as a shut-in. His words, ”—I hate humans,” are not mere irony but a cry from a wounded heart. In a half-desperate move, he applies for a job and is led to Shiranui Private High School, surrounded by nature deep in the mountains. He intended to lead a quiet teacher's life as a form of rehabilitation, but what awaited him was a scene far beyond his imagination.

That school is a special girls' school where non-human girls attend to ”become human.” In the classroom, beings like merfolk, werewolves, rabbit beastfolk, and bird girls sit as if it were perfectly normal, looking like residents of a fantasy world. However, this work is neither an isekai reincarnation story nor a battle series. The stage is strictly a ”school.” The theme is ”humanity.”

Why do they want to become human? Why do they admire the ”humans” that Rei detests? The reason is not mere curiosity or superficial charm. They are drawn to human weakness, imperfection, and the richness of emotions. The conflicts, clashes, and reconciliations that arise precisely because humans are neither perfect nor omnipotent. The sight of these girls finding the essence of humanity there ironically begins to sway the ”human-hating” Rei bit by bit.

Interaction with them is neither treatment nor a sermon for Rei. It is simply spending each day together. Giving lessons, giving advice, and sometimes clashing. This accumulation quietly melts his frozen heart.

The core of this story lies in the question: what does it mean to ”become human”? Is it bringing one's physical form closer to that of a human? Or is it making one's heart like a human's? What is ”humanity” in the first place? This work does not force an answer but gently leaves it to the reader.

Rei once despaired over human relationships. Yet, the non-human girls find hope in that very human society. This contrast is truly skillful. Rei, a human, hates humans, while the non-humans admire humans. This twisted dynamic gives depth to the story. And before you know it, the readers themselves are left wondering, ”What parts of humanity do I love, and what parts do I hate?”

Even without flashy magic or battles, the change of heart becomes the greatest drama. This work proves that.

While ”Jingai Kyoushitsu no Ningengirai Kyoushi” uses an eccentric setting as its entry point, what is actually depicted is a very quiet and careful story of ”rebirth.” An adult carrying trauma faces himself once again by interacting with girls who possess pure admiration. There is no excessive emotional staging; rather, the accumulation of daily life is portrayed realistically.

Those who have ever felt tired of human relationships will find this work resonating deeply. I want people who have thought ”I hate humans” to read it. And when you finish reading, you will surely feel, just a little, that ”it might not be so bad after all.”

Of course, the cuteness and individuality of the non-human girls are charming, but that is not the essence of this work. This is a story of a ”human who grew to hate humans” looking at humanity once more.
