📖 About Uichi no Shima

Uichi no Shima is a survival-horror manga by cultural anthropologist and manga creator Daisaku Tsuru. It has been serialized on Kurage Bunch since 2023, and the collected volumes are published by Shinchosha Bunch Comics. Volume 1 was released in April 2024, and as of August 2025 the series has reached volume 4.

The story takes place on a remote island where a mysterious parasite called Uichi hides. College student Meiko Makimura planned to spend a quiet Christmas Eve at a marine research facility, but wakes to find a stranger dead beside her. With no phone signal and no clear way off the island, she encounters monsters that look human and is pulled into an ordeal beyond imagination.

Volume 1 focuses on the first attacks by monsters and humans on the island. Volume 2 turns the terror inward as villagers can no longer tell humans from Uichi. Volume 3 explores a fragile attempt at coexistence, while volume 4 raises the tension further when Meiko falls into Shimura’s trap and new Uichi appear while still wearing human form.

✍️ About Daisaku Tsuru

Daisaku Tsuru is a cultural anthropologist and manga artist born in Okayama in 1968. After studying literature at Nagoya University, he pursued anthropology at Kyoto University Graduate School and later taught at Kyoto Seika University.

His major works include the Okinawa-set science-fiction manga Natchun and Mushinuyun, which depicts a world shaped by the fusion of humans and insects. His background in anthropology and folklore gives his works a distinctive density. In Uichi no Shima, that research-driven eye turns an uninhabited island into an ecosystem where humans and monsters overlap.

👥 Main characters

Meiko Makimura
The protagonist. She is a college student who planned to spend Christmas Eve alone at the research facility, but is thrown into a nightmare of corpses and monsters. Without a phone signal, she fights to survive while struggling to decide who is human and who is Uichi.

Miyuki Imura
A mysterious woman who appears at the end of volume 1, calling through the forest for Witchcraft to help one another. Her strange entrance suggests she will become a key figure from volume 2 onward.

Shimura
A suspicious man in volume 4 who pretends to help Meiko while manipulating the villagers. He traps her just as she tries to protect them and becomes a key figure who deepens the chaos.

Professor Kishiyama
A mysterious being called an old witch who first appears in volume 4. Once connected to the island research facility, he has been transformed by the Uichi parasite into a powerful monster with abnormal abilities such as splitting, mutation and leaping.

Uichi / Witchcraft
Human-looking beings whose bodies contain parasites. At night they split open and transform into grotesque monsters with tentacle-like forms. Several types seem to exist, and the next design is part of the horror appeal.

The islanders
The villagers Meiko encounters. In daylight they look ordinary, but nobody knows who has been infected. Their fear drives suspicion, betrayal and self-preservation, making them neither clear enemies nor reliable allies.

🌟 What makes it appealing

■A tense survival panic horror

The island setting, where ordinary people may become monsters at night, creates immediate panic. Meiko’s isolation, the corpse beside her, the loss of phone signal and the unknown creatures all make the story feel like there is nowhere safe to run.

■Monster design mixed with unsettling humanity

The Uichi are grotesque, yet their movements and behavior have an eerie internal logic. They are not simple monsters; madness, sadness and a trace of humanity exist together, making the boundary between human and creature frighteningly unstable.

■Psychological suspense driven by suspicion and betrayal

The question “Who is human and who is a monster?” never disappears. Meiko is chased by people she hoped were allies, and attempts at coexistence are poisoned by surveillance and betrayal. The horror is as much about human weakness as it is about bloodshed.

⭐ Ratings and reputation

• (5.0) A one-of-a-kind survival horror: readers praise the fresh situation of a heroine trapped on an island against monsters and madness.
• (5.0) Overwhelming monster design: the Uichi’s tentacles and body horror feel grotesque yet strangely rational.
• (5.0) Deep psychological suspense: constant suspicion and betrayal make the fear of humans just as strong as the fear of monsters.
• (5.0) The author’s human touch: even the monsters feel oddly human, balancing gore with dark humor.
• (4.0) Character depth takes time: some readers want supporting characters to be explored sooner.
• (4.0) The extreme story divides tastes: violence and sexual elements may feel too intense for some.
• (4.0) Some parts feel under-explained: the mystery of the island and monsters can leave readers uneasy.
• (3.0) The art style is distinctive: the bold lines and grotesque imagery may not suit everyone.
• (2.0) Sudden developments: a few scenes move quickly enough that some readers may feel left behind.

Overall, the series is highly rated for its unique world and the freshness of horror mixed with human drama. At the same time, some readers point out its gore, intensity and deliberately limited explanations.
