List of Chiikawa Enemy Characters | A Guide to the Mysteries and Subjugation Targets of the Original Work
A list of Chiikawa's enemy characters and mysteries, organized by name, type, first appearance, and features. Drawing on the original work's depictions, this guide explains the dangers and appearance scenes of the Mitsuboshi restaurant owner, Chimera, Ano-ko, Dekatsuyo, Yamanba, the Siren, the parasitic mushroom, and more.
List of Chiikawa Enemy Characters and Mysteries
In the original Chiikawa, the cast includes not only attackers but also mimic-types that turn from friendly forms into danger, subjugation targets faced as a job, and mysterious entities that act on bodies and time. The main hostile beings include the Mitsuboshi restaurant owner, the Rock-Paper-Scissors Mimics, Chimera, a giant Chiikabu (the Beetle), Ano-ko, Dekatsuyo, Goblin, Yamanba, Black Star, the Siren, and the parasitic mushroom.
Even when they appear in the same list, their positions are not uniform. Ano-ko appears both as a subjugation target the characters confront and, at night, sweeping away a different group with its tail, and Chiikabu (the Beetle) also shows a dangerous form after spending time with Chiikawa in a small body. Rather than fixing good and evil by name alone, laying out each first appearance alongside the actual harm and strange changes shown reveals what makes each one frightening.
If you want to explore without diving into the heart of the story, the easiest way is to start with the Arc pages for each first appearance. In the Three-Star Restaurant Arc, a dining restaurant turns into a trap; in the Big Subjugation Arc, the three gear up and approach a giant opponent; and in the Parasitic Mushroom Arc, a strange change appears on Chiikawa's own head. The unease of this series comes from having both enemies pressing in from outside and mysteries that slip inside.

The Mitsuboshi Restaurant Owner | The Enemy Who Turns Customers into Cooking Ingredients
Before Chiikawa and Hachiware, who had been thinking of buying food with their reward, appears a large, unsettling figure with a conspicuous tongue and mouth. The two, mid-conversation about a meal, stop in their tracks and size up the figure—and it becomes clear that the reasonably priced Mitsuboshi restaurant is no ordinary establishment. With no explanation beyond their first face-to-face encounter, the scene tips abruptly from everyday life into danger.
In the back of the restaurant, a large green figure uses bathtub- and pot-like containers and begins treating the two not as customers but as ingredients. It then spreads something oil-like on Hachiware, calling it "moisturizing," sprinkles salt and pepper and calls it "a good-luck charm," and wraps Chiikawa and Hachiware in tortillas. Even something red is placed on their heads, and green legs approach the two, now arranged on a plate. The restaurant's polite euphemisms flip into a dangerous cooking procedure—it's gourmet horror you can't laugh at.
Ano-ko | The Subjugation Target Faced by the Three After Gearing Up
In the Big Subjugation Arc, Chiikawa, Hachiware, and Usagi rise into the sky on the rotor blades on their heads, then descend in the same direction carrying what appear to be subjugation tools. Because they prepare and approach from a high vantage point, the target's size and the tension of the job come across first. The sight of the three small figures lined up in midair carries the exhilaration of an adventure tale taking on a big catch.
Beside a grove of trees, the three stop in their tracks before the presence of a huge opponent. Chiikawa watches the situation anxiously, Hachiware thinks of a way to help without overextending, and Usagi uses what he's carrying to press forward. Through the large shadow and branches and the tools at their feet, the scene even shows their hesitation before stepping in toward the target.
As the distance to the even larger Ano-ko closes, the parts extending from its body and the surrounding shadows complicate the three's path. Chiikawa, overwhelmed, never looks away; Hachiware keeps track of his companions' positions; Usagi readies his tools. Because the giant outline and the three's smallness can be compared in the same frame, the encounter makes the name "Big" itself feel like pressure.
Ano-ko at Night | A Position That Can't Be Reduced to Subjugation Target
In Volume 4, "Ano-ko," small black figures approach Ano-ko on the ground at night, moving as if to surround it. Ano-ko swings its long tail to sweep away the approaching figures, then picks up what look like scraps of food scattered at its feet and carries them to its mouth. The number of black shadows and the movement of the huge tail create a tension different from the calm daytime scenes.
Who the small black figures are, or why they gathered, is never explained. In another night scene they form a line, some carrying thin objects or what look like instruments, so they are hard to grasp as a simple attack. Precisely because Ano-ko does not look like a one-sided threat, the nightscape with its blurred friend-enemy boundary feels all the more unsettling.
Parasitic Mushroom | The Mystery That Begins Inside the Body
In Volume 6, "The Parasite," something white and mushroom-like grows from Chiikawa's head. Hachiware realizes it may be a parasite, mentions having had a similar experience himself, and decides to remove it. Beside this carefulness—checking the base and reaching out while taking care not to cut the skin—there is even talk that a previously parasitized one was delicious when stir-fried and eaten. A strange mystery with an oddly everyday feel, where treatment and memories of a meal proceed side by side.
But partway through the procedure, the mushroom stretches further and lifts Chiikawa's body. Seeing what looks like the base fall off, Hachiware takes it to mean the root has come out, yet the remaining mushroom begins moving on its own. Chiikawa is swung around by the part extending from above, while Hachiware looks back and forth between the fragment in his hand and the moving mushroom. A nasty surprise of a bodily mystery: a treatment that should have ended with a cut produces a new movement instead.
Distance from Enemies, Seen Through the Actions of Chiikawa, Hachiware, and Usagi
Cornered in the Mitsuboshi restaurant, Chiikawa runs clutching green food spilled on the floor and a pink fork, bewildering the large opponent. Hachiware picks up the signal sent with a sideways glance, judges it an opening, and starts running—followed by a voice announcing they've come to help and Usagi's arrival. Chiikawa, who had only been frightened, moves the situation; Hachiware reads the intent; and Usagi leaps in from outside—their coordination in action.
In the Big Subjugation Arc, the three carry equipment from the start and approach the target from the same direction. With the parasitic mushroom, Hachiware reaches for the base, careful not to hurt Chiikawa's skin. The distance from an enemy changes depending on whether it's the closeness of creating an escape route, the closeness of closing in for a job, or the closeness of treating a friend. That strength can't be measured by physical power alone is part of the fun of comparing these three encounters.
Fan Theories: An Enemy Character's Appeal Isn't Decided by Scariness Alone
Five reactions found among Japanese fans on X aren't enough to determine a popularity ranking for the enemy characters. Among them were voices saying their favorite is Chimera, an enemy character who speaks of how it "ended up like this," and voices praising Chiikawa's quick thinking and courage in the Volume 1 scene where, while acting alone, he encounters Dekatsuyo and drives it away. The view is that what lingers is not just the enemy's design, but also the actions of the Chiikawa characters who faced them.
In reactions from people who saw the movie, some fans back the Siren for her cuteness, while others rate her as a formidable enemy for her intelligence in anticipating powers and strategies—both views confirmed among Japanese fans on X. There was also the take that those who sense danger and try to protect their friends tend to meet the harshest fates. Rather than popularity poll numbers, looking at what drew people in—the design, the fighting style, or the courage and suffering of those who encountered them—brings the contours of fan impressions of enemy characters into focus.
Reading in Publication Order: From Mitsuboshi to the Parasite
The publication-order flow is Volume 2 "Mitsuboshi," Volume 3 "The Big Subjugation," Volume 4 "Ano-ko," and Volume 6 "The Parasite." In Mitsuboshi, entering an affordable restaurant layers dining with danger; in the Big Subjugation Arc, the distance closes between the three, equipped, and the huge target. Afterward, a small black group appears around Ano-ko at night, and in the parasite story, the mystery reaches Chiikawa's own head. It's a reading order in which the unease deepens step by step, from outside threats to changes arising within the body.
To keep spoilers in check, start by opening only the post cards in the list, then move to the Arc pages for whatever catches your interest. For Mitsuboshi, the range covers the part where the two are treated as cooking ingredients; for the Big Subjugation Arc, the encounter with the huge Ano-ko; for the night scene, sweeping away the black group with its tail; and for the parasite, up to where the mushroom moves independently. Without getting ahead of the outcomes, you can compare the moment of appearance with the form the danger takes.
