Which Chapter Features Chimera's Chimera Transformation? A Walkthrough of the Original Manga Posts
If you're looking for Chiikawa's "Chimera transformation," it appears in the short Chimera debut story collected in Volume 1, "Chiikawa no Hibi" (Chiikawa's Daily Life). We trace the original X posts, from the scene where Chimera appears already transformed, to the encounter with Chiikawa, to the highlights of the tears, wings, and striped tail.
The Chimera transformation scene is a short story in Volume 1, "Chiikawa no Hibi"
To give the conclusion first: the original chapter people search for as the "Chimera transformation" scene is the short Chimera debut story collected in Volume 1, "Chiikawa no Hibi" (Chiikawa's Daily Life). Chimera appears while Chiikawa is working on a small puzzle on the ground, and laughingly explains that it has become its current form. You can read the relevant original post via the embedded card in this article.
However, the process of transforming into a form with ears, wings, and a tail is not depicted in that post. By the time it appears, it is already in Chimera form; it states the fact of its change itself and shows its red claws and bodily movements. So the "Chimera transformation scene" in search terms is best understood, consistent with the original depiction, not as the moment of transformation but as the chapter where it reveals its changed form to Chiikawa. The statement that it "became" this way tells only the outcome—neither the trigger nor how long the change took is explained.
The standalone illustration posted on July 4, 2019 is a single image presenting the appearance head-on, while the post placed partway through Volume 6 is a single image showing only a crying face. Of these three posts, only the Volume 1 short story carries the story as far as contact between Chimera and Chiikawa, and rather than a flashy transformation, it is an introduction whose unexplained blank leaves an unsettling impression.
The sequence leading up to Chimera approaching the puzzle-solving Chiikawa
The scene does not begin with battle. Chiikawa has spread out the pieces of a small puzzle on the ground and is puzzling over where each one fits. Chimera then appears and, pressing its hands together in front of its belly, cheerfully reports the change that has happened to it. Chiikawa stops working on the puzzle and watches the movements of this suddenly appeared visitor.
Chimera spreads both arms to show the red claws on either side and begins moving as if rotating its whole body. Because its laughing behavior and sharp claws appear at the same time, its emotions cannot be read at a glance. It keeps closing the distance, and the motion of showing off its body shifts into momentum aimed at Chiikawa.
In the end, Chimera slams into Chiikawa, and Chiikawa, in pain, asks it to stop. Even so, the contact does not cease, and the two tumble to the ground together. It's a short story with a striking contrast: a quiet puzzle session shattered by an unannounced intrusion.
The Chimera's appearance across the three original posts
The July 4, 2019 post, not collected in the tankobon volumes, is an introductory illustration depicting a single Chimera head-on. One image packs in the round head connected seamlessly to the body, ears with black tips, whiskers extending to both sides, the white oval on its belly, small wings, and a long horizontally striped tail. Long tears stream from both eyes, and its mouth is open wide enough to show its tongue, but neither the reason for crying nor any counterpart is depicted. Only the name is placed vertically at the top, and with no panel layout or continuous action, it is less a chapter where something happens than a standing illustration presenting the body's features all at once.
In the Volume 1 post, that appearance turns into motion. In front of Chiikawa it presses its hands together, spreads its red claws, closes the distance while spinning, and finally slams its whole body in. Not only does it speak the words telling that it has become its current form, but the claws and the contact are also depicted, making this the central post for confirming the transformation as an actual scene.
The post partway through Volume 6, "Shisa no," is a quiet crying face with only the Chimera placed against a white background. Its pink body, black ears and whiskers, and purple-and-white striped tail are visible, with no speech bubbles or lettering. The three images serve different roles—introduction, action, and crying face—and the more you line them up, the more the scarcity of explanation stands out.
The tears, red claws, and spinning movement are the highlights
What repeatedly catches the eye in Chimera's appearance is the tears. In the 2019 full-body illustration they stream long from both eyes, and in the Volume 6 standalone illustration they flow straight down as well. Meanwhile, in the Volume 1 short story, it laughingly announces its form, presses its hands together, and moves about with claws spread. The relationship between the crying face and the cheerful behavior placed in separate posts is never explained, so appearance alone cannot tell whether it is joy or suffering.
The small wings and the long, thin striped tail also add an alien outline to the round body. In the 2019 image the whole body faces forward, letting you take in the black ear tips, the white belly oval, the wings on both sides, and the tail extending to the right all at once. The Volume 6 image, by contrast, shows the front legs tucked against its sides with the tail peeking out from the lower right, drawing the eye more to the tears than to any movement.
What lingers most from Volume 1 is the red claws spread to either side and the spinning, twirling motion. The round body, which could look endearing as a mere standing illustration, turns abruptly from cuteness into something precarious as it approaches Chiikawa and finally topples onto the ground. Across the three posts, the imbalance of the crying face set against the rough physical contact defines the impression Chimera leaves behind.
After the scene, it ends with them fallen and the puzzle left behind
After Chimera slams in with full force, Chiikawa and Chimera tumble to the ground. The puzzle Chiikawa had been working on is never completed and is simply left there. No explanation intervenes—why Chimera changed form, why it sheds tears, or where it goes after the contact—and the short story closes with an everyday activity interrupted.
The crying-face post placed in Volume 6 is likewise a standalone illustration with no conversation or preceding incident. With no speech bubbles or continuous action, only the tearful figure remains against a white background. Nothing connects it as a depiction following the fallen figures in Volume 1, so it cannot serve as material linking it to an aftermath. Rather than an explanation bridging cause and effect, the transformed figure itself is pushed to the forefront.
The curtain falls in striking fashion: no resolution or revelation, just the puzzle left abandoned. Precisely because it never explains the cause of the transformation, what remains is the sense of something alien having slipped into Chiikawa's peaceful time.
Fan theories: the "anime episode 16" memory and readings of the Chimera transformation
In multiple viewer posts among Japanese fans on X, Chimera's appearance and attack are recalled as anime episode 16. A shared interpretation is that after the food and gentle daily life of episodes up through 15, Chimera appears without warning and the atmosphere shifts. However, this holds only insofar as viewers' recollections coincide—it is not information checked against an official episode list. On the original manga side, the one thing that can be firmly connected is the short story in Volume 1, "Chiikawa no Hibi."
Some fans focus on how the fight unfolded. Some posts cite the staging of the long claws coming out and the sound as key points of the fear, and read it as Chiikawa slipping into close range where the claws can hardly reach and counterattacking repeatedly while unarmed. It is a reading that finds not just the contrast with the lighthearted introduction, but also Chiikawa's reflexive strength when cornered.
As for the cause of the transformation, one fan theory holds that a "thirst for power" may be the trigger. There are also views that see the early pink Chimera as a mid-mutation form on the way to becoming a larger monster, and posts reading it not as a modified being but as a hint of a worldview in which beings close to Chiikawa and friends rarely undergo such changes. None of these are official settings from the author; they are hypotheses born from the blanks the original left behind. It is the kind of unanswered margin that feeds the world's sense of dread.
