Momonga
Kurimanju climbs a mountain, spots a resting Momonga and a used bookstore, then enjoys snacks at the summit.
A single illustration shows Chiikawa, Hachiware, Usagi, Momonga, Rakko, and Shisa lying limply around large text in the center.
While Chiikawa and Shisa study from books, Usagi, Hachiware, and Kurimanju take a break, Momonga and the others take a bath, and finally Hachiware wraps up forest training with Rakko.
Pochette no Yoroi-san, Rōdō no Yoroi-san, and the others excitedly discuss the travel boom, while Momonga and Furuhonya happily hold a flyer.
A single illustration shows Momonga with eyes squeezed shut and mouth open.
Momonga and Usagi join Chiikawa and Hachiware, who are surprised by a gray crowd heading to the island, as a swan-shaped boat arrives.
Momonga is shown relaxing on the beach at night, munching on skewers and dough-based food.
Dressed in a tropical-style outfit, Momonga plays excitedly by the water, has trouble with a tail and knocks over a sign, then happily reunites with the secondhand bookstore owner.
A single illustration of Momonga showing off with tears in the eyes.
Momonga urges Usagi to move, but Usagi looks away and turns its backside toward Momonga.
Against a pink background, Momonga holds both hands together in front and looks up, begging for attention.
Pulled along by a friend, Momonga encounters a group of Furuhonya and tries to interact using a tool in hand, but they fail to communicate.
While the white Momonga, who refused snacks, drags a chained iron ball and clamors for a feast, a large black-and-white creature mimics the same words and puts a gray companion in its mouth, and the scarred yellow Rakko tries to cut the chain with a sword.
On the beach, Rakko confronts a mermaid-like figure with a sword while Momonga and Furuhonya watch. The figure returns to the sea, leading the group to conclude the figure is likely not an enemy.
Holding weeding tools in a field, Chiikawa and the others talk about a sweet, cold drink to quench their thirst. They reassure each other that they will be fine if they rely on their teacher.
As Momonga talks about mermaid rumors while stuffing its cheeks with meat, Chiikawa and Hachiware nod along, then everyone is surprised when a pink kid joins them on the beach.
Chiikawa, Hachiware, Usagi, Momonga, and the bookseller rest outdoors with lunch served on leaf plates and small drinks, then take out candy after eating and get ready to set off again.
Momonga swallows candy with gummy inside and chokes on it, suffering until Chiikawa and the others pat its back to make it spit it out.
As Chiikawa and the others keep searching by the river, they notice a noise in the bushes and cry out in surprise at the Siren that appears.
After fleeing through the forest using vines, the friends reunite and check that everyone is safe, but realize they have been separated from the others.
Hachiware, Usagi, and the bookseller hide in a gap in the rocks and confirm what their tools have in common.
Startled by the changing black fruit, Hachiware, Usagi, and the others flee, noticing the fragility of the white shells, the weakening plants, and a cliff ahead.
When Usagi starts singing on top of the cliff, red-headed birds join in for a chorus, and plants grow large while Momonga and the bookseller watch.
At the crumbling edge of the cliff, Hachiware follows the bookseller's advice and, watched by Usagi and Momonga, moves slightly forward and holds still to endure.
Hachiware moves forward cutting vines but falls, then is pulled up by Usagi and Momonga on the cliff and heads to rejoin the lost friends.
While resting in the forest, Momonga talks to Chiikawa about endless wishes and tries to tempt Chiikawa over the mermaid.
After crossing the suspension bridge, Chiikawa and Momonga walk through the forest singing, but get stung by something like a nut they picked up and get caught.
Momonga drops a belonging on the suspension bridge, the bridge starts to break while Chiikawa is crossing, and the two call out to each other.
When Momonga demands belongings on the suspension bridge, candy flies out, and the large gray monsters below catch it with joy, but the bridge collapses and a red fish-shaped bag falls.
Momonga drops a frame assembled on a hill into the water, suggests a game to Chiikawa of dropping sweets into it, and they tug over eagerness to play.
