Furuhonya
Stopping at a used-book stall, Hachiware notices a box of certification books and recalls reading manga with Chiikawa. Hachiware calls to the shopkeeper, searches through the box, finds one book, and asks to buy it.
Hachiware finds an intriguing book in front of Furuhonya and decides to buy it after hesitating. On the way home, Hachiware looks happy holding a cookbook.

Momonga buys a book at Furuhonya's shop, is puzzled by all the text, and asks to be read to. Rōdō no Yoroi-san watches over the fun.
Momonga shows off one cute move and pose after another to get Furuhonya's attention, and finally begs to be praised while Rōdō no Yoroi-san looks on.
Momonga dives energetically into a cold bath and is shocked by the cold, then finally warms up soaking in warm water with the secondhand bookstore owner.
After seeing small round gray creatures crying loudly, Momonga imitates their crying to try to get food.
The secondhand bookstore owner calls out to the continuously sleeping Momonga to wake Momonga up, and they exchange words over directions to a place where sweets spring up.
On the sandy beach, Momonga teases the secondhand bookstore owner while tasting what is sitting on its head, and in the end the two eat together happily.
After getting a book at a used bookstore and enjoying reading it, Momonga, with mushrooms growing on the head, complains of sluggishness and sleepiness.
Momonga loves the mushroom fried rice made by the secondhand bookstore owner so much that Momonga asks for seconds and ends up eating the owner's share too.
The secondhand bookstore owner lines up used books to sell outdoors and takes a break to eat bread for lunch.
With extra head decorations to spare, Momonga gives the leftovers to the secondhand bookstore owner and warms up to them, then begs Rōdō no Yoroi-san for food.
Curious about how the secondhand bookstore owner's body works, Momonga gets excited, and the two try out movements together and laugh, with the owner finally showing a happy face.
The secondhand bookstore owner meets Chiikawa and Hachiware wearing crab hoods and happily takes a photo with them, while Momonga tries to draw attention to Momonga.
Momonga and the secondhand bookstore owner stand side by side and smile in front of a light blue background.
Handed a bag as a subjugation reward, Momonga hesitates but accepts it after encouragement from the used bookstore owner and Rōdō no Yoroi-san.
Kurimanju climbs a mountain, spots a resting Momonga and a used bookstore, then enjoys snacks at the summit.
Pochette no Yoroi-san, Rōdō no Yoroi-san, and the others excitedly discuss the travel boom, while Momonga and Furuhonya happily hold a flyer.
Momonga and Usagi join Chiikawa and Hachiware, who are surprised by a gray crowd heading to the island, as a swan-shaped boat arrives.
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.
In front of a pink background, the used bookstore owner faces forward with both hands raised slightly.
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.
After reading a book, Chiikawa and Hachiware find only a sword lying outside and realize their teacher is gone, and are shocked together with Furuhonya.
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.
Worried about their missing friend, Chiikawa, Hachiware, and Usagi join Furuhonya to discuss a plan and guidance for searching a dangerous place.
Chiikawa, Hachiware, and the others search inside a cave, reunite with Usagi and the Furuhonya group to thank them for guiding the way, and try to head to another place.
After spotting a downcast brown pair on the beach, Chiikawa and the others talk through the events surrounding the mermaid and rumors about lives.
