On a very pleasant morning, Tanaka is taking a nap in the school courtyard. His classmate, Ohta, carries him to class, but Tanaka continues to sleep on his desk. Tanaka’s listlessness is nothing new to his classmates, so no one is surprised. But, the usually lazy Tanaka is willing to participate in PE. His goal is to train his body and prevent his limbs from going numb or injuring himself from being lazy all day. He teams up with Ohta to play badminton...

Tanaka will spare no effort to have a lazy day. He visits a temple before school to pray for a peaceful day, but Miyano, a girl from his class, asks him to make her his apprentice. Miyano explains she wants to be a listless mature woman, but not wanting any new friends, Tanaka declines. However, Miyano doesn’t relent and Tanaka eventually accepts if it’s only for a day. Miyano begins observing Tanaka and attempts to mimic his listlessness.

Too lazy to choose what to eat for lunch, Tanaka leaves it up to Ohta. Tanaka claims he can eat anything, but if the food requires some work, he’d rather give it to Ohta. With Ohta’s encouragement, Tanaka manages to eat by himself but needs to rest on the rooftop for eating too much. While they both relax, Ohta remembers what happened that morning. There was a letter of challenge inside Tanaka’s shoe cupboard. But, the peace-loving Tanaka has decided it didn’t happen...

Ohta arrives at school carrying Tanaka as usual. He runs in the hallway to avoid being tardy but almost runs into the Class President, Shiraishi. They avoid a collision, but Shiraishi drops the handouts needed for the Student Council Meeting. Feeling responsible, Ohta and Tanaka decide to help her remake them. After school, Shiraishi is the center of attention simply walking in the hallway. Not only is she intelligent and beautiful, but she’s also down to earth and everyone idolizes her. However, the perfect Shiraishi has a secret she can’t tell anyone...

Tanaka wants to stop by the supermarket, which is quite rare. Ohta offers to help carry the groceries, but Tanaka says he needs help remembering what to buy. Tanaka’s sister asked him to buy something last night, but he has completely forgotten. The two walk around the store, trying to figure it out. “She wouldn’t ask me to buy frozen food, because I won’t get home quick enough.” “She wouldn’t ask me to buy something heavy, because I’d refuse.” They start narrowing down the possibilities, but Tanaka still can’t remember...

Tanaka arrives to school soaking wet on a rainy day. He doesn’t like using the umbrella because it’s bothersome. He took an umbrella from home, but he never opened the umbrella since it wasn’t raining much. Even though the rain started getting heavy, he continued to walk without using the umbrella. As a result, he catches a cold. At school, Tanaka realizes he forgot his textbook, so he goes next door to ask Echizen to borrow hers. He tries asking her by writing it down since he’s unable to speak due to his sore throat...

Tanaka’s class, 1-F, is going to do a haunted house for the Cultural Festival. While everyone is having fun assigning tasks, Tanaka hides his presence to avoid doing any of them. However, the only thing remaining for him to do was play the role of the ghost, the main attraction of the haunted house. Tanaka had zero motivation at first, but soon realizes people working on other tasks are much busier. With everyone’s hard work, the haunted house turns out to look like the real thing...
