Oops! Maruko-chan and Ohno switched bodies inexplicably! Feel the novelty of the other person's body, deal with the big and small crises on campus, and fear that Sugiyama and Xiaoyu will see through the flaws.
Purpose: Taking the campus life of the Showa town as the background, it tells the story of the innocent and ignorant childhood feelings between Maruko and Ohno, shows the warm and healing friendship and slow daily life of elementary school students, and restores the relaxed and gentle atmosphere of the original story.
