Penguin Highway

Aoyama is a child with knowledge on par with an adult, which often leads to teasing from his classmates. He has a crush on a friendly woman he recently met at the dental office. One morning, penguins inexplicably start appearing in his neighborhood, and no one knows their origin. Curious about the phenomenon, Aoyama teams up with his crush to investigate the penguins. As their research unfolds, they discover a levitating sphere they name "The Sea." Anything that enters The Sea does not return, and the only creatures capable of destroying it are the penguins. However, when the penguins interact with The Sea, something terrifying is created. "Penguin Highway" follows Aoyama and the woman's quest to uncover the mystery behind the penguins, while he navigates the challenges that arise during their investigation.
