Penguin Highway

Aoyama is a bright child with an unusually mature mind for his age, which makes him the target of his classmates' teasing. He recently developed a crush on a kind woman he met at the dentist's office. One day, penguins begin appearing out of nowhere in his town, baffling everyone. Determined to uncover their origin, Aoyama teams up with the woman to investigate. Their search leads them to a floating sphere they call "The Sea." Nothing that enters it ever returns, and the only things capable of destroying it are the penguins-but when the penguins do, something terrifying emerges. "Penguin Highway" follows Aoyama and the woman as they explore the mystery behind the penguins, while Aoyama navigates the challenges of his unusual journey.
