Penguin Highway

Aoyama approaches the world like a young scientist, recording observations and looking for explanations. When penguins appear in his inland town, he finds a mystery worthy of his full attention.

The puzzle deepens after a woman from his dentist's office turns a discarded drink can into a penguin. Together with his school friends, Aoyama follows the strange connections through an unforgettable summer, discovering that curiosity can lead far beyond the answers he expected.
