Penguin Highway

Penguins suddenly appear in the town with no explanation. Aoyama finds that the penguin species is known to follow a singular path known as the "Penguin Highway," which leads to the woods. After the bully Suzuki ties Aoyama up to a vending machine, the Lady frees Aoyama and transforms a soda can into a penguin. At school, Aoyama finds Uchida and his other classmate Hamamoto with a penguin named Penta on the rooftop. They bring Penta on the train, where it falls ill upon leaving the station. Penta stumbles out of the cage and transforms into a soda can. Aoyama then goes to a cafe to play chess with the Lady, where she mentions her trouble sleeping after reading about the Jabberwock. The power goes out, and she accidentally transforms the pieces into bats. Aoyama later deduces that the Lady can turn thrown objects into penguins in the light and bats in the dark. The next day, Hamamoto leads Aoyama and Uchida deep into the forest, where a floating sphere of water sits, which she calls the "sea". The next few days, Aoyama, Uchida and Hamamoto, spend playing around the sea and investigating it. Uchida throws in a toy spaceship into the sphere, and it sucks up the toy. One day, Suzuki comes to bully Uchida and Aoyama, happening upon the sphere, and Hamamoto warns him not to tell anyone about the sphere. The next day, the reporters note a new unidentified creature has been discovered. Aoyama and Uchida spot the creature eating a penguin. The Lady asks Aoyama to go to the coast with her, and they depart by train. As they leave the station, the Lady falls ill. Her sweat falls onto the ground, liquifying the concrete into the creature — a Jabberwock. He does not see the Lady after that for a while. After school, Hamamoto and Uchida go to find the forest blocked off. Entering despite the warnings, they find Hamamoto's father conducting research, with Suzuki revealing the sphere's location. A huge storm brews as the sphere grows in size. The next day, it is revealed that the sphere has expanded to a dangerous extent, leading to the disappearance of Hamamoto's father. The school holds a lockdown, and Aoyama escapes to meet up with the Lady. Aoyama solves the mystery. The sea is the energy source for both the penguins and the Lady, but the penguins try to destroy it. The sea displaces space and distorts time. Aoyama believes the sea is a hole, a place where the world is torn. The penguins are trying to destroy it in an attempt to repair the world. However, making too many penguins causes the Lady to fall ill. In response, she produces the creature, known as the Jabberwock. These attack the penguins, which makes the sphere larger and result in her improved health. Aoyama and the Lady walk toward the forest, generating a mob of penguins. They blast their way into the sphere and land into the apocalyptic future. Aoyama and the Lady rescue Hamamoto's father and the other researchers. The penguins fly up and pop the sphere, causing water to rush out into the real world. Aoyama and the Lady return to the cafe to talk, while the mob of penguins slowly disappear. When the last penguin disappears, she hugs Aoyama and leaves the cafe. Outside of the window, she disappears. He resolves not to cry, believing he will see her again and will tell her that he loved her. ==Characters==
