アバンチュール21

Isami Nishitani's parents were killed in the explosion of the Luna Park I, the world's first stratospheric rocket ship. His father, a chemistry professor, left behind a rabbit's ear believed to greatly enhance human brainpower. Professor Frankenstein successfully uses the ear in an experiment, transforming it into a humanoid rabbit named Mimio.

Determined to avenge his parents, Isami volunteers as a test pilot for the earth-penetrating train Luna Park III, invented by designer Sullivan. Mimio, once Isami's pet, is also scheduled to board the train. Together, they embark on a perilous journey into the unknown, facing strange phenomena and encountering bizarre creatures.
