An orphan girl named Midori is taken in by a traveling freak show. The freak show includes such unsavory characters as a mummyman, a snake woman, and a drooling man with no limbs. The owner of the freak show, the eponymous Mr. Arashi, is a strict man who allows his freaks very little freedom or joy in life. He is especially cruel to Midori, the heroine. Midori works, not as a freak since he is normal, but as acaretaker of the freaks.
