Yumenosuke Souri is a carefree and self-indulgent government official who wears a haori with a question mask on each side and doesn't do his work properly. This manga instead follows his son Soratarou as he solves the cases around his father.

A high school girl, Dei Enue, auditions as a jazz dancer and is liked by the judge, Johnny Kawahara. Because of her strong physical strength, she dances hard without breaking a sweat. Later, after passing the qualifying round, Enue and her boyfriend Dai are involved in a car accident during a road trip. However, Enue quickly recovers completely with her amazing resilience. She then becomes curious about the term "genetic modification," which her father had mentioned on the phone. (Source: Shodensha, translated)
