Soichiro should have been an inconspicuous, ordinary junior high school student. One day he saved a calico cat being attacked by ravens, which consequently made him suspected of attempted murder.
A science teacher Fuwa was convinced that Soichiro was the criminal and persistently examined him. Finally, the boy was forced to confess his family's secret. “Actually, I'm a ninjya.” This is a fantastic mystery featuring the shinobi (ninjya) boy, the stubborn teacher, and an enigmatic high school girl.
