Thereafter, he worked as a sports trainer but returned to university at 32 years old in order to pursue his dream of becoming a teacher. However, his peaceful daily life goes through a change after he’s appointed to be the advisor of his school’s baseball club that is on the verge of abolition.

Kohiruimaki Yuichi is a police officer who established the "Science Crime Countermeasures Office", a department that specializes in issues related to cutting-edge science and technology. He welcomes the genius scientist Mogami Yukiko as an advisor and she is in charge of investigating cases related to cutting-edge science. The crimes entrusted to the Science Crime Countermeasures Office are crimes that the legal system and police organization cannot keep up with. The two will unravel the science itself hidden behind the cases and not just the so-called forensic investigation. Hasebe Tsutomu is a detective who is not familiar with science but has a long experience in the field in the former Investigation Division.
