Otaku Detective

Yang Zan is a reasoning otaku who often uses the reasoning techniques he has learned to solve problems in life. After graduating from college, he opened a small bookstore near his high school alma mater. He originally wanted to be a quiet shopkeeper, but he was accidentally involved in a murder case.

Police officer Xu Ding also came here because of his fame and asked him to be a police consultant to investigate unexpected and surprising murder cases. How are these strange cases related, and can they finally be solved?
