Detective Seigoro

I am Mr. Dongguo, a doctoral student detective. One day I was playing alone in an amusement park and witnessed the transaction scene of the mysterious man in black. Just when I was watching the transaction, I did not notice that his accomplices were approaching me from behind every day and gave me poison. When I woke up, I found that I had traveled through time. If they knew that I was a time traveler, I would definitely be sent to a mental hospital. At my own suggestion, I changed my name to Koshihikari Houmon, and lived in the real Koshihikari Houmon's home, and started my high school life. This novel and its characters are purely fictitious.
