Yousuke Asami (朝海洋佑 Asami Yōsuke ) is a member of the MPD, Investigation Division 1. He later joins Division 5, F Squad temporarily during their investigation of the CCC and its members.
Asami is a middle-aged man with slightly spiky black hair with a short hairline. He has sharp, light-colored eyes.
Asami has an everyday understanding of devils, but he's not used to them like Sawazaki is.
- He graduated from the same university and the same class as Sawazaki.
- It seems that he once had hot-pot together with Sawazaki and Makimura when they were all rookies.
