Newly-instated detective Ishida Tomohiro returns home one day to find a naked man in his house. He asks Tomohiro to identify himself, only to vanish into thin air before the startled young man can come up with a response.
Soon afterwards, Tomohiro becomes tangled up in an odd situation involving a killer sword that can possess people. Then the same guy shows up again: this time fully clothed and actually physically present. “Kyousuke“ is a member of the supernatural task force affiliated with the police, and Tomohiro ends up being transferred there. Now he’ll have to handle all sorts of bizarre and out-of-this-world situations alongside his extremely quirky new colleagues!
Note: This is the manga adaptation of the first instalment of Kouzuki Hinowa’s two-volume light novel series, Keishichou Seikatsu Anzenbu Yuugeki Sousahan. Since the original was episodic, the events in the manga can stand alone.
