Year 2022 A.D. At a time when anyone can travel around the world, there are more crimes occurring than ever. To protect the country from political terrorist attacks, a new Security System Garrison was created 8 years ago. To destroy this organization, terrorists have started aiming at the leaders of the Garrison, the Instructors.

Seven Instructors have already died in the line of duty, and to avoid another death, the 8th Instructor, Ishikawa Haruka, was given an assistant who would also act as his bodyguard. Iwase Motohisa, previously the Prime Minister's SP, falls in love at first sight with Ishikawa during a chance meeting, and then asks to be assigned as Ishikawa's assistant.

As the towns and cities grow, the people who have Ascended to immortals disguise themselves as mortals in the cities, part of them can’t help themselves but to devour humans, but other than these cases showing up in headlines and on the news, there aren’t any other effects.
