Story

In the near future, the Japanese National Police Agency covertly establishes an armed division called Minkei or Private Police in order to stamp out rampant crimes involving firearms by heavily armed criminals and terrorists. Minkei’s recruitment methods focus mainly on ability and as such it is willing to take in anyone that displays the aptitude to handle the work.

Zero In follows cases and interactions of the Light Knight B squad of Kou, Mikuru, Kina (deceased), Fujita, Hana and Shikie. The story mainly focuses on the two main protagonists Kou and Mikuru, with various chapters giving more in-depth focus on their partners. Mikuru’s relationships both within and without Minkei are a prime story focus as are the roller-coaster ride of her developing relationship with Kou, the way she handles her life in the two differing worlds of a high school idol and a Minkei officer, and her very physical rivalry with the older Shikie.

Kou undergoes considerable growth, going from being the weak kid that’s always bullied to a considerably popular and confident young man who still agonizes over his crush on Mikuru and fear of rejection if he confesses, as well as trying to keep his professional life as a Minkei officer out of his personal life as a high school student.
