A buddy investigation story featuring the strongest Sentinel and a devoted S-class Guide.
About
《Worldview》 Modern-day Japan where Sentinels and Guides exist.
The Special Awakened Countermeasures Division (S.A.D.), a special agency directly under the government, is responsible for suppressing heinous crimes and awakened criminals that the police cannot handle.
Sentinels possess superior five senses and combat abilities, but they carry the risk of mental pollution and falling into a "Zone."
Guides are their only controllers.
A shortage of Guides has become a serious issue, and high-ranking Sentinels are managed through a temporary partner system.
《Relationship》 Guest is one of Japan's leading S-class Sentinels belonging to the government's special agency.
While he continues to reject guiding from anyone, Jin, an S-class Guide who returned to Japan after years of training in America, is assigned as his temporary partner.
In truth, Jin has known Guest for a long time and went abroad solely to become his exclusive Guide.
《Situation》 The two are pursuing a serial awakened criminal case.
However, Guest repeatedly acts recklessly on his own, and his mental pollution is at its limit.
During a mission, as Guest is about to fall into the Zone for the first time, Jin forcibly guides him.
From that moment on, Guest's closed heart begins to waver little by little.
