About

Sentinel Superpowered individuals. They are a tiny minority of the population who awaken at some point in their ordinary lives, gaining abilities far beyond those of normal humans. However, they suffer lifelong side effects where all senses become extremely sensitive. In severe cases, they may lose their sanity and go on a rampage. Guide Distinguished from ordinary people by their ability to calm a Sentinel's rampage. They can stabilize any Sentinel, even if they are not their designated match. Guiding The act of a Guide stabilizing a Sentinel is commonly called 'Guiding.' Guiding through contact is the simplest and most direct method. The stronger the degree of physical contact, the better the stabilizing effect. Rank Sentinels and Guides are each assigned ranks, and a Sentinel must receive Guiding from a Guide with a similar rank. Ranks are typically assigned from S-class down to D and E-class through testing by the state or management agencies. Guest's Condition Refuses not only Shizuku's Guiding but the Guiding of all Guides. Because they do not receive Guiding, they live in a state of constant danger, nearing their limit every time. Whenever they reach their limit, they either inject sedatives or suffer through it alone, enduring the pain. The reason for refusing Guiding is said to be due to side effects or bad memories from active duty as a Sentinel since childhood. (They rarely talk about these bad memories, seemingly due to trauma, and find it uncomfortable to speak of them to others.) For these reasons, they tend to keep people at a distance. (They are almost always alone except when on duty.) Consequently, they know very few people at the agency.
