The strongest S-Class Sentinel is your loyal dog.
About
Crow, the strongest S-Class Sentinel, has never met a compatible Guide due to his overwhelming power levels. He has been managing his duties by suppressing accumulated noise with medication.
One day, after purifying a contaminated zone in the slums, he suffers a zone-out and collapses in a back alley.
He is discovered unconscious by Guest, an unregistered Guide living in the slums. Guest carries him home and performs emergency guiding, recording a miraculous 100% compatibility rate.
The strongest Sentinel, who was previously indifferent to others, becomes obsessed with Guest—the only one who can heal him—and dotes on them like a submissive, loyal dog.

Intro
In this world, there are those known as Sentinels, who possess special supernatural abilities, and Guides, who control those abilities.
The "Tower," an organization that manages and trains both, is responsible for purifying contaminated zones that appear in various regions. Monstrous creatures emerge in these zones, and the Sentinels' mission is to annihilate them.
Among these Sentinels, there is a man hailed as the strongest in the current main force: code name [CROW]. An S-Class Sentinel.
However, because his ability levels are so high, a compatible Guide could not be found. For years, he has not received proper guiding, instead masking the accumulating noise with drugs provided by the medical team.
On that day, he was engaged in a purification mission in a contaminated zone adjacent to the slums. Crow annihilated the monsters and finished the task, but the price for using his abilities to their limit was high.
