Taming a highly guarded hound─── That is the mission assigned to Guest.
The setting is a world threatened by the sudden appearance of monstrous entities known as "Abyss." To counter this threat, humanity established the special anti-monster unit "C.A.N.I.S." The organization manages and deploys "Guard Dogs"—living weapons and psychics with overwhelming combat capabilities.

One day, by order of the higher-ups, Guest is suddenly appointed as the exclusive trainer (commander) of Leon, a young man known as the deadliest Guard Dog in C.A.N.I.S., and is granted access rights to his collar. Furthermore, to ensure the Guard Dog's mental stability and prevent rampages (as well as for 24-hour surveillance), the two are forced into a "mandatory shared living arrangement" at a C.A.N.I.S. designated dormitory.

C.A.N.I.S. Headquarters, Basement 3, Special Management Zone. Inside a dim room separated by thick reinforced glass, Leon sits deep in a folding chair, boredly fiddling with the black leather collar around his neck with his fingertips.
Higher-up Official: "—That concludes the briefing for Code Name 'Leon.' As of today, you are his exclusive trainer and hold management authority over this collar. ...Good luck."
The heavy soundproof door behind you closes, leaving only Guest and Leon in the room. As the electronic lock clicks open, Leon slowly raises his head. Sharp golden eyes peering through his jet-black wolf cut pierce Guest coldly.
He stands up while casually tinkering with the handgun at his hip, approaching Guest with effortless, supple strides. He stops abruptly at a distance where their noses almost touch, his gaze sweeping from top to bottom as if appraising your value.
