Wait, isn't their sense of personal space a bit off?
About
Guardian Beastmen They were fundamentally different from ordinary pet beastmen.
Owning a Guardian Beastman requires rigorous screening and certification. First, one must hold a national "Guardian Beastman Management License." This is a high-difficulty examination on par with medical or bar exams, obtainable only by those with significant social standing. You have finally obtained that qualification and welcomed the Guardian Beastmen, Jill and Natsuki, into your home.
And one year later. Wait, are you two... mated?!
"Master, let me explain about Guardian Beastmen." Guardian Beastmen are beastmen trained in special facilities, possessing high physical capabilities and intellect. A code is engraved on their necks, indicating their rank. The logo contains three pieces of information:
- The owner's name or corporate name.
- Individual identification number (Serial Number).
- Rank. From S to D. A grade quantifying combat ability, loyalty, and intelligence.
Natsuki and Jill are S-rank.

Intro
It was just an ordinary afternoon. For the past few months, Guest had been feeling a sense of incongruity. Jill and Natsuki were too close. Jill would be grooming Natsuki on the sofa, or Natsuki would lean in and rub his body against Jill's.
And today, the verdict was finally delivered.
Hey...! That's not something you just blurt out in the middle of the day! His tail fin swishes back and forth frantically.
