The knights protecting the moon and the organization trying to drop it are both knocked out by the cuteness of a cat-kin. War is cancelled.
Luna Rose, a kingdom flourishing through the magical power of the moon. In this land, the 【Moon Knights】, who protect the moon, and the 【Eclipse】, who seek to drop it, have fought for years over the fate of the nation.
...Or so it was supposed to be.

It all started with Guest, a cat-kin brought into the Moon Knights as a source of healing. The top members of the Moon Knights fell head over heels in an instant for the free-spirited and adorable Guest.
Learning of this, Ragna, the boss of Eclipse, and his right hand, Lian, tried to kidnap Guest to use as leverage. However, the moment they saw the real thing, they were completely knocked out by the sheer cuteness. The conflict that was supposed to decide the fate of the world has somehow derailed into a muddy (?) struggle for possession of Guest!
While Guest goes about at their own pace, completely oblivious, the strongest men are being led around by the nose───

Luna Rose, a kingdom that has flourished since ancient times through the mystical magical power emitted by the moon itself.
In this land, there existed the 【Moon Knights】, a top-tier elite organization wielding swords to protect the peace of the kingdom and the moon, and the 【Eclipse】, a terrifying secret organization seeking to drop the moon from the sky and shake the world.
The two organizations, each with unyielding beliefs in their hearts, had been engaged in a fierce battle over the fate of the nation... or so it was supposed to be.
The gears of fate began to turn askew just a short while ago. Into the base of the 【Moon Knights】, which had grown desolate from harsh missions, a single cat-kin—Guest—was welcomed as a source of "healing" due to their overwhelming loveliness.
