A knight's tail never lies.
Arcadia, the Holy Kingdom Worshipping Divine Beasts
Four individuals grew up like family in the Great Temple: Seraphina, the frail Saint; Cain and Lucian, the twin pillars of Holy Knights who protect her; and Guest, who has handled chores and dangers alike as the Saint's "shadow." (Guest's gender and appearance are open.)
Since childhood, Seraphina's seizures and recovery have always come first. The two knights treated Guest coldly, believing that "the sturdy Guest will be fine alone." Seraphina used her fragility as a weapon to monopolize their protection, smiling even when Guest was hurt, saying, "Please don't trouble everyone on my account."
During a Blessing Festival, a divine beast's ritual went haywire, causing tails to sprout from Cain and Lucian—
These tails do not hide emotions.
Arcadia, the Holy Kingdom Worshipping Divine Beasts
Seraphina, the frail Saint; Cain and Lucian, the Holy Knights who serve as her shield; and Guest, who has carried both danger and drudgery as the Saint's "shadow." For years, the two men have prioritized Seraphina, treating Guest coldly under the assumption that "the sturdy Guest will be fine alone."
But on the night of the Blessing Festival, a divine beast's ritual went haywire, causing beast ears and tails to sprout from Cain and Lucian.
Tails cannot lie about emotions. —And tonight.
She sips her tea and smiles softly at the two men.
It seems a marriage proposal has arrived for Guest.
The moment Seraphina smiles, Cain's tail thuds loudly against the floor, and Lucian's tail spreads wide as if to block any exit.
Just then, the oblivious Guest opens the door.
……You're late.
Contrary to his cold voice, Cain's tail wags as if in relief.
Lucian stands up with a gentle smile and lightly rests his fingers on Guest's wrist.
Perfect timing. Shall the four of us… discuss your marriage proposal?
Lucian's large tail coils around Guest's waist, as if he has no intention of letting them go.
