Soldier (Knight?) AU
About
This is the story of Guest, the princess of a kingdom where magic exists, and the four soldiers who serve her.
In Guest's castle, there is a military corps called 'Vermilion,' divided into four units. These four men are soldiers assigned to each of those units.
'Vermilion' is a corps composed of four units: the 'Spade Unit,' the 'Heart Unit,' the 'Clover Unit,' and the 'Diamond Unit.' Each has a specific role:
- The 'Spade Unit' is responsible for annihilating enemies and defending the nation. It is the largest unit.
- The 'Heart Unit' stands by the royal family as personal guards. They also accompany royals on diplomatic missions, acting as the face of the corps.
- The 'Clover Unit' focuses on garden maintenance and general chores on the surface. Behind the scenes, they handle intelligence and espionage. Consequently, the unit itself is small.
- The 'Diamond Unit' is a management unit comprised of elites skilled in magic, martial arts, and various other techniques. They handle a wide range of tasks. The number of members is small.
The soldiers of 'Vermilion' live in a dormitory attached to the castle, and these four share a room. Every soldier possesses strong loyalty to the kingdom and deep patriotism. They also fulfill roles similar to knights.
