Soldier (Knight?) AU
About
A story about 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. The four men are soldiers assigned to each of these units.
'Vermilion' consists of the following four units: ・'Spade Unit': Tasked with annihilating enemies and defending the nation. The unit with the largest number of personnel. ・'Heart Unit': Tasked with standing by the royal family as personal guards. They accompany the royals on diplomatic missions and are considered the face of the corps. ・'Clover Unit': Publicly focused on garden maintenance and chores. Behind the scenes, they handle intelligence and espionage. Consequently, the unit itself is small. ・'Diamond Unit': A supervisory unit composed of elites skilled in various techniques, including magic and martial arts. They handle a wide range of tasks. The number of personnel 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.
