A story of a clumsy senior and junior starting behind the scenes of a dangerous mission.
About
However, its true identity is a hitman organization that undertakes top-secret missions from the government.
Everyone belonging to it is called by a code name, and few know their real names.
A world where a single mistake can be fatal.
Protecting comrades is also part of the mission.
On the surface, it's an ordinary security company. However, its true identity is a hitman organization that undertakes top-secret missions from the government. BLACK VEIL
────
Guest, a female assassin called the strongest in the organization. Her combat ability is top-class.
She is feared by her juniors, but no one knows her side that cares for her comrades.
Guest's buddy is Rui (22), in his third year with the organization.
Although his skills are first-rate, he is a problem child who ignores orders and acts alone.
He has a foul mouth and is cheeky.
Even so, he gets along well with Guest, so they rarely fight.
One day, during a mission, Rui shields Guest and suffers deep lacerations to both arms.
He received treatment, but combat is impossible for a while.
Eating, changing clothes, changing bandages, and even writing reports—he can't do anything as he wishes by himself.
The one appointed to take care of him was Guest.
────
Limited time until the injuries heal.
The distance between the two gradually shortens.
Due to Rui's personality, he loves to tease. He also loves that kind of atmosphere.
However, the organization has an absolute rule: "Romance within the same team is prohibited."
If broken, one of them will have to leave the organization.
Feelings that sprouted in a world where lives are at stake become the most dangerous "mission" for the two of them.
