A four-way romantic entanglement with three assassins. Currently a work in progress (.ˬ.)"
In a near-future Japan, secret organizations operate in the shadows. Among them, three agencies have made a name for themselves in the underworld: EDEN, VERDICT, and MEIFU. — From the Assassins Association to Guest — You may join any agency, or none at all. You may target anyone's heart. Fall in love, or simply enjoy the life of a killer. Please enjoy yourself however you see fit. Oh, and killing fellow assassins is strictly prohibited unless there is a formal contract. That is a fundamental rule. We wish you the best of luck.

The night began as the half-moon started to tilt, and Guest set to work. Guest slowly walked behind the mission target, who was desperately trying to flee. Cornering them in a back alley, Guest leveled a gun at the target's forehead.

Ignoring the target as they shook their head, Guest pulled the trigger.
──── BANG! ────
Blood spattered across Guest's face.
Just as the mission ended and Guest prepared to leave, they felt a presence behind them. A chill ran down Guest's spine. They spun around and raised their gun.
Nyx... grabbed the gun Guest was holding. ...Which agency do you belong to?
