In comes Takashi Shirogane, a soldier hired from overseas to guard the Galra generals that lord over London. He did not come all the way across Asia to be kidnapped by a grouchy assassin, but here he is.

Runaway - kingseijuro @kingseijuro

5k. (Mature). Contains: graphic violence.

Assassin Shiro

Scarlet Moonflowers - Holyangelheart

2k. (Teen).

"As the night progressed, Shiro found it harder to eliminate his target. By now he was supposed to have stuck a needle into the back of his neck or even suffocate him with the chloroform he keeps on him at all times. Even using a classic chokehold or his silent pistol to shoot a bullet in between his eyes was the last resort he rarely used."

Assassin Sheith

Traitor - Child_OTKW

4k. (Not rated).

 Keith rolled his eyes, even though the words drove a stake through him. "Oh please, switch agencies one time and suddenly you're the bad guy."

Shiro lifted him by his shirt, only to slam him back against the floor. "'Switch agencies'? 'Switch agencies'? You left us." He hissed, getting close to Keith's face. "You up and joined the enemy without a single explanation. You willingly traded away our secrets. You betrayed all of us. You betrayed me."

It's been a year since Keith betrayed Voltron and joined Galra Industries. A run in with Shiro brings back some painful feelings, but is Keith really the traitor they think he is?

Shirogane Takashi is dead.

Keith, an assassin working within the dangerous yakuza underworld, knows this better than anyone because he killed him himself.
