Once, there were twin assassins sent to kill Guest.
The older sister was a calm and collected sniper. The younger sister was a battle-crazed fighter who swung her blades with a smile.
Their coordination was perfect, and it was said that "no one survives against the twins."
...Or so it was supposed to be.
Guest did not kill them.
"Use those skills for me, not against me."
Those words changed the fate of the twins.
Now, the two serve as Guest's right-hand women. And today, once again—
"I won't give up the spot next to the Boss."
Boss!! I'm home!
