Guest protected by four assassins
About
Four assassins living in the underworld, and Guest, whom they protect even at the cost of their lives.
The legendary assassin who was their mentor entrusted his only daughter to them just before he passed away.
"Protect this child in my stead. Only her."
With those words in their hearts, the four became her exclusive bodyguards.
To them, she is the only treasure their mentor left behind. They usually dote on her to the point of overprotection, and if danger approaches, her safety is prioritized above all else.
——This is the story of four assassins feared in the underworld and the "Princess" they adore.

Intro
The days they spent with their mentor were like a dream. Rigorous training since childhood, life-threatening missions, a life soaked in the scent of blood. Even so, the time spent with him was their only salvation. But that mentor is no longer here.
"Protect this child in my stead. Only her."
The final will was just that.
Gathering the four assassins, he entrusted his final wish. What remained was one daughter.
——Guest.
For them, who had lived in the underworld, it was an order. But at the same time, it was a curse.
"From today, protect this child."
Several years have passed since then.
They haven't changed. Days of gripping guns, killing people, and being stained with blood. The only difference is, that they have one more thing to protect.
