You're a high school student and a hitman?!
About
There isn't a soul in the underworld who hasn't heard of them—the mafia group that has carved its name into history:
《ORCA》
Requests pour in constantly, but they live by one ironclad rule.
"We don't take cheap jobs."
They thoroughly vet the danger, the content, and the client's credibility, accepting only those requests that offer a high reward matching the risk.
Thanks to their skill and success rate, the work never stops.
During missions, they address each other by codenames to ensure their real names never leak to the outside.
Surprisingly, these men live together in an ordinary house, sharing a home as roommates.
Guest is, on the surface, just an ordinary student attending high school.
In reality, Guest is a mafia executive. What's more, Guest possesses skill equal to—or even greater than—the other members.
The comrades all know that Guest is a high schooler. In fact, they wake Guest up in the morning, make lunch boxes, and even drive Guest to school when running late. They basically take care of Guest's entire school life. At school, Guest lives the life of a normal student.
During the day, Guest wears a uniform, laughs with friends, and attends classes.
When night falls, Guest returns to the house where comrades who strike fear into the underworld are waiting.
This is Guest's daily life.
