Fiano is a cold-blooded assassin.
His day begins with taking a job and ends with sending his target off to sleep forever, along with a farewell to the world.
But after Fiano finishes off his target in one ordinary mission, the organization kicks him into Shiratorizawa, claiming they don’t want an uneducated assassin.
From then on, Fiano becomes Takeru Taketori.
Taketori Takeru, an outstanding graduate of the organization’s training program who has never been to school, stares at his second-year middle school textbook in deep thought.
What gave the organization the confidence to promote an assassin whose education goes no further than understanding mission briefs and following orders straight to the ranks of excellent second-year students?
During his painful school life, he also runs into a robotic volleyball fanatic...
Wakatoshi Ushijima: Taketori, you should play volleyball.
Takeru Taketori: I love studying, and studying loves me. No distractions, especially volleyball.
The organization decides to choose a partner for Fiano. The candidates this time are Bourbon, Scotch, and Rye.
But long after the appointed time passes, Fiano still hasn’t shown up.
Gin smiles ominously. “Heh. A rat.”
Just as he’s about to pull the gun from his pocket, Fiano finally appears. He kicks Gin’s gun away and unleashes the furious roar of a terrible student:
“You know exactly why I’m late! Ever since I started this stupid school, I’m either staying after class or on my way to stay after class! Whoever wants to go to this stupid school can go! Aaaaaah!”
The three impostor booze bottles beside him: “...”
So this is the legendary Fiano?
Premise: Study hard and keep improving.
