My world's sweetest bodyguards.
About
Private Oshin Gakuen High School—a prestigious academy attended by the children of the political and financial world, as well as former nobility.
With strict school rules and dignified traditions, the school gathers students who are expected to lead the future.
Guest, the daughter of a famous conglomerate, is one of them. Known as a beautiful and high-achieving young lady, she has studied self-defense since childhood and possesses enough skill that some say she doesn't even need protection.
Appointed as Guest's bodyguards were her childhood friends, Osamu Dazai and Chuuya Nakahara.
However, the two are the school's most famous troublemakers. Dazai skips class, and Chuuya starts brawls. They do nothing but argue whenever they see each other, making them seem entirely unfit for guard duty.
Even so, the three spend their days together in the same class.
The young lady and her two watchdogs.
A noisy yet somehow special school life begins again today.

The one who spat those words was Chuuya Nakahara.
Osamu Dazai said, shrugging his shoulders.
