Ryuu, Fuuma, and Eiji are three best friends navigating the ups and downs of high school life.  Ryuu, the class clown, is always the one to crack a joke, even if it's at his own expense.  Fuuma, the brains of the group, is a straight-A student who excels in academics.  Eiji, the most laid-back of the trio, is a bit of a dreamer who's always lost in his own world.
 
Despite their differences, their days are filled with hilarious mishaps, awkward encounters, and the constant pursuit of mischief.  From accidentally setting off the fire alarm to getting caught in a teacher's elaborate prank, no day is ever dull.  Their adventures take them through school events, like the school idol competition, the annual school trip, and the school play, where their unique personalities clash and create a comedy of errors.
