I refuse to look at the synopsis because the name of the anime and the picture both suggest the show is just a fully serious whodunnit about who farted in class that has now entered a second and season after a cliffhanger scene wherein they finally voted to accuse one person but as the vote ends a small rumbling of the rear trombone can be heard and the camera pans across the class room and the accused is nowhere to be seen making it clear the farter was amongst them the entire time.
