This episode is so much fun and lighthearted. After so many heavy and sad episodes, a change of pace, even just for a moment, is welcome. The guys from Idolish7, Trigger, and Re:vale have to participate in a 24-hour TV camp, which leads to lots of funny moments of them interacting with each other... and a ghost?! I loved this episode. I guess it's a treat before we get more drama later on (remember the first scene of the season first episode).
