when Mamoru-san is on the video, I keep thinking "Why is he look so humble and... calm..?" Then, he answered Washizaki-san's call. . . . "Aa~h, so it's his preparation before his action..~ now I know~"
At 5:14 Mamo said "can you do a call for Arashi?" and the audiences started chanting while you can hear the other casts breaking into a laughter fit and kept saying, "ITS YAMA ARASHI" I JUST REALIZE THAT LMAO
