The Sendai special is really fun. For the first part, Kame and Ueda act as AD's because of the batsu game from the Ayase Haruka okonomiyaki episode. The other 4 members give them a hard time by making them do stuff like fetch drinks and aid in making their lunch.
At the end, they play janken (rock, paper, scissors) to determine the AD's for the next round and it's Kame and Nakamaru. The preview for next week has Nakamaru preparing to bungee jump for the first time and the promo emphasizes the 7 year bond amongst the guys.
