Why not just use skis? Much easier and if they've never done it before I doubt any of them are going to try to get to the point of doing tricks, which IMO is the only reason to go with a board.
Naruse confirmed DEAD. Kyoko in the iglo won the still-competition, but manbagi san flailling everytime was the best overall. I really Start to like and enjoy Kyoko-san in the latest chapters. She's a Sweety and her pure presence funny.
