Seikai Battle part 1 featured Seigaku infiltrating Rikkai Dai Fuzoku in order to scout out Yukimura. In part 2 Sanada reckons they haven't foiled him in his Yukimura cosplay yet, and he'd be right! Apparently Tezuka is useless without his glasses XD Much silliness is to be had here, well, it's Satoumizu after all!
