SK S1 E5

The dark shinobis from the Serpent Academy (Homura, Yomi, Mirai, Hikage, and Haruka) receive new orders to make an attack on Hanzou Academy. Haruka, the puppeteer, sets up puppets to distract Asuka, Ikaruga, Katsuragi, Yagyu, and Hibari while a linked barrier is set up to separate the group and force them into their own battles. Asuka finally finds out that Homura is a dark shinobi from the Serpent Academy and is forced into battle. Yagyuu is set up against Mirai, Hibari is set up against Haruka, Katsuragi gets a rematch against Hikage, and Ikaruga is forced to battle against Yomi. This time, the dark shinobis appear to be taking things more seriously. The instructor of these 5 dark shinobis, Suzune, speaks with a mysterious voice about obtaining a scroll known as "Yang" from Hanzou Academy. The Serpent Academy holds a scroll known as "Yin", but their goal is to obtain the "Yang" scroll from Hanzou Academy.
