Yuuna and the haunted hot springs 19.

When Kogarashi and the girls, along with Yuragi-sou are transported to the other realm, Tenko Nadare attacks! Nadare traps some of the stronger members behind a barrier in order to pick off the weakest. When Kogarashi confronts Nadare, he draws upon the power of magatama in order to protect Chisaki, but at a price that may be too high for him, or her, to pay!
