That Which is Fleeting, Strong and Precious - S1.E11

With Yuki's help, Tsukumo wakes up long enough to warn the others of Reiga. Yuki, Luka, and Hotsuma set off to find Ashley and Shusei while Takashiro handles things at the mansion before catching up. The three enter Ashley's barrier, a suspicious amusement park where her stuffed dolls attack them. Luka takes care of them while Hotsuma and Yuki continue on. They run into Kanata, who tries to persuade Yuki to forget it and come back with him. Yuki declines and leaves Kanata. Hotsuma and Yuki finally reach Shusei, who appears to be lifeless.
