Muffler ni Ai wo Komete/A muffler, with my love - S1.E32

Momoko, Yuri, and Hinagiku decide to knit mufflers for Yanagiba. When a group of girls gathers together to knit after school, Potamos becomes envious and calls upon the devil Fusuma, who creates a portal in the classroom that traps the other students in an endless labyrinth of linked dimensions. In order to rescue their classmates, Momoko and Yuri sacrifice their knitting projects. The devils interfere with the rescue, and the Love Angels have a close call.
