Yusa, the ice devil, came to Yurine with Jashin-chan. Yusa pleads for her sister, Koji, to look for her because she is missing. Jashin-chan reluctantly called Mei to tell him about Ice's characteristics and asked her to search, but in fact, Ice-chan was brought into Mei's house. Mei is considering how to preserve formalin pickles, taxidermy, mummies, etc. in order to add cute and irresistible ice to his collection.
