6

Retsuko, Gori Buchou, and Washimi attend a yoga session together. Gori Buchou expresses frustration that the class increases her muscle mass instead of helping her slim down. The instructor repeatedly mentions protein, making it difficult to maintain a normal conversation. Meanwhile, Retsuko notices something unusual about the instructor's gender identity, questioning whether the person is actually a woman. The group continues their exercise while dealing with the instructor's strange behavior and the ambiguity surrounding their identity.
