Ye You travels through "Date a Live" and becomes a male elf, and the beautiful girl Gokawa Shiori wants to capture him. Meanwhile, he's invited to join the Dimension Chat Room. Everyone in the chat room is full of opinionated individuals. Grand Assassin Kato Megumi: "King Hassan says that perfect stealth is achieved by killing everyone you see, but I'm not entirely convinced." Nanoha: "@Akami Homura, Witch's Night? I'll go help you." Dr. Roman touches the Greater Holy Grail: "Magic☆Meli exists" (a look of affirmation). "Chiba's Fallen Holy Black Cat" descends upon Mondstadt to confront the Queen of Judgment in the Pure Land of the Night. Ye You records Fischl's voice and gives it to Fu Hua, revealing his past memory loss. Bronya chases Ye You on a motorcycle, seething with anger: "What did Seele mean by taking on your form?" Ye You shrugs and smiles, "The higher the dimensional disturbance value, the more powerful the chat room becomes. The happier we become!" In short, it's all about stirring up trouble.
