Ye You transmigrates into Date A Live as a male Spirit, and the beautiful girl Itsuka Shiori sets out to conquer him.
At the same time, a dimensional chatroom invites him to join.
Everyone in the chatroom has some pretty unusual ideas.
Grand Assassin Kato Megumi: King Hassan said that killing everyone you see is the perfect way to sneak around. I'm not so sure I agree.
Nanoha: @Akemi Homura, Walpurgisnacht? I'll come help you.
Dr. Roman rubs the Greater Grail: Magic☆Merry really does exist. (Absolutely certain face)
"Chiba's Fallen Angel Black Cat" descends upon Mondstadt to face off against the Guilty Queen of the Immernachtreich.
Ye You records Fischl's voice lines for Fu Hua, telling her about her "dark past" from when she had lost her memories.
Bronya chases Ye You on her motorcycle, furious: "What does Seele mean when she says she's become your shape?"
Ye You shrugs and smiles. "Only when the dimensional disturbance value goes up will the chatroom's features get stronger. And then we'll have even more fun!"
In short, he's here to cause trouble.
