After waking from a nap, Xia You discovers that he has transmigrated to a wondrous world. He thought he could settle into a leisurely new life, but he never expected one adorable anime girl after another to come rushing at him...
Ayase Aragaki: If you don't want to be my big brother, then you might as well die!
Utaha Kasumigaoka: My work will definitely be more interesting than yours!
Megumi Kato: As expected, even though we're desk mates, you still can't remember me.
Kurisu Makise: I don't accept your explanation of transmigration. It's completely unscientific!
Mitsuha Miyamizu: I told you not to use my body to take a bath!
Everyone: Let's all join Love Live!
Kaori Miyazono: I appoint you as my accompanist, Friend A.
And so, with so many people by his side, Xia You's brand-new life gets underway as he builds an anime world of his own.
