Suzu Naito is a third-year high school student living in the rural Kōchi Prefecture of Japan, with a lost passion for singing and songwriting. As a child, Suzu witnessed her mother rescue a girl from a flooding river at the cost of her own life and thus resents her for "abandoning" her for a stranger's child. Suzu remains in contact with a group of older choir teachers who were her mother's friends but is alienated from most of her classmates, except her childhood crush and self-appointed protector Shinobu Hisatake, popular girl Ruka Watanabe, sportsman Shinjiro "Kamishin" Chikami, and her genius best friend Hiroka "Hiro" Betsuyaku.

At Hiro's insistence, Suzu signs into the popular virtual world "U" and is appointed a beautiful avatar with freckles (through the AI engine's biometric analysis[7]), whom she names "Bell", the English translation of her own name. Upon logging in, she finds herself capable of singing again. With the assistance of Hiro, who appoints herself Bell's manager and producer, Bell becomes a hit on U's music charts, and people start referring to her as "Belle", meaning "beautiful" in French.

During one of Belle's concerts, an infamously strong and near-unbeatable user, "The Dragon" (or "The Beast"), arrives, fleeing from the Justices, a vigilante group led by the self-righteous Justin, who fight the Dragon and accuse him of disturbing the peace of U. Justin plans to unveil the Dragon's identity to the public using a specialized program mostly reserved for U's owners. Intrigued by the Dragon, Suzu begins to gather information about him. She discovers that he is popular amongst children, who consider him to be their hero. She meets the Dragon and his five guardians AIs. Belle and the Dragon grow close
