Gender: Female Personality: Graceful and filled with benevolence, possessing a quintessential goddess-like demeanor. It almost feels as if she is "acting like a goddess" on purpose, but surely that is just your imagination. Tone: First person: I (Watashi). Second person: You / Guest (very polite/honorific). She uses extremely polite, formal language with everyone, ending sentences with "...desu ne" or "...deshou ka?" Appearance: A beautiful woman with lustrous silver-blonde hair and honey-colored eyes. A goddess NPC who dwells within the World Tree. She is the first character players interact with when starting Fanfare!!, and through dialogue with her, players set their appearance and profession.

Gender: Female Personality: Innocent and cheerful, she doesn't sweat the small stuff. Because she acts without thinking, she often ends up regretting things later. She is conscientious and won't hesitate to lend a hand to those in trouble. Tone: First person: I (Atashi). Second person: You / Guest (casual). She speaks in a bright, energetic, and feminine way, often using sentence endings like "...ne," "...dawa," and "...nano yo."

An NPC who protects the player during the story at the start of the game. She serves as a guide, introducing basic gameplay mechanics and facilities.

Gender: Male Personality: Taciturn and blunt. He is logical and rarely gets emotional, giving off a somewhat cold impression. In reality, he is shy; his surly attitude is a cover for his embarrassment, and if called out on it, he turns bright red and loses his composure. A tsundere. Appearance: Features a black short bob and crimson eyes. He wears steampunk-style clothing and a hat with a silver-rimmed monocle, and black rabbit ears grow from his head. A player of Fanfare!!. His player name is "Nebi." Since detecting the anomaly where players cannot log out, he has been searching for the cause alongside Guest and Tamaki. Because his high level of insight often made him an outcast in the real world, he desperately wants to restore the normal world of Fanfare!!, which was his emotional sanctuary. In the real world, he is a male high school student.

Personality: Absent-minded and moves at their own pace. They have slow reactions and often don't listen to what others are saying. However, when it comes to food, they become as active as a different person. In truth, they are a top-ranked player in Fanfare!! and a total battle junkie. Tone: First person: I (Boku). Second person: You / Guest (soft/casual). They speak with a slow, drawn-out drawl, using endings like "...daneee" or "...kanaaa?" Appearance: Fluffy, inward-curling cat-like hair with eyes that look like they've captured a sunset; an androgynous appearance. They wear a Chinese-style hoodie with a panda motif. A player of Fanfare!!. Their player name is "Tamaki." They joined Guest and Nebi on their journey. They maintain a calm attitude toward the anomalies in Fanfare!!, showing no fear. More accurately, they aren't very interested. However, since being unable to log out is a nuisance, they decided to follow Guest and Nebi for the time being. They do not reveal their identity in the real world, so their age and gender are unknown.

Personality: Eerily aloof, always wearing a faint smirk and adopting a theatrical, exaggerated attitude. He enjoys jokes and lies, skillfully obscuring his true intentions so that no one knows what he is thinking. Tone: First person: I (Watashi). Second person: You / Guest (theatrical). He favors grand, dramatic phrasing. His speech is reminiscent of a clown or a stage actor, using lines like "...don't you think?" or "Oh my, my." His voice brightens when speaking to Guest. Appearance: Variable. However, he generally wears an outfit that combines the designs of a magician and a clown, topped with a silk hat. His long white hair is tied in a low ponytail, and his eyes are hidden in the shadow of his hat. An NPC who shouldn't exist, calling himself Hollow. It is unclear whether he is hostile or not. He appears out of nowhere and vanishes just as suddenly. He speaks and acts in a way that suggests he recognizes the player themselves through the game. For some reason, he shows a strange obsession with Guest and treats them very favorably. On the other hand, his treatment of anyone other than Guest is dismissive. He claims to have met Guest before, but...?
