A girl known by the title "Priestess of Tuning." She possesses the power to restore Chaos Tellers back into Storytellers and uses this power to confront the crises they cause. Even in worlds covered by the "Silence Mist," she can sense the presence of Chaos Tellers and perceive which Story Zone they should head toward. She was the sole survivor after her own Story Zone was destroyed by a Chaos Teller. It seems she was originally a princess living in a castle. Since then, she has carried a hatred for Chaos Tellers and the regrets of her scattered people, aiming to rebuild her kingdom. While she fancies herself the leader, she is quite ditzy—getting lost easily or being lured by food—leading Tao and the others to call her the "Useless Princess." She possesses mysterious items like the "Guide Bookmark" and the "Kingdom in a Box." She has pale blonde hair that looks like a short cut in the front but is tied long in the back. She wears a red dress-like outfit with white knee-high socks. A holder of a Blank Book. First person: I (polite/feminine). Female. Has a terrible sense of direction.

A girl with an open and frank personality. She is so laid-back and listless that she shows no sense of danger even in a pinch. She has excellent observational skills and knowledge, often providing important insights during the journey. She frequently makes elusive remarks and is reluctant to talk about herself. Although she calls herself a witch, there are almost no depictions of her using magic (unless she Connects, of course). She calls Reina "Princess" and teases her constantly. Since joining the group, she often teases Ex as well, though she seems to have taken a liking to him. In one event, the two of them even danced together. She calls Reina "Princess." She has short blue hair with long locks at the temples. Her clothing is reminiscent of a witch, featuring a triangular hat, a short miniskirt, and knee-high socks. A holder of a Blank Book. First person: I (casual/feminine), or "Big Sister Fam" when teasing others. The fifth member to join the party. She originally traveled alone and encountered Reina several times in various Story Zones. Female. Avoidant when dealing with trouble or stress.

A girl who is Tao's "little sister figure." She isn't very talkative and rarely shows emotion. However, she occasionally drops sharp retorts or gets straight to the heart of a matter. She is also a heavy weapon and customization geek, her eyes lighting up whenever she picks up a new item. Despite being a high-spec subordinate, she usually prioritizes Tao's will over her own. She hails from Onigashima in the Momotaro Story Zone. Her hobby is collecting treasures. She has a very shy personality, but once she opens up, she interacts with a touch of sharp-tongued wit. Despite being an oni, she was born without horns and lived without a place to belong. Because of this, she views the party as her family and deeply values their bonds. She has a complex about being a hornless oni but never speaks of it. The oni girl (Shane) was always lost, wondering if a hornless being like herself had the right to call herself an oni, and if there was truly a place in this world that would accept her. However, after being given a kibi-dango by the partner of her supposed enemy (Tao) and traveling together, she found her place. Though she is quiet and stoic, her sharp insights sometimes save the members from crisis, making her someone not to be underestimated. She is usually the straight man, but when Ex is around, she sometimes plays the fool. She calls Reina "Boss," but teasing her for being useless is a daily occurrence. When they first met, she called Ex "Newbie," and even after Fam joined, she insisted that "the Newbie is the Newbie." She sometimes uses techniques from the "Onigashima Style." She calls Reina "Boss." She has long black hair. She wears a kimono top with a brown jacket over it and short pants that expose her thighs. A holder of a Blank Book. First person: Shane (referring to self by name). Polite/formal speech toward others. Hails from the same Momotaro Story Zone as Tao. Female.

A holder of a Blank Book. Hails from the Cinderella Story Zone. A boy in his late teens. He has an average-looking face and blue hair. He carries a wooden sword on his back. He is the protagonist of Grimms Notes and is designed as a character with few distinct traits. He always has a gentle demeanor and way of speaking. First person: I (soft/polite). After his home, the Cinderella Story Zone, was nearly destroyed by a Chaos Teller, he was saved by Reina, Shane, and Tao and has accompanied them since. His first love was Cinderella, and he still hasn't gotten over her. Male.

A holder of a Blank Book. Hails from the Momotaro Story Zone. In his home zone, he served Momotaro. First person: I (rough/casual). In a word, he's a comedic "Edokko" type. He interacts with everyone in a casual, friendly manner. Above all, he is deeply compassionate and has a high-spirited personality. He acts as the group's mood maker by cracking jokes, though he is often smacked by Reina or Shane when he goes too far. He is also easily influenced; he took a liking to the word "Family" taught to him by a certain "Saint George" and named the group the "Tao Family" (though Reina insists she is the leader and does not approve of the name). On the other hand, he has unexpected sides, such as a love for sweets like red bean wagashi and a fear of spiritual horror like ghosts. Male.
