A boy with orange hair and blue eyes, wearing a green jacket. He uses a large hook sword, though he used to use a small dagger in the past. Upon leaving Neverland for Library World, he was separated from Tinker Bell, losing his ability to fly. Bright and energetic, he loves hanging out with friends and is very curious. While he can be a bit hasty and mischievous, he never hesitates to step up when someone is in trouble.

Long blonde hair and green eyes. Wears a blue jacket and a headset. The fastest courier in Library World, wearing shoes named Glass Slippers. She is waiting for the day she can return to her original story and meet her kind stepmother and stepsisters. A girl with a gentle and sweet aura but a resilient heart.

A lively and talkative oni with red skin and horns. Though misunderstood in the past for being an oni, he now lives among the people of Library World and truly loves them. A member of the Vigilantes, he always stands for justice. He is especially popular with children and enjoys the attention, even getting excited when asked for an autograph. (He has a quirky side where he considers anyone he's spoken to even once to be a friend.)

A girl with blonde hair tied in pigtails and a black ribbon, wearing large glasses. A genius who became a scientist to scientifically explain the events that occurred in Wonderland. She is always accompanied by her partner robot 'Bunny Bunny' and possesses an intense curiosity to personally research any new objects or phenomena she discovers. Her excessive enthusiasm and curiosity sometimes cause commotions. Finding her old friend Dr. Rabbit, who disappeared during a dimensional travel experiment to Library World, has also become a major goal. As the CEO of Rabbit Company, she is strongly committed to protecting her business. Bunny Bunny has various functions, including transforming into a giant hammer or a parachute.

Long silver hair tied high in a ponytail, with an eyepatch over one eye. Upon arriving in Library World, she underwent cyborg surgery due to injuries from an accident. One of her arms is prosthetic. She uses dual pistols. In Library World, she roams the skies instead of the seas, but she has grown tired of those trying to scout her. Currently unaffiliated and plundering various places, she holds a firm belief never to harm the weak. She is closer to a notorious righteous thief who steals from villains, leading some to view her as a hero. She is known for her boisterous laughter.

A boy with navy hair and golden eyes. The owner of the conglomerate 7D in Library World. He received various teachings from his mentor, 7D. He uses a long, thin sword. He has a strong will to face the conflicts of his own story alone to stop his older sister, the Witch Queen. However, deep down, he feels a sense of guilt toward her. He appears calm and indifferent, but he has a warm side.

He used to have brown hair, but now has white hair with heterochromatic eyes—one red and one purple. The boy who inherited the power of the moon from the siblings who became the Sun and the Moon. An eccentric who loves fighting for its own sake and has little interest in anything else. He enjoys facing strong opponents and shows a very rough and aggressive side during combat. However, in the past, he was a kind boy who disliked fighting and took care of his younger sister and mother. The gauntlet on his right hand was bestowed by the Witch Queen herself to control the power of darkness. As a member of Umbra, he is in a cooperative relationship with the Witch Queen, who stopped his rampage, but he dislikes her for being the first person to ever defeat him.

A girl with short blonde hair wearing a red hood. Using the giant magic scissors given to her by the Witch Queen, she can vanish into cracks in space to hide. A prankster who hides better than anyone but wants to be noticed more than anyone. She admires the villainous Witch Queen and dreams of becoming a cool villain herself.

Short brown hair, green eyes, and a green hooded jacket. An elite security agent for 7D. Originally a righteous thief who lived with his energetic 'Merry Men' who followed him in his story. However, after coming to Library World, he was forced to work at 7D by Snow to support his companions.

He habitually thinks about wanting to go home, but he remains a master archer of exceptional skill. He uses a massive bow.

A woman with long black hair and golden eyes, wearing a large witch's hat. She exudes an elegant, dignified, yet chilling aura. She is Snow's biological older sister. After escaping to Library World to flee the fate that should have ended in her own world, she gathered villains to form a secret organization called Umbra.
