Mimiru's a transfer student from a faraway country. She's a bubbly personality, cute, full of energy, has a vivid imagination and desire for adventure. Her “special ability” is the ability to make friends with almost anyone. Her overzealous however, often goes hilariously too far. When she, Kentaro and Jay get trapped into the magic book, she takes it the most in stride. Maybe she should be more concerned with getting home...

Quiet, sarcastic, composed, and antisocial describe Kentaro Kusanagi. Though very smart for his age, he doesn’t like to push himself more than the bare minimum, which gives people a negative impression of him. He wasn’t always like this, but when his only remaining family disappeared over a year ago, the playful cat with a desire to explore the world like his grandfather became passionless and apathetic. Dealing with Mimiru's shenanigans seems to bring his old self back though

The quiet and polite Jay moved to Suntail with his parents prior to the events of this story and works at the famous Blubyrd’s family bakery. There, the Blubyrds befriended Kentaro’s family, and became close with his first true friend, Kentaro. Shy, easy to startle, and lacking in self-confidence, he is considered a the “scaredy cat” of the group. He’s just overly cautious is all! He seems to be okay around Kentaro and Mimiru, though...

A small but rambunctious chinchilla. She is the daughter of a family that owns a very successful sports drink company, making her family the richest in Suntail, which unfortunately, makes her spoiled, and pretentious. She always wants to be right, and can be sore loser, a product of her parents raising her. She can also be two-faced, showing her cute side one moment, and staring daggers at you the next.

The trio’s homeroom teacher at Suntail Middle School, Sam has lived in Suntail most of his life, having fond memories of his childhood. After his college graduation, he came back to teach. Sam is a big nerd and is an avid gamer, even having participated in online tournaments under an alias. He also loves cartoons and comics, but doesn’t let people know about his game and comic collecting obsessions. It might have something to do with a crush on a certain teacher...

One of the teachers in Suntail Middle School. She’s mature and intelligent, she lives a very active lifestyle, whether it’s teaching multiple subjects at school, rock climbing, morning jogs, or swimming. She likes to keep fit and watch her weight, but ever since moving to Suntail, she's been having problems when it comes to the donuts at the Blubyrd bakery. The students love her because it seems like she can do anything.

The librarian at the oldest library in the town of Suntail, he used to be a good friend of Kentaro’s grandfather too, and feels sympathy towards the pain he feels Kentaro must be going through. Though very knowledgeable of books, he still doesn’t know where everything is in the enormous library he inherited. He tends to be a bit forgetful and bounce around a lot of topics in his soliloquies, unfortunately...

Jay’s father, who works the financial side of the Blubyrd Bakery. He’s a hard worker that sometimes worries too much about making the family business more profitable. Friendly and easily approachable with a sense of humor and a bellowing laugh (usually at his own jokes), James values family above all else, and treats Kentaro like a son.

Jay’s sweet mother, who is a baking genius, and she knows it. Her mini doughnuts are the talk of the town at her Bluebyrd Bakery. Always cheery and optimistic, but when it comes to her son, she worries about his lack of assertiveness, and her over-protectiveness sometimes embarrasses Jay from time to time.

A mischievous strange creature that can manipulate ice magic. No one really knows what it is - a magic snowman? Elf? Maybe a gnome? We may never know the answer, especially since it speaks in its own mysterious language.

A sorceress that can manipulate ice magic, she rules her world with an iron fist, freezing the land and forcing the inhabitants to obey with her army of ice minions. When she speaks, even the air around her freezes. She cares only for herself, wishing to gain more power to control more land and subjugate more servants. She is very knowledgeable of magic, especially of the book that sent Mimiru and friends to her world.
