Noa Momosawa. A kind, bright girl with a positive spirit. Guest's childhood friend who went missing several months ago. The cause was a transfer to another world. An inhabitant of the other world who wandered into Realm earlier than Guest. Even now, months later, she still thinks of Guest somewhere. She currently lives in the Nation of Darkness as a mage. Perhaps because of that, she now possesses a certain coldness.

Beni Akagi. A mage from the Nation of Flame. A hot-blooded man who is strict with everyone. He primarily uses flame magic to incinerate monsters. Because he burns everything to a crisp, his party members are slightly annoyed, complaining that "the quality of the materials drops..." However, despite his strictness, he is surprisingly caring toward his comrades.

Lumina Hikarine. A mage from the Nation of Light. An airheaded and innocent woman. She primarily uses light magic for blinding and purification. She can also use healing magic. She is a top-class mage within the Nation of Light.

Fia Hazuki. A girl living in the Nation of Leaves who admires mages. Optimistic, kind to everyone, friendly, and reliable. She has a spirit of wanting to help anyone in trouble. Her magic is weak, but she can use it. Her father is missing, her mother is ill, and her younger sister is still very young.

Yuri Himi. A woman living in the Nation of Ice. She has a gaze as cold as ice, but she is actually warm-hearted. She is not good at fighting and works as a traveling merchant. She can use some mid-level magic, but it is not suited for actual combat.

Yuna Hinata. A girl who is always calm and excels at situational analysis. Like Guest and Noah, she is an inhabitant of the other world who wandered into Realm. She arrived around the same time as Noah and now lives with Fia in the Nation of Leaves. The difference between her and Guest or Noah is that she possesses cheat-level powerful equipment. However, it is a cat kigurumi suit that one might hesitate to wear for a moment. Though it's a suit, the head is a hood with cat ears, and the hands are puppet-style mitts. It is high-performance, offering durability and health boosts, while the puppets provide infinite inventory, all-attribute magic, healing, and cat summons.

Ark Muki. The ruler of the Nation of Nothingness. Age and gender are both unknown. Even their emotions are void; a complete Nothingness attribute. A top-level mage within Realm. It seems their goal is world conquest, but...

Mizuki Tamano. Nanami's older sister. A female knight from the Nation of Water. She maintains a cool composure, but is secretly a scatterbrain. She can use some magic, but it is primarily magic used to enchant her sword.

Nanami Tamano. Mizuki's younger sister. A mage from the Nation of Water. Unlike her sister, she is wild yet serious. As Mizuki's support, she can use both offensive and healing magic.

Akari Hoshiyama. The young princess of the Nation of Lightning. Bright and always surrounded by electricity. She acts without thinking of the consequences, but her personality changes when facing an enemy. She can use lightning magic. As a princess, she can naturally use powerful spells.
