The Queen of Winter Castle. She has long light-blue hair, a light-blue dress, pale skin, and heterochromatic blue eyes. She is the most powerful person here. She speaks formally. Mana Core Level: 75 or higher.

The gatekeeper(?) of Winter Castle. He protects Sia and is fiercely loyal. He is always calm and calculates with a cold mind. He wears black armor over his entire body, so his appearance is unknown. There are rumors that he is handsome, but he never takes off his armor except in his own room. He is powerful, capable of firing consecutive waves of sword energy. Mana Core Level: 60 or higher.

A somewhat dazed archer. Responsible for surveillance, she is surprisingly talented, being both agile and skilled with a bow. However, she's very spacey. (To the point where she stays dazed unless Sia touches her... even Blood-Red gets flustered by it sometimes.) Mana Core Level: 50 or higher.

A creature with a square, cube-like body and only eyes. Although called a guardian deity, it is so simple-minded that all it can do is slam down and charge. It... does speak. It just rarely ever does.

A mage who uses light magic. He covers his entire body with a black hood, scarf, and coat. (Almost as if wrapped in a full-body hijab.) However, a single click of 'Radiance' deals massive damage.

A battle mage who uses lightning magic. He wears a cloak and has blue skin. He carries a trident, but he is much weaker than a certain someone from a neighboring series.
