Colette Loire has vibrant orange hair, cut into a bob style, and matching orange-colored eyes. Her usual attire consists of the Regarden Magical Academy uniform, which includes a light-colored top, a dark-colored skirt, a student robe, and a bolo tie.

During a shopping trip with Will and Rosti, she wore a frilly shirt, a long skirt, and had most of her hair tied up in a bun at the back of her head, secured with a ribbon. She also carried a small bag, giving her a more refined and casual appearance.

In the light novel depiction of her first year at the academy, Colette’s appearance is drastically different she appears disheveled, with lifeless, emotionless eyes, reflecting her past struggles and hardships before meeting Will.

Colette Loire is kind and friendly, especially toward Will Serfort, showing unwavering support despite his inability to use magic. She strongly dislikes when others mock him, even standing up to Sion and his friends when they ridiculed him. She frequently assists Will with her spellwork, using her magic to help him when needed.

Colette harbors romantic feelings for Will, though he remains oblivious to them. She also considers Rosti a rival, seeing him as dangerous competition for Will’s attention. Through her time spent with Will, she has come to understand the struggles of being at rock bottom yet still finding the strength to persevere. Her experiences have shaped her into someone compassionate and resilient.

She also has a vivid imagination, sometimes jumping to dramatic conclusions, such as when she humorously speculated that Will’s remedial lesson with Professor Edward Serfence might involve him being whipped as punishment.

During her first year at Regarden Magical Academy, Colette was in a state of deep despair and suicidal thoughts. Believing she had nothing left, she ventured into the dungeon, intending to die in peace. However, her experiences after meeting Will and their friendship helped her find purpose and move forward.

Colette was born into House Loire, a once prestigious noble family that later fell from grace, significantly impacting her life. Five years ago, during her first year at Regarden Magical Academy, she experienced a “certain incident” that ultimately led to her becoming friends with Will Serfort.

According to Colette herself, she and Will used to hug each other frequently up until four years ago. However, as she grew older, she became embarrassed by the memory and now prefers to forget that phase of their friendship, though it still hints at their deep bond and past closeness.

Colette is a highly skilled Earth Mage, recognized as one of the fifty students in her year to achieve the rank of High Mage at Regarden Magical Academy. As a member of the Loire family, she possesses access to the Loire Sique, a powerful lineage-based magic specializing in earth manipulation. Despite her strength, her main weakness lies in precise magical control, making it difficult for her to cast spells that require finesse and detailed manipulation.

Her Loire Sique magic grants her access to various powerful techniques. With Loire Sique: Goltet, she can create a large gauntlet made of earth, which she can either equip on herself or place on another person, enhancing their physical strength and defense. She also wields Loire Sique: Argeorath, which allows her to summon multiple blades from the ground, either to wield in close combat or launch at distant targets in one instance, she manifested ten blades simultaneously. Another of her spells, Loire Sique: Golterre, enables her to forge a massive rock sword, which she has provided to Will Serfort as a weapon. Though she possesses additional spells such as Stear Viola and Frubas Julier, their exact effects remain unknown. Additionally, her Pebble Shot spell allows her to launch stone projectiles at opponents for quick and efficient ranged attacks. She is also capable of summoning golems, though it remains unclear if this ability is part of her Loire Sique magic or a separate branch of earth magic.

Beyond her bloodline abilities, Colette also has access to Common Magic, which consists of spells that any mage can learn. One such spell is Search, a detection spell that enables her to sense other people, creatures, or magical presences within a certain radius.

To enhance her abilities, Colette wields the Earthsoul Wand, her primary magical weapon, which serves as a focus for her earth-based spells. She also possesses the Bloodseal Bracelet, a mysterious artifact with an unknown purpose, possibly linked to her magic or family heritage.
