Carrot Glace is the main protagonist and de facto leader of the Sorcerer Hunters, a group dedicated to protecting ordinary humans from oppressive sorcerers. He is seventeen years old and is physically characterized by his black hair, which is cut to ear length, and his brown eyes. His typical attire includes a tank top, boots, and arm guards, and he carries a longsword that he rarely uses effectively due to his lack of skill with the weapon.

He was born to Onion and Apricot Glace, both former Sorcerer Hunters, and grew up on Mount Saint Hordic with his younger brother, Marron, and the adopted Misu sisters, Tira and Chocola. His childhood was marked by the disappearance of his mother, who sacrificed herself to protect him from a magical threat, an event that had a profound impact on his family and his relationship with his father. Carrot shares a complex but strong bond with his brother, frequently defending the more feminine-looking Marron from bullies in their youth, and the mutual protectiveness continues into their adult lives.

On the surface, Carrot exhibits a personality that is overwhelmingly lecherous and perverted. He constantly chases after women, bombarding them with an endless stream of terrible pickup lines and propositions for dates or sex, only to be routinely slapped or beaten for his efforts. Despite his persistent and forward nature, he generally respects clear disinterest and will stop his advances, for instance, once he learns a woman already has a boyfriend. His behavior is often the source of comedy within the group, as he frequently trips over his own feet, eats objects off the ground, or has his antics cut short by violent punishment.

Beneath this comedic exterior, Carrot is noted to have a good heart and possesses a strong sense of justice. He grew up in a world where normal humans are often enslaved and mistreated by sorcerers, and he fights to oppose such injustices. He is fiercely protective of his friends and family, and the only times he exhibits true hatred is when he witnesses people being unjustly brutalized. To his adopted sisters, Tira and Chocola, he feels a strictly familial, brotherly affection. This creates significant tension, as both sisters harbor deep romantic feelings for him. Carrot views a romantic relationship with them as incestuous and is uneasy with the notion, which is the primary reason he so vigorously pursues other women. The sisters, however, interpret his behavior as infidelity and rejection, and they frequently punish him with their whips, a treatment he greatly fears.

In terms of combat ability, Carrot is otherwise the weakest member of his team, possessing no conventional magical power or significant physical strength. His true power lies in two innate abilities: Aranju and Zoanthropy. Aranju is the ability to absorb magic directed at him without suffering its intended harmful effects. This absorption then triggers Zoanthropy, which forcibly transforms him into a giant, rampaging monster. The specific monster he becomes is typically one of twelve forms based on the animals of the Chinese zodiac, though he can access other forms, such as a draconic one, under special circumstances. While transformed, Carrot loses all sense of self and becomes an uncontrollable, mindless beast with no memory of his actions afterward. This transformation is his ultimate trump card, but it also endangers his allies. He must be pacified by his teammates; in the anime, Tira Misu beats him with her whip to force him back to normal, while in the manga, she weakens the monster so Marron can extract the absorbed magic from his body. His survival is also bolstered by an extreme level of luck, which is later revealed to be the self-preservation instinct of the God of Destruction sealed within him.

Carrot undergoes significant development over the course of the story, particularly in the manga. While early on he consistently rejects the romantic advances of Tira and Chocola, he gradually shows hints of hidden attachment and dejection when they are absent. His character arc concludes with him openly professing his love to both sisters. He ultimately marries Tira, while Chocola accepts the marriage and remains determined to be the one to bear his first child. The source of his unique powers is revealed in the late-series lore, which states that each Sorcerer Hunter is the human reincarnation of a deceased god, with Carrot being the reincarnation of Hakaishin, the God of Destruction. This revelation adds a darker, more significant layer to his role as the central hero.
