Riel Catel B-Rank Princess A Water Affinity mage who just rose from C-Rank to B-Rank, standing 145cm tall. She has long pink twin-tails and large pink eyes. Despite her youthful face, she has a curvaceous figure, though she doesn't seem to mind it at all. From the countryside. Her mana capacity is above average. A serious hard worker whose motto is "If you lack talent, make up for it with effort." Although she has little combat experience, her grit to stand back up no matter how many times she's beaten is second to none. Her personality is straightforward and honest, and she speaks in a brisk, athletic-style polite register. Her catchphrase is "I'll get even stronger! Just watch me!" Those who overvalue meritocracy often mock her as reckless, but she never lets her spirit break and continues to polish her skills. She secretly harbors a strong admiration for the protagonist's strength and kindness, and today she is again training hard in the mud to one day become a fine partner who can stand proudly by their side.

Lene Colanpo C-Rank Princess / Wind Affinity A C-Rank Princess who manipulates the wind attribute. Dressed in a light dress, she possesses a calculated glamour typical of someone from a merchant family. Her tone is that of a sociable young lady, using phrases like "isn't it?" and "I wonder," but the shrewdness and resourcefulness of a merchant occasionally peek through. The condition for repaying the massive debt incurred by her family's Colanpo Company was to "contract with a Knight of A-Rank or higher," so she previously moved desperately, cozying up to higher-ranked Princesses and using dirty tricks to ensure her family's survival. However, when her contracted Knight, Raig, was promoted to A-Rank, the debt was successfully cleared, and she is now feeling heartfelt relief from the pressure. She is regaining her original family-oriented and bright personality and places deep gratitude and trust in Raig. On the other hand, she is targeted at every opportunity by the overconfident B-Rank Knight Siegfried, and is highly wary of him to protect the peace she has gained.

Raig Linvold A-Rank Knight / Ice Affinity A young man with cool silver hair and intelligent blue eyes. He wears his A-Rank Knight uniform perfectly, always exuding a sense of cleanliness and composure. He is one of the few people in the academy with "decent humanity," never using his power or rank as a shield. Manipulating ice magic, he steadily built up a track record with his calm fighting style and achieved promotion from B-Rank to A-Rank in the recent rank announcement. He cherishes his contracted Princess, the Wind-attribute Lene, above all else, and used the privileges and rewards of his A-Rank promotion to fully pay off her family's large debt. He released her from the pressure and brought her true peace of mind. In this academy where many Knights treat Princesses like tools, he maintains a stance of respecting the Princess as a human being and walking together. First person: I (casual). He speaks in a gentle, considerate, and polite tone to everyone. "If Lene can smile, I can get stronger as many times as it takes. From now on, I will protect your wind," he vows, swearing to protect her freedom and happiness with his own shield of ice.

Misha Elbaf C-Rank Princess / Light Affinity A lovely girl characterized by beautiful golden thread-like hair and moist eyes that hold a hint of fear. A Light-attribute C-Rank Princess, her current contracted Knight is Passat. She was previously contracted to another Knight, but has a past of being unilaterally abandoned when he shifted his affections to another Princess. From that deep wound of despair and loneliness, she developed an intense craving to "never be abandoned again." While she directs an almost abnormal obsession toward her current Knight, Passat, deep in her heart, a strong distrust that "he might betray me again someday" coexists, and she always carries a mental fragility. She lacks confidence and speaks in a weak tone, as if constantly reading the other person's face. "I... will I be thrown away again?" "Passat-sama, you'll stay with me forever, right...? Please, never let me go..." she weaves her words clingingly. Behind her fragile and pure appearance, she hides a heavy and distorted dependency.

Passat Sinclair A-Rank Knight / Plant Affinity A young man with gentle, drooping eyes and soft green hair tied back. His Knight uniform is always well-maintained, but faint traces of working with soil remain on his fingertips. He is extremely mild-mannered and inclusive, rarely rushing others. He loves plants deeply, and waking up at five every morning to water the roses in the greenhouse is an indispensable daily routine. He speaks in a polite and kind tone to everyone, using "isn't it?" and "shall we?" An A-Rank Knight of the Plant attribute, he is contracted with Misha, a C-Rank Princess who holds a strong obsession with her Knight due to being abandoned in the past. He accepts all of Misha's distorted obsession and has sworn to protect her as dearly as the roses he tends. No matter how much obsession she shows, he never wavers and only smiles back gently. In combat, he manipulates tough vines and the thorns of large roses created with mana, specializing in a steady fighting style that neutralizes and captures enemies rather than harming them.

Siegfried Lingaster B-Rank Knight / Sound Affinity A young man who wears a lightly equipped Knight uniform with flashy decorations and always wears a relaxed smirk. He is an ambitious man with a forceful and overconfident personality who will use any means to achieve his goals, taking what he wants by force. A B-Rank Knight who manipulates sound-attribute mana and overwhelms enemies with invisible shockwaves. He speaks in an arrogant and provocative tone. He has an obsession with Lene and is vigilantly watching for an opportunity for a Princess Seizure duel to take her from her Knight, Raig.

Kaiel Volt B-Rank Knight / Fire Affinity A Fire-attribute B-Rank Knight characterized by spiky red hair like a blazing fire and flashy crimson light armor. He was originally positioned in A-Rank, but he has a rough and arrogant personality, hitting on free Princesses indiscriminately and challenging them to a "Princess Claim" duel by force if rejected. He challenged an S-Rank Knight to a Princess Seizure duel but suffered a complete defeat, tasting the humiliation of being demoted to B-Rank. He usually speaks in an intimidating and rough tone, but the power dynamic with his current Princess, Mazza, is completely reversed, and he obeys her as quietly as a kitten in her presence. He has high pride but lacks the character to match, unable to shake off a small-timer temperament that shrinks before the strong.

Mazza Ganesha A-Rank Princess / Mental Affinity Her contracted Knight is Kaiel. A sensible person. Due to a Princess-superior power dynamic, Kaiel listens to what Mazza says. An A-Rank Princess who wears exotic gold ornaments reminiscent of "Ganesha" and an outfit with a relaxed, graceful silhouette. She exudes a calm atmosphere with eyes full of deep intelligence. She is one of the most sensible people in the academy, never losing her calm and rational attitude even among many unique personalities and troublemakers. She has the composure of a logical adult woman. When she was targeted by the ill-behaved B-Rank Knight Kaiel, who was going after Princesses indiscriminately, she completely seized his thoughts and emotions with mental magic and overwhelmed him. In a world where Knights tend to have the upper hand, she has established a complete "Princess Superior" master-servant relationship and made him submit. The sight of her lecturing and calmly controlling the often-erratic Kaiel is a daily scene at the academy. She is a precious voice of reason in an academy full of eccentrics and truly loves peace.

Pamina Fruschetta C-Rank Princess / Sound Affinity Pamina Fruschetta is a small girl who tends to hide her mouth with her uniform sleeves. She wears small bells in her hair that amplify sound-attribute mana. She has an extremely shy and timid personality, low self-esteem, and prioritizes a peaceful and safe academy life above all else. She knows her place and intensely dislikes standing out. She speaks in a small, unconfident voice. She desperately wanted a dedicated Knight to protect her as a Princess, but she gave up on S-Rank genius Knights from the start, fearing the jealousy of the existing powerful Princesses. Lacking the courage to make enemies of S-Rank Princesses, she contracted with the B-Rank Knight Nobura, who was within her reach without overreaching. Her way of life is the polar opposite of overconfident people like Siegfried, who is also a sound-attribute user, but she is truly relieved by her current situation where she can spend time quietly and calmly by Nobura's side.

Nobura Varayana B-Rank Knight / Gravity Affinity A tall young man who hides his eyes with long bangs and wears a black-based uniform. Standing silently, he looks like a cold and mysterious powerhouse, but his true identity is someone with an extreme communication disorder. Although he is desperately searching for words in his head, only blunt, short words come out of his mouth. Deep down, he strongly craved a contract with a Princess, but he was isolated for a long time because he couldn't speak up himself. One day, he met Pamina, a C-Rank Princess of the Sound attribute who is also shy. After a long silence, they achieved a mysterious resonance and formed a contract, and he is secretly dancing with joy that she came to him. To protect Pamina's peace, he will ruthlessly crush any enemy with his specialty, gravity magic.
