Characters
Reina Kagurazaka S-Rank Sequence No. 1 / 3rd Year / Female
[Contracted Plant]
Sunflower-system Special Type "Heavenly Sun Flower"
- Inherent Ability "Repaints space itself into 'daylight'."
[Public Face: Official Profile]
The noble and kind symbol of the academy, she transforms into a cold, absolute ruler during combat. Her gentle and fleeting smile makes her the object of admiration for all students as the "Holy Mother of the Sun."
[Private Face: Hidden Humanity]
Behind the perfect goddess, she carries a deep loneliness due to a harsh past. She prefers succulents and silence in her room to escape the "voices" of plants. Her solace is incognito cafe tours in disguise, but because others keep their distance, she actually has not a single equal friend to eat lunch with.
Seria Shirayuki S-Rank Sequence No. 2 / 3rd Year / Female
[Contracted Plant]
White Lily-system Support/Manipulation Type "White Ice Lily."
- Inherent Ability "Complete simultaneous parallel processing of cryo-control and absolute healing."
[Public Face: Official Profile]
A talented and beautiful young lady who manipulates ice and healing. Boasting overwhelming popularity, she is hailed as the "Saint of the Ice Flower" for her elegant and perfect smile that seems to heal those around her.
[Private Face: Hidden Humanity]
Her true nature is a dark-hearted tactician who exploits the goodwill of others. A reaction to her deep distrust of people, she craves "pure goodwill without calculation." Her possessiveness toward her favorites is insane, exerting mental pressure with a smile while trying to track their schedule minute-by-minute via Floria location data.
Luka Amagase S-Rank Sequence No. 3 / 3rd Year / Male
[Contracted Plant]
Vine-system Enhancement Type "Thunder Wisteria."
- Inherent Ability "Super-physical enhancement and high-speed movement by converting plant energy into lightning."
[Public Face: Official Profile]
A battle-crazed melee specialist who fights with super-physical enhancement. Usually sporting a bright and cheerful smile, he enjoys immense popularity as a "reliable big brother" who looks out for his juniors.
[Private Face: Hidden Humanity]
A hero who crawled up from the slums. A glutton who spends most of his points on heavy meals or treating juniors. His caring nature is real, but at his core, he is a battle-maniac who only feels alive on the brink of death against the strong. He makes his favorites with potential accompany him in training 24/7 even in private life.
Aria Kujo S-Rank Sequence No. 4 / 2nd Year / Female
[Contracted Plant]
Rose-system Manipulation Type "Blue Rose."
- Inherent Ability "Wide-area battlefield control freely manipulating blue rose petals and violent water currents."
[Public Face: Official Profile]
A cool and silent genius who manipulates blue roses and water currents. Beautiful and fleeting like a doll, she has a mentally immature side; when her emotions are disturbed, she loses control of the Blue Rose storm, indiscriminately involving her surroundings.
[Private Face: Hidden Humanity]
Clumsy and appearing cold because she shuts herself in the greenhouse without speaking, but she is super-caring at heart. She has a cute gap, being incredibly weak to cats and offering them cat food with a defenseless smile. When she finds a favorite, she worries excessively about their health, but as they get closer, she panics emotionally and almost loses control of her ability.
Himari Takanashi S-Rank Sequence No. 5 / 2nd Year / Female
[Contracted Plant]
Clover-system Creation Type "Solar Sunflower."
- Inherent Ability "Wide-area control that generates a massive sunflower field across the entire battlefield, explosively boosting ally abilities."
[Public Face: Official Profile]
A wide-area control genius who explosively strengthens allies by generating flower fields. An academy idol figure with excellent communication skills and a brightness that treats everyone equally.
[Private Face: Hidden Humanity]
Having been isolated in the past due to an ability rampage, she strongly wishes to "never let anyone be lonely." She spends many points on gifts for friends, but if a favorite is hurt, her smile vanishes, and she possesses a dangerous streak of raging until the enemy is ash. She hides an intense possessiveness, making aggressive moves via Floria toward those she particularly likes.
Shion Sumeragi Former S-Rank Sequence No. 1 / 2nd Year / Female
[Contracted Plant]
Rose-system Special Type "Black Rose."
- Inherent Ability "Absolute dominance that repaints space itself into her own domain, forcibly weakening and controlling the opponent's ability output."
[Public Face: Official Profile]
The academy's most feared monster, demoted to the bottom rank after numerous scandals. Possessing extraordinary power to forcibly weaken and control others with Black Roses in space, she is an absolute troublemaker who mocks discipline and acts on whim.
[Private Face: Hidden Humanity]
An arrogant absolutist who looks down on everything as a way to kill time due to her precocity. She spends points on entertainment and suspicious catalysts, and tries to drag strong people she likes into her room to dominate them along with the space. However, she is incredibly weak against people who step straight into her heart without fear, hiding a closet wimp side that quickly loses its composure.
