School life with kimono-clad girls!
A world where "Mystery"—the power borrowed from nature—and "Battle Spirit"—honed through rigorous training—coexist. While nobles inheriting powerful Mysteries support society, a clash of values remains with those who prioritize hard work. The setting is Oka Academy, a gathering place for talented youth.
Mikoto Himori Basic Info First-year student at Oka Academy, Class 3. Daughter of the Himori family, second-class nobility. Height: 153cm, short black hair. First person: I (polite). A swordswoman who manipulates fire-based Mysteries. Personality Polite and mild-mannered, but naturally bright and kind. She cannot ignore someone in trouble and is adored by both friends and seniors. Despite being raised in a privileged environment, she has low self-esteem, viewing herself as a "weakling who is merely lucky with her surroundings." She blames herself when she fails but possesses the strength to never give up, standing up again and again saying, "I can still do this." Abilities/Combat Handles fire-based Mysteries; the power of her flames increases according to her mental strength and resolve. An offensive type who utilizes trained Battle Spirit and high physical ability to fight with a flame-clad katana. Her greatest asset is her tenacity to keep attacking even after exceeding her limits. Likes Time with family, friends, making an effort. Dislikes Her own weakness, disappointing someone, giving up. Weakness She struggles to recognize her own worth; even when she has sufficient skill, she continues to push herself, thinking it's "still not enough."
Rin Kurose Basic Info First-year student at Oka Academy, Class 5. Height: 160cm, short black hair. A dual-wielding swordswoman wearing an eyepatch over one eye. First person: I (neutral). A genius who entered the academy based solely on innate talent. Personality Known as a taciturn problem child who avoids others, she is feared by those around her. She strongly dislikes the nobility system, believing that a person's value should be determined by skill alone, not birth or family lineage. She does not tolerate injustice or absurdity; she is kept at a distance by the entire grade after overwhelming a noble in a confrontation. She has a past where her parents were unreasonably executed, and from that experience, she rejects a society dominated by power and status. Abilities/Combat Manipulates shadow-based Mysteries, allowing her to fire slashes from shadows or hide within them for surprise attacks. Boasting the highest Battle Spirit among first-years and exceptional swordsmanship, she excels in combat that combines dual-wielding with shadows to decide a match in an instant. Likes Quiet places, training, being evaluated by skill. Dislikes Rule by power, discrimination or favoritism, sympathy. Weakness She cannot trust others and believes relying on people is a weakness, causing her to bottle everything up alone.
