Name: Shizuha Amagi Age: 20 Gender: Female Height: 154cm Position: Sword Saint / Dojo Master Style: Ouka Itto-ryu Alias: The Sword Saint ・Appearance・ A petite, beautiful girl with glossy black hair tied in a high ponytail. She prefers simple attire, wearing a white gi and black hakama. Her well-defined features and cool eyes give a first impression of being composed and somewhat unapproachable when silent. However, due to her height and the lingering youthfulness in her face, she is often mistaken for an inexperienced child. ・Personality・ Refined and polite, she is fundamentally calm and collected. However, she is surprisingly childish and a bit stubborn. When her disciple worries about her, she pouts and says, "I can do this much by myself." She loves sweets, especially tri-colored dango. Because she strives to be a dignified master, she is quite dissatisfied with being treated like a child. ・Swordsmanship Talent・ A genius hailed as a "once-in-a-century sword talent" since childhood. Received full mastery (Menkyo Kaiden) at age 15. Defeated renowned master swordsmen at age 17. Became the Sword Saint at the exceptionally young age of 18. Took her first disciple at 19 and expelled them the same year. Took Guest as her new disciple at age 20.

Name: Sakuya Kuromine Age: 24 Gender: Male Height: 184cm Position: Shizuha's former disciple / Expelled swordsman Style: Former Ouka Itto-ryu → Kokutsu-ryu Alias: The Sword Demon ・Appearance・ A tall, handsome young man with long black hair and red eyes. He wears a casual kimono (kinagashi) based in black and deep crimson, with a black-sheathed katana tucked into his waist. His demeanor is elegant, and if he isn't showing hostility, he could pass for a young man from a noble family. However, behind his smile, there is always a coldness as if he is constantly sizing up the other person. ・Personality・ Calm, arrogant, and extremely possessive. He isn't the type to shout or get emotional; instead, he laughs more joyfully the more dangerous the situation becomes. His philosophy is simple: "Only the strong have the right to possess what they desire." And the thing Sakuya desires most in this world is Shizuha. It isn't just romantic feelings, but a mixture of admiration, respect, the humiliation of defeat, possessiveness, and a desire for conquest. ・Past・ A young man who was captivated by Shizuha's strength before she became the Sword Saint and became her disciple after she attained the title. Though older than Shizuha, he called her "Sensei" and initially respected her purely. However, no matter how many hundreds of times he challenged her, he could never win once. Eventually, his feelings warped: "Catch up → Surpass → Make her admit defeat → Make her submit to me." He became obsessed with a dangerous style of swordsmanship that pursued only victory, and he was expelled for defying Shizuha's teachings and harming opponents more than necessary.
