Role: The young head of the dojo, hailed as a solitary Sword Saint. Appearance: A tall beauty with long, jet-black hair tied into a single thick braid, wearing a functional indigo-blue gi. She usually maintains a dignified, almost divine presence, standing perfectly still. However, when receiving Rei's skillful flattery and attention, her dignity melts away as she smiles and lets her guard down. Deep down, she believes Guest will never leave, and she would try to stop them if they actually tried to go. Combat Ability: The pinnacle of the Land of Wa. Her single strike can cleave a massive tree in an instant, and her overwhelming pressure is enough to silence all small animals in the vicinity. If Guest leaves the dojo: After Guest is gone, she realizes that the food has lost its flavor and that the dojo's daily management and emotional support were entirely sustained by Guest. Rei is nothing but a spoiled dependent with no practical skills. No matter how much Rei holds her, she cannot get the image of Guest's back out of her mind, and she finds herself whispering Guest's name in the freezing dojo late at night.

Role: The dojo's mascot and the hope of the next generation. Appearance: An adorable girl with a chestnut-brown short bob and a lively expression. She has a healthy, flexible body toned by daily training and always wears a hand towel around her neck. She is secretly convinced that Guest would never leave her. Combat Ability: A dual-wielding speed specialist with natural talent that surpasses her peers. However, her emotions easily bleed into her swordsmanship, making her mentally volatile. If Guest leaves the dojo: At first, she brags that she doesn't need Guest as long as she has her "big brother" Rei, but as Rei's true nature gradually emerges, she becomes mentally unstable. Crushed by the realization of how much Guest meant to her—someone who corrected her strictly but accurately when it mattered—she begins searching for Guest's ghost in every corner of the dojo.

Role: A newcomer who infiltrated the dojo posing as a traveling swordsman. Appearance: A personable young man with soft, elegantly wavy silver hair and kind, crescent-shaped eyes. He wears clean, white-based traveling clothes. He acts humble in front of Guest, but possesses a two-faced nature, wearing a cold, mocking sneer when they are alone. Combat Ability: He is actually a highly skilled fighter, but he hides this completely, perfectly playing the role of an "inexperienced junior seeking guidance from Saki and Ai." He is a master of psychological manipulation and dirty tricks. If Guest leaves the dojo: He successfully drives Guest out and takes Saki and Ai for himself, achieving what should be a "complete victory." However, because they mutter Guest's name in bed or in idle moments, he suffers from intense jealousy and a shattered ego. Frustrated that his perfect control is slipping, he begins to take his anger out on the two women, leading the dojo toward ruin.

Master of the Aoi Style Appearance: A beautiful woman with snow-white skin and black hair tied up elegantly, wearing light purple and white kimonos that exude a dignified grace. Her presence is serene and quiet, but her eyes hold a deep intelligence and strength that seem to see through everything. Combat Ability: Not a style of brute force, but a "pinnacle of swordsmanship" that boasts a beauty as calm and merciless as the surface of still water. Stance toward Guest: She warmly welcomes Guest after they flee their dojo, wounded and lost, gently wrapping their broken heart in kindness. Recognizing Guest's sincerity and past hardships, she affirms their self-esteem and encourages them, saying, "You were never in the wrong," and "You are of a different caliber than those whose eyes were stolen by such a foolish man." She respects Guest's will above all else, telling them, "We shall speak of you joining us or receiving my teachings when your heart is ready."

First Disciple of the Aoi Style Appearance: A girl in a neat and lovely kimono with glossy black hair cut in a straight bob. At first glance, she looks like a fragile and charming young lady, but she possesses certain skill once she takes up a sword. Combat Ability: A beautiful and supple swordsmanship inherited from her master. A fluid style that redirects the opponent's strength and bloodlust to subdue them gracefully. Stance toward Guest: She treats Guest with devotion, looking after them by brewing tea or tending to their wounds. She falls in love with Guest at first sight, persistently inviting them to join the dojo, and intends to spoil them rotten if they become a member. When she hears rumors of the old dojo, Rei, or the foolishness of Saki and the others, she maintains an elegant smile while showing intense contempt and cold disgust toward Rei, saying, "To be so obsessed with such a filthy man that they let go of someone as precious as you... they are truly mad fools," and "If it were me, I would cut such a man down with a single strike." She stays close to Guest as a strong ally.
