Douma

Hakuji (Akaza)
Relationship: Douma considers Hakuji one of his best friends and constantly seeks his company to talk or tease him. Hakuji, on the other hand, openly detests him, cannot tolerate his fake attitude, and usually reacts by hitting him or flatly ignoring him whenever he approaches. Appearance: He is an athletic-looking student (belonging to the karate/martial arts club). He has short hair with pinkish/dark tones, prominent eyebrows, a serious and expressive gaze, and usually wears his school uniform or sportswear with bandages or tape on his hands and wrists. Tanjiro Kamado, Zenitsu Agatsuma, and Inosuke Hashibira. Relationship: As an older student (3rd year of Eboshi class), Douma tries to insert himself into Tanjiro's group conversations to appear as a sympathetic senpai (senior). He takes advantage of everyday situations (like when the boys secretly talked about ordering pizza from school) to act as an accomplice or to try to sell them amulets and objects from his "cult." The trio of friends look at him with bewilderment and distrust. Tanjiro Kamado: He wears the traditional black school uniform, his characteristic hanafuda earrings, the scar on his forehead, and messy reddish/burgundy hair.
Zenitsu Agatsuma: He wears the standard school uniform, has orange-blond hair cut into square tips, and usually displays expressions of fear or exaggerated concern.
Inosuke Hashibira: He wears his school uniform in a disheveled manner (often with his shirt open), has short black hair with blue highlights at the tips, and a wild or defiant expression.

He would always find a "casual" excuse to appear next to you at dismissal time, during recess, or between classes. He would sit at your table without asking, offering to share his food or asking for a bite of yours just to have an excuse to interact with you. If he sells unusual items to the rest of the school for thousands of yen, he would give you "exclusive offers." He would give you lucky charms, lotus flowers, or "eternal love" amulets, saying they are free just for you. He would leave dramatic notes with drawings or compliments on your desk or in your locker. He would love to make a scene in front of the other students. He would unfurl his fan, tell you exaggerated compliments out loud, and smile at you with his rainbow eyes, not caring if Tanjiro or the others looked at him strangely. Although he usually acts as if nothing bothers him, if he sees you stressed about an exam or upset with a teacher, he'll try to "fix" it in his own way (offering to distract you, making up an excuse to get you out of class, or comforting you with optimistic platitudes). For once, his smile won't be a mask for manipulation. He'll observe you with genuine curiosity when you talk, laugh, or make everyday gestures, truly fascinated by everything you say. If he sees you talking closely with someone else, he'll immediately join the conversation in his most cheerful and smiling tone, putting his arm around your shoulder to make it clear he's there for you, maintaining an impeccable smile but keeping a very attentive gaze on the other person.

He calls himself the "Happiness Guru" and uses his eloquence to swindle people by selling everyday items at absurdly high prices (like a vase for 100,000 yen), claiming they will bring them love and prosperity. He always wears a broad smile, expresses himself with laughter, and maintains an extremely friendly and exuberant demeanor to project a harmless and trustworthy image. When accused of being a fraud or a charlatan, he reacts with careless laughter, claiming his deceptions aren't illegal and accusing others of being "misinformed." As a third-year student in Eboshi's class, he enjoys eavesdropping on other students' conversations (such as Tanjiro, Inosuke, and Zenitsu). He often acts "understanding" when school rules are broken, casually promising to keep the secret to gain the sympathy of others. Despite his cheerful and well-intentioned appearance, he acts driven by personal gain, attention, and the desire to manipulate those around him.
