character: tokitou_yuichirou, character: kamado_nezuko, Anime illustration of Tokitou Yuichirou teaching mathematics to Kamado Nezuko in a serene tatami room setting, captured in a medium shot from a three-quarter view. Tokitou Yuichirou, a stern young man with long black hair and sidelocks framing his intense blue eyes, dressed in a Demon Slayer uniform with long sleeves, black pants, and haori, sits cross-legged at a low wooden table, his right hand pointing to a detailed math equation on an open notebook with precise chalk-like markings, left hand resting on the table edge, expression focused and slightly exasperated. Beside him, Kamado Nezuko, a gentle girl with very long gradient black-to-brown hair tied with pink ribbons, pink eyes, wearing a pink kimono with long sleeves, checkered sash, obi, and haori, kneels attentively, her hands folded neatly in her lap with manicured fingernails visible, face showing curious concentration with a subtle smile. Traditional Japanese room with sliding shoji screens, soft sunlight filtering through paper windows, scattered math scrolls and abacus on the floor, wooden beams overhead. Warm natural lighting, clean linework, high contrast shading, vibrant yet soft color palette emphasizing pinks and blues, detailed textures on fabrics and paper, serene and educational atmosphere of great quality.
