character: tokitou_muichirou, A medium shot from a slightly high angle featuring Tokitou Muichirou alone in a celebratory indoor setting. Muichirou, a young boy with long, straight black hair that fades into aqua blue at the tips and large, misty aqua eyes, wears his dark demon slayer uniform with oversized long sleeves. He is sitting at a wooden table, leaning forward with a soft, genuine smile on his face, his small hands resting beside a decorated birthday cake topped with a single lit candle. Around him, the room is festive, filled with colorful floating balloons in various hues and several wrapped gift boxes with silk ribbons scattered on the table. The background is a cozy, warmly lit room with soft-focus domestic details. The lighting is warm and inviting, casting a gentle glow from the candle flame across his face, with a bright, cheerful color palette and a joyful, celebratory atmosphere.
