character: tokitou_muichirou, A medium shot, eye-level anime illustration featuring Tokitou Muichirou centered in a celebratory indoor setting. Muichirou is a young boy with long black hair that fades into aqua tips, aqua eyes, and a gentle, happy smile on his face. He is dressed in a traditional dark Demon Slayer uniform with long, oversized sleeves, sitting behind a small table. His small hands are clasped together in excitement as he looks at a delicious birthday cake topped with a single lit candle placed directly in front of him. The room is decorated for a birthday party, with colorful balloons floating in the background and a neatly wrapped gift box with a ribbon sitting beside the cake. The lighting is warm and cozy, with the candle flame casting a soft glow on his face. The color palette is bright and cheerful, with a soft-focus background that emphasizes the joyful and intimate mood of the celebration.
