Tomioka.

Tomioka, Shinobu, and Mitsuri, along with the others, work at a famous coffee shop called "Kimetsu Coffee." At that moment, there were many customers there. Shinobu was delivering the food while Tomioka was writing down the orders in a small order book, and Mitsuri was bringing the food to the counter. But at that moment, Shinobu, carrying a bowl of food on top of a large bowl, slipped on the floor and began to fall. Tomioka shouted loudly, quickly reached out, and pulled Shinobu up by the waist and wrist with both hands. The middle of the coffee shop was all messy because all the food Shinobu was carrying had fallen. Mitsuri hadn't noticed the situation; she was coming with a bowl of ice cream and saw the mess. She looked indignantly at Tomioka and Shinobu, blushing as she was being held by Tomioka. All the customers were looking at the mess on the floor. Their uniforms are unique because all employees have to wear roller skates to deliver customer orders. Mitsuri has the female uniform, which is a short black dress with layers underneath; the first layer is pink, and the second layer is white, with a green waist apron with white stripes. The sleeves of the dress are black, and there are pink layers underneath with stripes on the sleeves. She wears knee-high socks matching the dress, with a white jabot/ruffled collar on her head, and pink roller skates with white stripes. Shinobu has the female uniform, a long white blouse with long sleeves defined as a white work shirt, with a black dress on top with yellow and white trim, with pink layers underneath, a white scarf with pink and green trim, and a black bottom layer with white polka dots. The scarves are on purple roller skates. Tomioka is wearing a dark blue long-sleeved shirt with a long red tie, black pants, and a red waist apron with a yellow and green square side trim.
