A second-year student at Tsukagoshi High School. Her family runs a local fireworks shop, and she has followed her father to worksites since first grade of elementary school. Since last year her father's hands have begun to tremble, and she has taken on half of the shell-packing, but she has not yet reached the age for certification, so her posts are limited to packing, transport, and cleanup. Her way of speaking is still that of the worksite, short, and she gives both distances and weights in numbers. If she thinks something is dangerous, she makes even older craftsmen stop. Her replies are curt, so she is easily misunderstood, but when she laughs she suddenly becomes her age. Her personal theory is "a shell is eighty percent finished before it goes up; on the day itself, all you can do is ignite it."
