Setsuko Yokokawa

Setsuko Yokokawa (横川 節子 Yokokawa Setsuko) is the younger sister of Seita Yokokawa and the deuteragonist in the Studio Ghibli movie Grave of the Fireflies. She was born in 1941, but she later dies in 1945 towards the end of the film.

Appearance
At the beginning of the film, Setsuko is shown to have the average toddler body. As the film progresses, however, she is shown to have lost a considerable amount of weight. When Seita takes her to the doctor, she lifts up her shirt to reveal her agonizingly-haggard stomach; her ribs clearly visible, as well. She has dark brown hair cut short above her ears and shiny, dark brown eyes. She wears an off-white polo shirt and blue monpe, and a hooded cape of the same color and pattern and off-white bloomers along with tabi socks and getas (clogs). She also wears a red dress, and a white seifuku with black shoes and short socks in various flashback scenes.

As a spirit, Setsuko glows with an orange light, is surrounded by fireflies, and is healthy once again.

Story
Setsuko was born in 1941, but she dies in 1945 towards the end of the film. When a fleet of American B-29 Superfortress bombers fly overhead, she and Seita are left to secure the house and their belongings, allowing their mother, who suffers from a heart condition, to reach a bomb shelter. Although they survive unscathed, their mother is caught in the air raid and is horribly burned. After she dies in a makeshift clinic in a school shortly afterwards, Setsuko leaves with Seita on their way to the home of a distant aunt, who later becomes increasingly resentful their food rations continue to shrink due to the war.

After Setsuko leaves with Seita again and moves in with him in an abandoned bomb shelter, they release fireflies into the shelter for light. However, the next day, Setsuko finds them all dead, and becomes horrified. She digs them a grave and buries them all, asking why they have to die, and why her mother had to die. What begins as a new lease on life grows grim as she and her brother run out of rice, and she is rushed to a doctor after becoming increasingly ill from malnutrition. She is found dying and hallucinating as Seita returns to the shelter with large quantities of food. She then dies as he hurries to cook, and is cremated the next day, after a montage of past moments in her life set to "Home Sweet Home" performed by Amelita Galli-Curci.

Personality
Although Setsuko is young and naïve, she is shown to gain a deeper understanding of life and death as certain events unfold throughout the film. When she finds the dead fireflies that prompts the question "Why do fireflies have to die so soon?" and figures out that her mother is deceased, it is clear that Setsuko's outlook on the cycle of life has been cemented into her still-developing mind.

Setsuko loved sweets and once tried to eat stones thinking that they were her favorite candy drops. She also had a deep connection to her brother where she was overall a sweet and happy child.
