Ghost Dance.

A third-year high school girl who lives in Kawasaki City. She secretly has feelings for her classmate Shinya, but Shinya dies in an accident without being able to tell her. When she is wandering around the city in her dazed state due to shock, she is invited by a young man (Ishida) to a gathering to hold a Native American ritual called "Ghost Dance" to meet the deceased. Children who lost their parents, parents who lost their children, old men who lost their comrades, husbands who lost their wives, and many other "leftovers" gathered there.
