In “The Girl Who Leapt Through Time,” the train that hits the girl is a Keisei Electric Railway Main Line train bound for Ueno, and in “Erased” there is a meaningful line from the protagonist, “You can get to Ueno on a single train (in the anime and manga versions, from Keisei Funabashi to Keisei Ueno).” Also, there’s a story that in the Greater East Asia War (World War II from Japan’s perspective), the war orphans all aimed for Ueno together. ○ In the 1957 Little Rock Central High School incident in the United States, the author remembered that President Eisenhower mobilized the National Guard to protect Black students, but when he rechecked at some point, it has become that the Governor of Arkansas, who advocated segregated schools for Black and white students, mobilized the National Guard, and in response President Eisenhower mobilized federal troops.
