The title, "Flag Z", is my translation of a Japanese phrase, "Z旗". I don't know whether this translation is good, but I'll go on with the story, supposing that it's correct.
The flag consists of four colors and stands for extreme resolutions. Battleship Mikasa, that I wrote about in the last entry, fought the Russian Baltic Fleet with this flag raised and claimed a perfect victory.
This triumph led to the Russians' turning back and made their subject colored people awake to the fact that they're never inferior to white people. It literally changed the white-dominated world that had continued for 500 years. In this way, flag Z became the sign to show strong will in Japan.
