This is a fan article, but not very orthodox.
Because I liked the pairing of KL in "Gundam SEED", I did not hesitate to put the characters into ancient Japan.
Just because I like it...
But, isn't that enough?
As long as you like it, it doesn't matter what anime you are a fan of.
==================================
The snow had just melted, and the frozen river began to flow again. The indigo bird hovered under the sky and then glided away into the distance. Slowly, a blue feather fell. The feathers touched the river water and rippled slightly...
According to legend, that one is the blue bird that can bring happiness and fulfill wishes to the person who gets it.
It is a small island country in the East China Sea, but there are many people who want to take over the entire country. However, it is people like this who split the originally complete country into small countries one after another. No one can win, but they are just fighting a protracted war against Japan. This is probably the origin of the Warring States Period.
So, whoever wins the blue bird wins the world? There are so many people who believe it.
