Have you heard of such a legend? In this world, there is a kind of blue bird, facing the beautiful sky, it has no power to see. It is the saddest blue bird, but it always flies so high.
Loneliness, sadness.
The blue bird is a lone messenger, but that does not mean it will always walk alone.
There is a race called the Light-Darkers. They cannot see the sky, birds, or colors. The incarnation of the One of Light and Darkness is the blue bird of Ren, so they, like the blue bird, are destined to be alone.
Bluebirds will pass by many scenery, they may be nostalgic, but they will not stay. -----It is said in fairy tales.
----------------------- So this time, please commemorate the blue bird's journey that is no longer alone.
