A star seed in the sky fell into the world with twinkling lights, causing nine of the favored sons of heaven to fall into different corners of the world.
What! You are not my brother! Are you the one? !
What! I came from heaven! The same to you? !
What! I actually have a mission! Are you kidding me? !
"As the youngest star among the nine stars, you are indeed capable of taking on this task, because..."
Because only your mysterious memory can unlock our life experience, and only your extraordinary ability can bring us back to our home planet.
And...
Once the mission fails, you will be alone for the rest of your life.
But... Why don't I remember anything?
