His name is Time, the god of time who controls the world. Accidentally signed a time contract with a human girl. He saved the girl's life, but unknowingly dragged her into the abyss.
The girl is like the texture of the pine tree. Every time a new growth ring grows, the girl's life will follow the growth rings and grow into a big tree, and finally end her life.
Intention: Cherish time and cherish the present.
