Nan-shu

Nan-shu is the deuteragonist of Chu-Teng. He is a Star Light that serves as the Guard of Chu-Teng. After separating his head from his body and going into Ge-Teng to stop the darkness from taking over Chu-Teng, he was attacked by Chui-hei. This attack caused the parts of Nan-shu's face to be scattered across outer space and the Earth. Nan-shu transformed the two parts of his face that fell to Earth into different items to help Rin in his mission. His ears became the Chu-Teng Tablet and his left eye became a ship for Rin to travel across Chu-Teng in.

Chu-Teng Tablet: "The Voice of Nan-shu"

The Guard of Chu-Teng
was I, Nan-shu.
I removed my face from my body
in an effort to survive in Ge-Teng.
I left behind my body in a room of the Star Palace
and proceeded towards Ge-Teng.
I was not a light of the Star Palace
from the very start;
I did not belong to any palace at all.
However, Suin-shin
adopted me as one of his own.

I had to put a stop to the darkness of Ge-Teng
both for the sake of Suin-shin
and for the sake of the lights of Chu-Teng.
However,
by absorbing the chaos and conflict in Chu-Teng,
the Supreme Darkness in Ge-Teng
was swelling into a giant force of darkness and growing in power.
A blow from Chui-hei struck me down.
My face fell apart
and was scattered throughout
Chu-Teng, Ge-Teng, and the Earth.
