What is Kim's real identity in the concave-convex world?

It is the possibility of rebirth of a fragment of the creator.

The protagonist Jin and his derivative works in the domestic animation "Bump World".

From Deng Lu, a mining planet, this planet suffers from heavy slavery and taxes under the will of God. In order to change the fate of the planet, my sister Qiu took part in the concave-convex contest three years ago and never returned. In order to find her sister and change the fate of her hometown planet, Jin found the path her sister had taken when she grew up and set foot on the journey of the concave-convex contest again.

Role experience;

In order to pursue her missing sister and change the fate of Denglu, she took part in the concave-convex contest. After joining the preliminaries, I explained my little relationship with Grifa and made friends with Zitang and Kelly successively.

At the end of the first season, when the ghost fox drove everyone to a desperate situation, the body suddenly became a form-black gold (commonly known as black gold), which was wrapped in ominous breath and had overwhelming power. Even the ghost fox who absorbed the strength of one hundred people couldn't hurt him.

The attack form is similar to the golden arrow. Everything in this form is a mystery, and Jin himself' seems' to have completely forgotten it, and was later suppressed by the token "square arrow" given by his sister and awakened by his voice.
