Kim and Greer are official partners because they are very close in many scenes. In the first season, the center suddenly fell from a height, and Greer suddenly came forward to hug a princess. Also, when Gadros and Greer were fighting, Gadros saw Kim and became interested in him.
Greer directly raised and slashed the gold behind him, which surprised Caderousse. Presumably, Jin and Greer have a deep sense of cp, and there is also a combination called Ruijin cp among scholars.
Kim's introduction:
Jin, the protagonist of the domestic animation "Bump World", seems to be a cheerful and sunny teenager. From the beginning of the mining planet Dengru, this planet bears heavy hard labor and taxes under the will of God.
In order to change the fate of the planet, Kim's sister Qiu participated in the concave-convex contest three years ago, but never returned. In order to find her sister and change the fate of her hometown planet, Kim once again embarked on the journey of the concave-convex contest when she grew up.
At the end of the first season, when the ghost fox drove everyone to a desperate situation (the bottom line of the main step on gold+the situation was forced), gold suddenly became a blackened form, and an ominous breath wrapped around him, an overwhelming force. 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 about this form is a mystery, and Kim himself seems to have no memory at all. Later, it was suppressed by the badge token "square arrow" given by my sister and awakened by the sound.
