How did Joey become a whole body?

Characters are transformed into a complete body through fusion.

According to Tencent's video query, in the anime "The Guardian of Light in GG Bond", the process of the integration of light Joey and dark Joey is that dark Joey absorbs light Joey through the magic circle of energy conversion and becomes a whole. Joey's darkness is different from the original, one side is bright and the other side is dark, similar to the light beast.
