The Wild Hunt was reborn as a Void Spirit, a cannon fodder among the Void creatures.

In order to evolve, he possessed Kai'Sa in her childhood and became a living skin armor that lived with her. They were twins, and returned alive from the underground world full of Void cancer.

By chance, Corrosion discovered that the skin armor would show different postures on different people and unlock different abilities. From then on, he couldn't stop occupying new bodies.

But the problem is...they all seemed unwilling to let him go.

So let's take them all in!
