A moment later.
The ghostly figure seemed to have exhausted too much energy. The black smoke covering its body gradually dispersed, and it slowly drifted toward the ground from high above like a leaf. Along the way, its limbs occasionally twitched, as if struggling unwillingly, yet powerless to do anything.
The battle ended far sooner than Reilo had expected.
However, this was not entirely beyond his expectations.
