Rowan's reflexes were on a different level. The body of a shackled realm expert couldn't be underestimated. It was clearly on a higher level than a third evolution monster or a person in the solidifying realm.
Souta's sword slash has enough power to damage the tough body of a shackled realm. He saw it clearly, and he tried to avoid it with his maximum speed, which was faster than his sound attacks. Even though he was fast, he realized that the sword slash contained an energy that pulled him towards it.
'It's pulling me?! It's impossible...'
In the end, he couldn't avoid the violent energy torrent from the sword slash. It ripped his left shoulder apart, and his entire left arm flew in the air. It wasn't that awful compared to getting his head cut in two. At the very least, he avoided death.
"It missed..." Doranjan muttered when he saw that Souta failed to kill Rowan.
