It was Self-Defence.
"Good."
Saying that, Nux disappeared.
Myrill, who was looking in the direction where Nux was standing with a lost look on his face suddenly felt someone patting his shoulder.
He came out of his reverie when he noticed that Nux had disappeared, he turned around only to see Nux looking at him with a big smile on his face.
"You messed with a wrong person, Pest."
"H-Huh? Wha- Kkhhoookkk!"
Myrill wanted to retort, however, Nux directly punched his gut so hard that his eyes nearly popped out and he directly coughed out blood.
Nux, however, wasn't done.
He grabbed Myrill's hair and then smashed his head on his knee,
"Ugghh!"
Of course, he didn't stop it after doing it once, he lifted Myrill's head, and then smashed it on his knees again, then again, again, and again.
"Ugghh…"
Within a minute, Myrill's somewhat decent face was turned into a disfigured mess that was covered with blood, sweat and tears.
