In the midst of a rain of blood, a devil laughed while holding Zeth's lifeless mother in his arms. "You're weak, mortal! Powerless! Hahahaha!" The devil laughed. Tears still streamed down Zeth's eyes as he stared emptily at his mother in his arms, or rather her lifeless body.
Something inside Zeth felt like it was suffocating him. It tightened his heart. He felt a burning fire in his stomach and his lungs seemed filled with ashes. "Because of me," thought Zeth. He attributed these events to his own weakness. What had he lived for all this time? What was the meaning of years of training if he couldn't even protect those in front of his eyes? These thoughts filled Zeth's mind as anger slowly engulfed him.
There were red sparks around Zeth. Taking deep breaths, Zeth slowly raised his head and looked at the devil. Zeth's irises were filled with blood, and vapor emanated from his body. The same pressure Zeth had felt half an hour ago was now affecting the devil. The devil looked at Zeth with a serious expression, but what he was trying to see was not Zeth himself, but what was inside Zeth.
"Mell?" said the devil.
"Mell!" The devil suddenly tensed up and took a few steps back.
Zeth, who could only produce wild growls and had strange things on his body, gently placed his mother's lifeless body on the ground and stood up. After a moment of eye contact with the devil, Zeth appeared in front of him with incredible speed and plunged his arm into the devil's abdomen. The devil screamed in pain, then delivered a strong punch to Zeth, sending him tumbling on the ground. Slowly healing himself, the devil looked down at where Zeth was. Zeth had stood up and was healing all of his wounds as well.
"Sooner or later, you'll be too weak to save anyone, Mell! Just like you were when you attacked our father alongside that weak human! You're destined to lose here too! You're doomed to fail, Mell!" the devil shouted. When Zeth struck the ground with his superhuman strength, the devil was propelled into the air. Zeth teleported in front of the devil and stared at him with a terrifying, yet expressionless gaze.
"YOU WILL FEEL THE POWER OF THIS WEAK HUMAN INSIDE OF YOU." Zeth said.
With all his might, Zeth punched the devil in the face. It was such a powerful punch that not only the devil's head, but his entire upper body and the ground beneath his feet turned into dust. A tremendous shockwave spread around, and along with the shockwave, Zeth was propelled into the air.
Zeth's consciousness faded away.
