The explosion had blown Thirteen off from Blacky's back, making the boy wince in pain.
He could feel the searing heat in his surroundings, and he knew that Arundel was just dozens of meters away from him.
"Who did you call a coward, boy?"
The Majin Prince walked toward the fallen boy's direction with a devilish smile on his face.
"My Old Man," Thirteen replied, as he propped himself up from the ground. "I called my Old Man a coward."
Arundel sneered. "Is that so? Well, time for you to die then."
The Majin Prince then pointed his finger at the seven year old and unleashed a fireball that was the size of a car.
He might look calm on the surface, but Thirteen's words affected him, especially the part where the child talked about how groveled and begged one of the Celestials to spare his life.
