Raon had lived his entire life as a dog on a leash. However, through a twist of fate, he obtained a new life— even if wrath remained in the wreckage of his destroyed leash. Finally capable of standing on his own feet, he decided to live life by his own will. “I will slay anyone standing in my way… even if it is a god.”
