His name is Bryce, a man who lost to the demons in the past. 500 years ago, Bryce and his wife challenged the demon king in a battle. Losing the battle and the love of his life, Bryce was rendered immortal by the demon king. He has no chance of winning and has no purpose in life. Now, he is a pathetic demon hunter. Although there is no need for him to eat, he hunts weaker demons to earn small change for his daily drinks. He is immortal but not invincible! Let the enemy cut your flesh to strike back with a greater blow. Death is nonexistent and there are no rules. The battle of the immortal hero, Bryce, begins now.
