My Best Friend is the Hero

After getting betrayed and killed by someone he holds dear. Max finds himself thrown into another world as a baby. Born as the first son of one of the supreme general and first general of demon army. Max (Arcon) has to strive to reach the expectations of the society.
As though the world wants to mock him, when his powers are checked, not only does he have only an ego, which falls short as a primal demon, his only ability is luck. Through the encouragement of his ever-loving mother, he pulls himself together and trains to live a decent and quiet life and not disappoint them any further.
To pour spit on the wound, one of the most prodigious demons named Crystal Del Monre takes deep interest in him after hearing a prophecy. He tries his best to avoid her eyes and the attention that it brings but all to no avail. Through her tortures...err...help, training and tutelage, he manages to advance to higher levels of strength, but such training brings about problem, a problem to his essence. His essence now tainted with chaos aims to drive him to and past his breaking point through unending nightmares.
After ending the hero and his group and subduing the human army, the demon continent is plunged into chaos by an organisation whose end goal is to put demon back on their 'right path', the path of never destruction and carnage. This event leads to Arcon's most fruitious encounters. During a dungeon raiding as per usual with Crystal, he stumbles into a missing room with an enchanted book at its centre. Feeling compelled, he walked closer, hands outstretched towards the book. He had finally reached it, all the conditions clear, the space and state to complete his missing part. Chaos was complete, his mind serene, his purpose, his goal clear. Rain down destruction and chaos to the world. Engrave their hearts with fear at the utterance of his name. Who was going to stop him? The monster in him finally unleashed. What hero could slay his predatorial hunger? The time for demons to rule drawing ever closer. The fate of all other races dangling on a thread. A force on like any other, only another of greater intensity could bring an end to it. Who might it be? Where might they be? Only time will tell.
