My name is Alexander. This might sound crazy, but I wanted to let you know how I died. That day, Panhumanity Alliance launched an ambush on the demon king's castle. We were colluding with our friendly dragon and infiltrating the demon territory from a high altitude. A few heroes, including m,e and a few elites of each race, were forming a team to infiltrate the demon king's castle. We aimed to gang up on the demon king when he was by himself. It sounds like there was no problem with this plan, but it was ultimately an assassination plan. Moreover, whether this plan was a success or a failure, the whole team had literally zero hope of returning alive. The reason why we had to rely on this tactic showed just how much the Panhuman alliance had been cornered. Though we were travelling so high in the sky to the point that someone might freeze to death, we weren't intercepted, and the entire team managed to infiltrate the castle safely. The battle in the demon king's castle was severe. Though the demon race was flustered at first when a group of heroes suddenly descended from the sky, they quickly got a grip on themself and started the counterattack. Archdemon(Top Brass of Demon Race, Vampire Lord whose strength is rivalling the progenitor vampire, Lich, who hides an enormous amount of mana, and countless royal guards of the demon race I didn't even want to remember the battle of that day. A few heroes and my other comrades fell amid those chaotic battles. Nevertheless, I don't know if it was because we were lucky or not, but we managed to reach the demon king's place. The haughty king of the Demon Race. He even greeted us upon our arrival in the throne room. Different from humans, for the demon race, strength was everything. In short, the demon king was the strongest combat mage of the demon race. Our assault team's exhaustion aside, that fella was simply way too powerful. Not bad, heroes. The demon king spoke nonchalantly as he gripped who was already on the verge of death-by my neck. Overwhelming physical strength. A gargantuan amount of mana that cancelled all kinds of magic intervention. Which combined with the heretic art which he learned from a contract with the devilSoul Eater. The demon king became stronger every time my comrades died. As a result, more and more of my comrades had died. The battle turned into a nightmarish slaughter. You did a good job for a weak human. Damn it. You can speak even in that state, eh? He put more strength into the hand that was gripping my neck. And just like that, I was choked to death as he crushed my neck. Your soul is delicious. It's a good supplement for us. The demon king's dark mana entered my broken neck. I, who had exhausted my mana and physical strength, had no strength left to resist. GU GAAAAAAAAAAAAAAAAAAAAAA!!! And exploded like an overloaded balloon. Yes, my body was EXPLODED into pieces. My consciousness descended into the darkness along with the resounding laugh of the demon king. At that moment, I thought that I had already died. But. But then, the hateful face of that demon king was right before me by the time I woke up. Uhm, he has such a fearless look on his face despite being a baby. ABUA!?ABABUBUBAA!?(DEMON KING!? WHAT IN THE WORLD IS HE DOING IN THIS PLACE!?) I shouted, but it wasn't words that came out of my mouth. My body feels strange. What's happening here? It seems I was held in someone's hands. I mean, just how big was the fella who could hold a tall man like me No, it seems I was wrong. I was the one who became smaller. The colour of my skin was blue. And yet, my arms were squishy. ABABUAAAN!?NO WAY, A BABY!? I became a baby. And a demon race's baby on top of that. He's such a lively boy. Uhm. Well, nothing wrong with having too many heirs. Your Majesty, if possible, please give this boy. Jilbagias. The demon king left the room as soon as he said that. Honestly, I was dumbfounded. You must be kidding me. Is that a father's attitude toward his newborn son? But then, the woman who held me revealed an eerie smile as if she didn't care about the demon king's attitude just now. Finally, ly gave birth to a child too. And then, the next thing that I saw was the cold beauty of the demon race. Oioioi, are you telling me that this crazy-looking beauty was my mother? The thing that oozed out from her eyes wasn't the affection of a mother for her,n it was deep-seated emotions such as stubbornness, ambition, hatred, and many others. Jilbagias. And this woman called my new name with her creepy voice. You will become a demon king. And showing a smile that sent a chill running down my spine. You'll get rid of those annoying old hags' brats, right? fufufu HAHAHAHAHAHAHA! In this way, Hero Alexander was dead. And then, reborn. As the demon kingdom's prince, Jilbagias.
