Summoned Hero

Prologue Since long ago, throughout all of history, the battle between humans and the Demon King is well known. Countless wars have been fought, but the human side always failed in killing the Demon King. They could not even reach the Demon King's castle. Slowly but surely, the human side is getting stronger. It starts when the holy church of Cyndora receives a revelation about a girl that is born with a spirit power level surpassing even the demon lord. The girl taken by the church since birth had grown into a powerful priest. Her only weakness is she could not use battle magic, her magic is limited to healing magic, but it can even regrow severed limbs. One day the girl tries to perform another type of magic. Using ancient rituals, she conducted a powerful summoning spell, "The Hero Summoning". With her massive amounts of spirit power, the ceremony succeeded, and the first Hero was summoned. The first Hero led the human against the Demon King's army, and finally, for the first time in two thousand years, the human military managed to arrive at the demon king castle. With great difficulty, the first battle of the hero and demon king ended in the death of the hero. Thus the priest continued to summon heroes, and one after another, the heroes were slain by the demon king. Thirty heroes were summoned, and 30 battles were fought, costing the lives of millions of humans and demons sacrificed in the fight. The priest didn't stop summoning the heroes because as the time went on, the power of the heroes that she summoned got stronger. The 31st hero was on par with the demon king and managed to cut off one of its horns. While the 30th hero was only able to break through the Demon King's defensive force shield, the rates of improvement are shocking. The 32nd hero managed to injure the Demon King heavily. It was hoped and expected that with the summoning of the 33rd hero would have the power to slay the Demon King. However, the hero summoning can only be done once a year because it consumes a lot of the spiritual power of the priest and needs a lot of time to recover. So the human side waited for the next summoning with joy as they could finally see hope in defeating the Demon King. While the human side was waiting with full of confidence, the Demon King's side had suffered heavy moral damage. The Demon King's army was afraid that maybe, they would meet their end soon. "Father... Are you alright?" A beautiful girl with red eyes and fiery red hair walked to the throne. Her look could charm anyone that laid their eyes upon her. A body with perfect curves and black wings growing on her back, she was without a doubt a demon. Moreover, the tiara on her head shows her status as the Demon King's daughter. "Rosalie… I'm fine…." The Demon King, as her father, had a manly look. With only one horn remaining, he looked like a war god that had survived countless life and death situations. Right now, he sat on his throne with one hand on his head. "I'm worried, father... The power of the humans keeps growing... Each time you defeat a hero, another one appears with greater strength... The last one even managed to cut off one of your horns." A demon's power can be seen by the size of its horn. Horns are not just a decoration. They also serve as power storage. Therefore the stronger the demon, the bigger the horn. With one horn remaining, the Demon King could be said to have only half his power left. "I know Rosalie... I don't even know how they get stronger every time. The human in the Magora Continent don't have much power, yet they keep on coming with unbelievable strength." "Father... I heard that these humans are summoned through an ancient ritual. It is called "The Hero Summoning" if I'm not mistaken." The demon king frowned and fell deep in his thought... "Ancient ritual... Hmph... Hero summoning... Hmph... If they're summoned from another world, that explains their strength... No human in this world can match my power... Hmmm.. " "Father... If the humans can do this 'Hero Summoning', can't we do it too?..." The Demon King looked at his daughter with a surprised look and grinned. His smile was so grim it could make countless children cry and cower in fear. "Rosalie! You're a genius... I never heard of it before, but it is possible. Thank you, Rosalie." He stood up from his throne and gave orders to his guard. "Quick, call Vahjra the blood mage here!" Instantly his guard nods, make a salute, and runs out of the throne hall, and disappear into the shadows. "Hahahahahaha... If the human can summon a hero, why don't I summon a hero by my side? Hahahahahaha..." Rosalie wasn't sure of what had just happened, but she's was happy seeing her father was no longer gloomy and depressed. Soon, the tides of battle shall change... The first hero will be summoned to the Demon King's side...
