New Saga

Plot

The demon king is intent on eliminating the human race at the head of his demon army. The hero, Kail, and his allies attack the demon king's castle and succeed in defeating him, but at what cost? Kail loses all his allies in this war: friends, family, loves, comrades. They are all dead, and he is also dying. As Kail is about to die in one of the demon king's rooms, he notices a strange gem, grabs it, and is suddenly enveloped by a bright light that transports him to the past. Recovering from his initial shock and finding himself in his young body, he decides to become stronger to avoid making the mistakes he made previously.

Characters

Kyle (カイル, Kairu)

As the demonic invasion advanced through the humanoid lands, Kyle lost his homeland, friends and family. In the final battle, he killed the demon king, but at the cost of his friends and loved ones. He then noticed a magical jewel, the Divine Dragon Heart, in the demon king's possession and after touching it, he is suddenly transported to the past. Kyle decides to become a hero so he can have the influence required to help the nations be better prepared for the war. Kyle originally suffered from major depressive disorder before the war, so his sudden change in personality is seen with relief by those close to him.
