Kanon

As the champion of humanity, Kanon is uniquely gifted with seven sources and an unparalleled mastery of source magic, making him the only warrior capable of wielding the holy sword Evansmana. Although he initially stood as Anos's greatest adversary, the two shared a profound mutual desire for peace. Following Anos's ultimate sacrifice to end the war, Kanon realized that the deep-rooted hatred of humans towards demons still lingered. To protect the fragile peace his former enemy built, Kanon willingly let himself be killed by his own kind and orchestrated a two-thousand-year-long grand scheme. By continuously reincarnating and eventually masquerading as the false Demon King, he aimed to bear the brunt of all human hatred alone, thereby breaking the endless cycle of revenge between the two races.
