Nearly 10,000 years have passed since Bell Cranel's legendary victory over the One-Eyed Black Dragon, marking the end of the Age of Gods as the divine beings returned to Heaven. The Age of Man dawned, leading to humanity's flourishing and the merging of distinct races into one. Bell Cranel, the Hero who heralded the end of the Age of Gods and earned the title of the Last Argonaut, has now reincarnated into the modern world. His original memories have been stripped away, leaving him as Bell Amamiya, still possessing his striking snow-white hair and fiery ruby-red eyes. He resides with his mother, Meteria, a woman of divine beauty, and his aunt, Alfia, who is equally enchanting. Bell, though outwardly human, has undergone rigorous physical combat and weapons training under the guidance of Zald, a close friend of Alfia and Meteria, whom Bell affectionately addresses as Uncle. His exceptional intelligence and analytical prowess were honed by Alfia and Meteria through homeschooling.
