Kazuya got summoned to another world where he becomes the chosen hero to defeat the Demon Lord. Although many things about him were rare even for a summoned hero (his patron deity is unknown, his starting level was LV 1), he still became the hero for the Kingdom of Melia through sheer charisma and willpower alone. With his party, he sets out on his journey. However, misfortune befalls him and his party and Kazuya saw his entire world fall apart. Now branded a fallen hero and a traitor and a heretical servant of a dark god, Kazuya becomes a recluse. But when a priestess on a journey to bring back a forgotten god asks for his help, Kazuya was given a second chance to become the hero he was meant to be. His redemption story begins, starting at Level 1.
