I Save the World with Duel Cards

When spiritual gates tore open across Earth a century ago, humanity gained power—but also danger. Chang Wantang was six when the Duel King System chose him, granting him abilities no one else possessed. Now eighteen, he wields his Dark Magician deck like a weapon, summoning legendary cards from Red-Eyes Dark Dragoon to the Sun God's Sphere. Alongside trusted companions, he battles through Spirit Ruins filled with ancient power, climbing toward the apex of strength in a world where every duel could mean salvation or extinction.
