August Clementine was once Reacher, a wealthy and thrill-seeking businessman who had everything but satisfaction in life. After a fatal adventure, Reacher awakens on a parallel Earth, in the body of the destitute and troubled 19-year-old August Clementine. With his new identity, August finds himself burdened with debt and responsible for his beloved younger sister, Sophia. Desperate to change their fate, August immerses himself in Enders Light, a cutting-edge VRMMORPG that blurs the line between virtual and reality. In this fantastical game world, players can bring specific items that meet certain requirements into the real world and even gain a fraction of their in-game abilities and strength. Stuck at level 12 and unable to progress past his starting village due to a rare armor shortage, August must rely on his wits and determination. A breakthrough comes when he retrieves a mystical purification stone from a river teeming with magical aqua beasts and uses it to cleanse an ancient, corrupted altar. His reward includes the legendary Fruit of Corruption, a priceless item with the potential to grant supernatural abilities in the real world. Caught between the allure of selling the fruit for financial security and the temptation of gaining extraordinary powers, August must make a choice that will define his and Sophia’s future... “What? I gained the ability to extract any item from the game into the real world without restrictions?”
