Zero Elea gains the Parallel Memory Skill, accessing memories from his alternate self in a parallel universe. To his shock, he realizes his world is the same novel he once read. A catastrophe lies ahead, but fortunately a main character already works to save the world. This knowledge brings Zero an identity crisis—he recognizes himself as a mere mob character, insignificant and disposable. Caught between realities and wrestling with two identities, Zero confronts an agonizing question: Can he transcend his minor role and become more, or is he fated to remain a forgotten side character?
