Marvel: Reborn Magic

The protagonist is reborn into the MCU with a golden finger system that allows him to extract various skills from anime. This system enables him to acquire powerful abilities, including the "Golden Evolution Technique" from Magic Forbidden Book Catalog, which grants him the power to alter reality according to his mind. With this ability, he aims to prevent anyone from snapping their fingers, a nod to Thanos's infamous act in the MCU.
