Simultaneous Transmigration: We Share a Role-Playing System

After a clichéd time-travel story, Locke transmigrates, becoming one of many different beings. Unfortunately, due to their orphan status, they are constantly targeted for no apparent reason, frequently finding themselves in danger. Amidst life-or-death crises, Locke and his companions finally meet, and to their astonishment, they discover that besides sharing abilities, they can also share a system: the [Strongest Role-Playing System]. They can exploit system bugs to simultaneously play different characters from various realms, becoming a force to be reckoned with. In The Boys, Locke, persecuted by superheroes, returns from hell as a hungry wolf hunting heroes. In Jujutsu Kaisen, Locke, now a spirit possessed, transforms into the ancient swordsman Nishikita Kojuro Keiryu, rekindling his romance with Sukuna Oni. In Naruto, a war orphan from the Nara clan obtains the Ten Kage Technique, constantly adapting until he becomes the strongest being. In the DC Absolute Universe, a Space Marine undergoing 22 modifications appears; in the One Piece world, a fruit-selling martial artist emerges; in the Demon Slayer Corps, a new Pillar named Sasuke becomes Muzan's inescapable nightmare; in Infinite Terror, the Shadow King's army-style fighting style shocks the Central Continent Team. With more and more Locke joining, characters from all realms are now invading!
