Cross-World Arena: Battle for the Summit

When the pinnacles of every world are brought together on a single stage, who truly stands at the top? A gigantic screen descended from the sky. Four worlds were selected, and sixteen powerful fighters had their fates decided by lottery. The streets of Morioh, the Shibuya Scramble Crossing, the bamboo groves of the Warring States period, the waters of the New World: the people who stood at the peaks of their respective worlds were drawn by a beam of light into the same battlefield. No one can truly die here, but the pain is real. The results are recorded only on the scoreboard, but every duel stakes the pride of one world against another. There was an ordinary man, unqualified to compete, who could only watch from the stands as monsters tore into each other in the arena. He fell into this world and couldn't go back. From then on, he was no longer just a spectator. He began recording every fighter's habits, analyzing the flaws in every battle, and writing the strong ones' weaknesses in his notebook, one by one. His name quietly spread from one division to another. No one had ever seen him, but everyone used his intel. While those arrogant powerhouses stood at the summit and looked down on all creation, this powerless mortal was climbing the same mountain, step by step, in his own way. -- Even a mortal's eyes can see the summit.
