Surviving Everywhere in a Monster's Secret Identity

Hey~ brave young one, would you make a pact with me and travel through all kinds of worlds under different identities? It's okay if you don't want to~ Jiukuisheng, an ordinary boy from Yokohama, is facing the greatest crisis of his life. He goes out in the middle of the night to buy toilet paper and accidentally stumbles into the scene of a gang fight. One of the gangs, following the principle of never letting anyone get away, hunts him down relentlessly. Just as he runs into a dead-end alley, a mysterious System requests to bind itself to him. "What if I don't want to?" Jiukuisheng asks cautiously. "Since the existence of this System must remain an absolute secret, this System will speed up the deaths of anyone who knows about it~" You're something else! And so, Yokohama comes to see: The goldfish princess who follows the gods The little mountain rabbit sprinting through the night The sakura princess dancing gracefully The mysterious fire with sparks filling the sky The shy, reserved little firefly grass (More will be added later. Taisho and Tokyo will depend on how things go.) Theme: Life always brings plenty of difficulties, but you must never give up on hope.
