Gin: Collision

The main character is Gin, both of them. When Gin, who had experienced the demise of his organization, changed his name and became Kurosawa Formation, he got a small system. When Xiao System took Kurosawa Formation to another world of Conan, he met Gin before the organization was destroyed. When Kurosawa was about to start his plan, he suddenly discovered that the world was like a sieve, leaking air everywhere, and things like vampires and demon kings ran out! In desperation, Kurosawa Formation can only patch up the world, at least on the surface, it can be seen through. Detective Conan, Twilight Saga, HP World, so many for now
