So you like this but not the title?
Then why would the title matter in that case? I could name a book "Eating booty like a Wookie" but if it contained the cure for cancer, you wouldn't give a shit about the title right?
Plus, he's literally the only one in the world with this system. The title is pretty much directly summarizing the premise of the story. It's like naming an isekai story about a hero defeating a demon lord, "Hero defeats demon lord in another world." Now if any other story has "hero", "demon lord" or "another world" in the title, it's copying this one? See the problem with that?
