Hint: Take a look at the description of the story

As I started wondering what God could possibly be willing to give someone like me, and what he’d want in return… he flicked me on the forehead “I literally just told you to stop overthinking things, if you really want to know why I would offer you something, it’s because I’m bored as hell!” I looked at him incredulously as he continued his rant “I mean do you see anything to do around here? I have to create and go to different worlds to have my fun, but even THAT got boring eventually. So you know what? Maybe I don’t need to be the one having fun, let’s see how you do. You wanted to go to the world of demon slayer? Hope you didn’t pack your bags because you can’t bring them with you” God stopped to take a breath, and taking his advice and definitely NOT thinking about how and why an omnipotent being would need to breathe, I finally realised what he was talking about “Wait you’re sending me to the world of demon slayer?” I said, fully expecting to get laughed at again and told that of course I wasn’t being Isekai’d into my favourite manga. Instead he started clapping “Wow good job, he finally gets it! Yes I’m sending you there because I’m bore-” Whatever he was about to say was interrupted by me cheering. My wildest dreams were about to come true! I couldn’t believe it, I was so happy! “Oh and before I forget” God starts speaking again so I momentarily put my one-person party on hold “There’s a few small changes that I made to the world. Namely, I changed the ages of the characters to be around your age… Wait how old are you again?” God asked, I was about to return his question with a question of my own about why an omniscient god doesn’t know something but decide it’s best just to answer him “I’m 22… wait if you already changed their ages then how did you not know?” I can’t resist adding yet another question “Also why did you change their ages?” God looks at me and responds “I know what you’re gonna be up to down there, I can read minds remember? Wait… don’t tell me you’re a lolicon?!” He says before covering his arms over his chest protectively. I struggle to stutter a response before he starts laughing again “Jeez, loosen up will you? I’m joking. Anyway I’m getting really bored of this conversation so I’ll send you on your way now” God says before snapping his fingers “Wait I have so many questions!” I yell to… nobody. What a dick.
