Ghibli System in Another World?

(Rewrite from my old Royal Road story that I never finished here: https://www.royalroad.com/fiction/35957/transmigrator-with-the-ghibli-system but since I forgot about that account I'm restarting is slightly different over here. Synopsis Below \/)

Ken waited for an isekai to appear, but he wasn't searching for death either. After he hit his 30's he'd pretty much given up on anything interesting happening in his life. That's where he was wrong.

(This is going to be a complete wish fulfillment story, but I'll also try to limit the OPness of the MC, though I probably wont figure it out either. I had a stroke of motivation so this is where I'm spending it.)
