You know, waking up in another world was very mind-blowing to Ken. But what's more mind-blowing is that card games were the main bread winner method of making money. He got isekai-ed into Yu-Gi-Oh. That's really cool, working and getting fat stacks by playing a children's card game. There was just one slight problem. He wasn't a pro in the real world or anything. He was just a rogue deck Platinum player that hit his peak in Plat 4 on Master Duel just a month ago. Haha... He's so dead.
