I use Yugioh to battle the multiverse

A story about a young man named Katsu who received the Yughioh system Now he enjoys life in his own way with his loved ones and spirits. Yes this is a harem I will upload anytime I like (usually in a week) if I am not uploading then I am thinking of ideas or I am busy. And I am not a Yughioh die hard fan but I still love the anime. My grammar is not good but I still want to try and If you don’t like it go. My stories is original and Mc, but not the characters I am going to use maybe some are.
