HxH: Ryomen... Satoru?

"What happens when The Strongest Sorcerer In History is mixed with The Strongest Sorcerer of the Modern Era?" A cosplayer put on the appearance of his personal interpretation of Satoru Gojo (a version who has consumed 20 of Sukuna’s fingers), but an accident happened and he ended up dying. He then transmigrated and landed in Meteor City from the Hunter x Hunter World along with a not-so-useful system. Afterward, the system assigned him three tasks: 1. Find the Seven Great Treasures. 2. Explore the world of Hunter x Hunter. 3. Max out the compatibility between Satoru Gojo and Sukuna. To complete the first two tasks, he decided to travel the entirety of the Hunter x Hunter world—naturally including the legendary, forbidden Dark Continent. === This is a not-so-weak to strong story, don't expect an overpowered mc at the very start. I don't own anything here, literally.
