A Cancer in All the Worlds? Call Me Supreme Soul Lord!

[Born protagonist + unlimited flow + decisive killing + no heroine (the protagonist's interests come first, killing innocent people indiscriminately, be careful)] In the world of "One Piece", there has been a legend that if you are willing to hand over all your treasures, you can get the blessing of the world's strongest bounty hunter: "KING", and have unparalleled power! So, everyone set out to find [one piece], and the Age of Discovery began. In the world of "Naruto", there is a legend that as long as you are willing to give everything you have, the scientist of the six paths: "Asura" can give you the power to change the world! As a result, the Fourth Ninja War broke out. There is a legend in the "Pokémon" world that as long as you are willing to sacrifice some insignificant Pokémon, the devil trainer: "Nohara Shinnosuke" can let you have a Pokémon! Thus, the biggest melee in the Pokémon world occurred! He is like a cancer, wherever he goes, he will definitely bring blood, war, desire, and endless suffering... Not only in [Dungeon], he is the cancer of the entire Blue Star, and even the entire [Destiny Space]! "What's going on! Isn't his profession a soul master? Why is he so strong!" "Soul Master, no, please call me Supreme Soul Master!" "Also, boy, do you want to gain power?" "If you want, I'll give you everything in exchange!" (The gate of the Soul Palace opens to the south. If you have virtue but no money, don't come~)
