(Naruto-Centric Crossover) The Consequences of Shipping the Wrong Couple

[Updates are slow. Please whip me along with your love?] Because they like each other, because they love each other, they are together. No obstacle can break their resolve or their instinctive desire to draw close and lean on one another. But what if, this time, the thing standing in their way is an entire world? World: Get the hell out of here! I'm not taking the blame for this! Every time Senju Tobirama and Uchiha Madara fall in love, they end up back in their younger selves, with all their memories gone. Their memories return when they meet again at the Nanga River, starting the cycle over. At first, they work hard to build a better world, stay positive, protect their brothers, resolve disputes and hatred, and join hands to create a harmonious (loving) Konoha (nest) (den). Every day is filled with love and peace (not really). Over and over again. Even the gods are ready to throw in the towel, let alone mere mortals. So, in order to break this endless cycle of reincarnation, Senju Tobirama and Uchiha Madara make a deal with the god of death in this world. They travel to various worlds and seek the approval of each world's pillars for their relationship. In doing so, they can make a contract and use the power of other worlds to permanently shut down the passage interfering with their own. Transmigrators from other worlds: Is that seriously your excuse for breaking up my CP?! I'm not eating your dog food! Take it away! Tobirama: I think... Madara: We've found the culprit behind our situation. They both draw their kunai. Transmigrator (shaking with fear): ...Is thinking about it a crime now?!
