Yucheng and Yingxue, the oddball duo, were practically the “Undying Pair” of transmigration. After brawling their way through countless worlds, they landed in the dog-eat-dog streets of Yokohama in Bungo Stray Dogs. With itchy hands, they picked up a “little device” and somehow raised it into the cocky Nakahara Chuuya. Once Chuuya joined the Port Mafia, they hid in the shadows as “ace support,” making sure that thing called Arahabaki never came out to cause trouble. He was a kid they had “raised,” after all, so they had to keep an eye on him.
Who knew postwar Yokohama would be such a handful? The “Book” threw a tantrum and kicked them straight into another world. But what was there to fear? They were just as good at playing their way through other worlds! They learned Breathing Style in Demon Slayer. Whatever that Arahabaki energy was, they would suppress it first and ask questions later. In Jujutsu Kaisen, they got their hands on a “Nameless Mirror,” which was perfect for dealing with the “Book’s” curses. In Puella Magi Madoka Magica, they saw the “Law of Cycles” and figured that kind of salvation had nothing to do with them. Then, in The Ancient Magus’ Bride, they learned a trick and simply signed a contract together, hand in hand. From then on, they would share each other’s pain and feelings, making their bond even stronger. In the end, they used the mirror to jump straight back to Yokohama.
By the time they returned, Chuuya had already become an executive in the Port Mafia. They posed as “ghost consultants” to sneak back in, just in time for the “Book” to make a scene. It wanted to sink Yokohama? No way! This time, they joined forces with Chuuya and everyone from the Armed Detective Agency to seal the “Book” inside Chuuya’s “Corruption.” And so the two oddballs’ interworld adventure continues, lively as ever!
A lot of original worldbuilding and a heavily altered timeline. Don’t read if that bothers you. This is purely for fun.
