[Bungo Stray Dogs] A Duet of the Ordinary and the Extraordinary

Five-year-old Yuan Erya accidentally crossed the dimensional barrier and found the newly born Arahabaki and a human-shaped mass of darkness who had run away from home. The older brothers were so pitiful! So she brought them back to Huaxia. In the Bungo Stray Dogs world: Where are our Double Black duo?! How is this plot supposed to go?! At eighteen, Yuan Erya returned to Yokohama, Japan, to find relatives for her two older brothers. Then she stared pensively at the strange five-story building. This isn't like the travel guide. The eighteen-year-old Port Mafia executive Dazai Osamu announced, "I'm going to kill myself right off the bat." Yuan Erya took out her phone. "Mom, Brother Dazai is playing his suicide game again." Yuan Mom: "Enough talk. Bring out the washboard." The eighteen-year-old Port Mafia executive Nakahara Chuuya kicked a crowd of enemies in one go. Yuan Erya took out her phone. "Dad, Brother Chuya's getting into fights again." Yuan Dad: "That little brat. I'll deal with him when he gets back." As it turned out, no matter how ruthless Double Black was, they were no match for the parents of Huaxia. Freshmen in criminal psychology, Yuan Dazai and Yuan Chuya, cried, "We're innocent!" Then the Huaxia duo fighting crime ran into the Port Mafia's criminal duo, Double Black. Their worldviews shattered. All four of them: "This can't be me!!!!" OOC warning: Extremely out of character. Just a silly story I wrote for fun. Mostly family bonds. The characters are overpowered, but there might not be any romance at all. Theme: Silly fun
