What Do I Do If My Brother Is a Transcendent?

[Sorry, I’m stuck on this chapter. The bonus side stories may update slowly. Apologies!!!] I transmigrated. The good news: I landed in Bungo Stray Dogs, very early in the timeline, with plenty of room to maneuver. The bad news: I’m in Germany, fresh off a smuggling boat, with no known identity and no legal status. The good news: A kind couple adopted me. My adoptive parents are well-off middle-class, and I have friendly older siblings, too. The bad news: My brother went off to war and disappeared, while my sister married far away. I haven’t seen her in years. Many years later, I went to college. My parents and I stopped talking about my missing brother. Then one day, a guest who seemed strangely familiar came to our house. “His name is Faust,” Mom said. “He’s the new neighbor.” I studied his face. The longer I looked, the more familiar it seemed. Memories from over a decade ago surfaced, and I recalled the gentle big brother who had patiently taught me German. His face gradually overlapped with my brother’s... Just as I was about to confront him, a red-clad shadow suddenly appeared behind him. It put an index finger to its lips and made a shushing gesture. At that moment, I heard the devil whisper... The devil clung to Faust’s ear, staring straight at me as it murmured, “I want to play a game with him. What do you think, Faust?” Faust’s expression didn’t change. He didn’t even move his lips as he said coldly, “Don’t touch my little brother.” P.S. Faust is the older brother. There’s a reason he changed his name. The brother is based on Goethe, and his ability is [Faust]. He and the protagonist are not blood-related. I started writing this because I’m bad at writing romance and wanted to practice, so the protagonist may fall in love more than once, possibly with most of the original characters you know. The main story has an open ending, with different endings in the side stories. Not every pairing is guaranteed its own ending. There is a secondary pairing, Ranpo and Poe, or Poe and Ranpo. They mainly serve to advance the plot and appear in no more than three chapters. I can’t guarantee every detail will be accurate, so please don’t nitpick. If you don’t like it, please leave using the back button. Don’t give me writing advice. If you think my writing is bad or some parts are unnecessary, please stop reading. Neither of us will enjoy this. This story was originally meant to be locked behind a paid-completion status, but because of a Jinjiang profile picture event, I chose to reverse-lock it while it was still being serialized at 170,000 words. In fact, it’s already not far from the ending. I won’t delete comments, but I can’t promise I won’t bury any of them. The anti-piracy ratio is the minimum, 30%. The main story is told in third person. Theme: Spread truth, kindness, and beauty.
