[Western Crossover] The Sister-Con Saves the World

[Premium release on July 4, 2018. Three updates combined into one, thanks for your support~] [Note: Halfway through writing this, I suddenly got word from above that Marvel stories weren’t allowed. To avoid trouble, I ended the story early, so I don’t recommend buying the full version.] Tell me, do you want a big brother who’s obsessed with his little sister to the extreme, grows from an adorable young boy into a handsome young man, and stays a ridiculously charming silver fox even when he’s old? The Black Mud System welcomes you! It’ll bind you to a big brother who dotes on you for life. He’ll never betray you, fall for someone else, or choose a sister-in-law over you! Black Mud: always a quality product! ...Shafar believed it. And so... Loki: “My twin sister died in my arms...” Magneto: “My sister was dissected in front of me as a research subject...” Snape: “...I lost my light forever.” Hannibal: “I’ll never forget what happened to Mischa...” Many years later, Iron Man looks at his sister, whose secret identity has been exposed, in despair. “Can’t you just stay alive???” Shafar: ...Sorry, but Black Mud is just so delicious. I really can’t help myself _(:з"∠)_ Important notes: A prominent warning from the Black Mud author: please pay attention to the story’s genre tags. The female lead has a special identity. Some of the brothers are blood relatives and some aren’t, but they only have familial relationships with her. The female lead is sweet on the outside and dark underneath, with a masochistic body and a sadistic heart. She has no points in romance, so please take note. Major OOC. The female lead is mine; everyone else belongs to the original works. No baseless negative comments! Theme:
