[D.Gray-man] The Brother-Obsessed God of Death and the Sprout Angel

Allen Walker has a Komui-level sister complex, though they share neither parent. She is a stunning beauty with fair skin, a gorgeous figure, and long legs, but her personality is as foul as a street punk's. The two of them show off their affection without even realizing it, and everyone in the Black Order knows they're secretly in love with each other. But they both insist their feelings are nothing but pure familial affection. Amy: "Allen is adorable, and he's so good to everyone. He's broad-minded, kind, and gentle, and his occasional scheming side is so charming. His terrible sense of direction and bottomless appetite are adorable too, and when he smiles, he looks just like an angel descended from heaven. But we've been siblings since we were little! How could I possibly have such improper thoughts about him? Besides, how could a tomboy like me ever be good enough for Allen?" Allen: "Huh? Amy and I are just family. Amy is beautiful, strong, and so cool. There's no way she'd like me." Everyone else: ... In short, it's the Black Order version of Kimi ni Todoke. An Allen pairing fic. Two years apart, with no blood relation, they're not actually siblings. Lots of headcanons. I'm familiar with the story up to manga chapter 239, and I'm waiting to be proven wrong.
