[Western Crossover] A Century-Long Love Letter

In the winter of 1920, Cecilia Wayne, the youngest daughter of the Wayne family, vanished without a trace. The entire Wayne family searched for ten years, but to no avail. Heartbroken, the Waynes left a small stone marker shaped like a baby's cradle among the roses in the back garden. One summer, a hundred years later, a girl in "strange clothes" appeared on the streets of Gotham. Cecilia Wayne, who had been dragged by the System through ten whole worlds, had finally come home! A certain dark knight: "I am the darkness, I am fear, I am..." All right, little auntie, I get it. I'll break those bastards' jaws and come home. It'll be quick. A certain tin man: "I want to get along with Cecilia, preferably as brother and sister... Uh, I guess brother and brother works too, hahahahaha." A certain big-chested sweetheart: "I am a man of yesterday... All right, Cecilia, put down the weapon. I'm not old, I'm not old, so neither are you. Really." A certain Red Hood: "On how I fell for my little aunt, whose distant relative, several generations down, once tried to be my dad." For Jason, Cecilia is a love letter sent to him by the world, crossing a hundred years just to come to him. Please note before reading: 1. Red Hood x heroine, with a touch of raising-the-heroine. The male lead acts like a house dog in front of her but is actually vicious as hell. The heroine has a quirky train of thought and astonishing combat skills. 2. With Cecilia stealing his girl, there's one fewer bird in the Batcave, and one certain unacknowledged, troublesome older relative has... 10,086 more headaches? 3. The heroine bullies Batman on a daily basis. The author is a Batman hater, the kind who hates him more the more they like him. But trust me, they still dote on the guy. 4. The heroine has an overpowered golden finger, and her superhero buddies get carried to victory. The timeline is just a formality, so don't sweat the details.
