[Western Crossover] Batman Is My Younger Brother

At thirteen, I was away at boarding school and missed the murder of my adoptive parents. At their funeral, I held my little brother Bruce's hand and became his only legal relative.

At eighteen, I started learning from Lucius how to become chairman of Wayne Enterprises. Then I got a call from the head of Bruce's middle school. Apparently, Bruce had heard someone insulting me, gotten into an argument with them, and then ended up in a violent fistfight.

At twenty-three, I read a letter Bruce had left me at a shareholders' meeting, saying he was going to travel the world, and fell silent in the face of a mountain of paperwork.

At twenty-eight, I had just returned from supervising a construction site when I saw a kid named Dick Grayson gazing up at me with irresistible puppy-dog eyes. I fell silent.

"Stop bringing children home."

"I promise this is the last time."

"That's what you said last time."

Tips:

1. The big sister is an ordinary local with no superpowers.

2. Everyone loves big sis.

3. I started writing this to indulge my own preferences.
