[Western Crossover] If B Had an Older Sister Who Transmigrated

Helen was poor in her last life.

So when she learned she had been reborn as a young lady of the Wayne family, she started drooling and racking her brains over how to hold on to this hard-won life of luxury.

First, get Mom and Dad to buy a massive life insurance policy?

Bruce Wayne has an older sister.

Since childhood, she has kept him at the bottom of the food chain, ruined his long-awaited movie nights, and forced him to learn how to manage the family business and handle social niceties, while she lay nearby enjoying their parents' attentive affection.

As she grew up, she only got worse. She would disappear all night, fill the tabloids with scandals, and become obsessed with extreme sports, suffering a broken arm, a broken leg, or a concussion every few days. The Wayne parents retired early and left Bruce to take over the family business, while he also had to keep cleaning up after his sister.

Bruce Wayne couldn't understand his strange sister.

...Until one day.

He met himself from a parallel world.
