Takemichi's Twin Sister (Tokyo Revengers x Female Reader)

What if Takemichi Hanagaki has a twin sister from a different father? It's impossible right? But there's actually a phenomena that twins can have different fathers, this phenomena is called heteropaternal twins.

Takemichi's Mom cheated on Takemichi's Father because his mom was tired of getting abused again and again by his father, that's when his mom met our OC's dad, Azrael.

Azrael here, is actually a son of a mafia leader, that makes our OC a mafia princess, but what's more surprising is our OC had the ability to see the future.

How will our OC help her brother Takemichi in his mission? Will she be able to save everyone from dying?
