I Prefer Becoming a Little Sister to Being One of the Guys?

As the legendary boss of the Kansai yakuza, I somehow got reborn as the delinquent little sister who ran away from home in my previous life?

I was planning to be a shut-in and spend the rest of my days watching Yosuga no Sora. Who knew the original owner of this body was in love with my old nemesis, Kimura Yuto?

And my hopeless brother is an ultimate siscon with no blind spots, twenty-four hours a day!?

I thought this was already a hellish start, until that old nemesis leaned close to my ear and casually murmured:

"Actually, I'm reborn too."

"You? Reborn?" I stared at him, dumbfounded. "Then who the hell am I?"

"You're just a troubled girl who needs to be saved."

"???"
