"It Seems the Strongest Demon King Has Been Reincarnated as a Girl in Modern Times"

The Demon King had grown tired of living. Having been killed through scheming, he decided to use a transmigration technique to be reborn. He was reborn in modern-day Japan in a certain dimension. He was reborn as the granddaughter of the leader of the Reizumi-gumi, a directly affiliated faction of the Asura Blade King Society, the largest violent organization in the Kansai region. Originally aiming to become a frail beautiful girl, he lived life with restraint.
