Restart The Weakened Hero

Saki was reincarnated into another world, and flourished in the ultimate role of being the hero! She had been thoroughly enjoying her new life rescuing people in trouble and defeating evil dragons, all while adventuring with a fantasy harem she created. But right when the Demon King became the only remaining enemy, Saki received a letter stating "the balance of the hero role is being readjusted." In other words... the abilities of the hero were weakened, causing everyone to start calling the hero "the job that God gave up on." The weakened Saki is now made fun of by those of all other professions, and loses to the monsters she took down so easily before. But Saki continues on as the hero, no matter how much she's made fun of or looked down upon... Thus begins the adventure of aiming to become a true hero! Source: Shogakukan
