Beast Academy: Raising Baby Beasts with Cashback 500\%

After losing her parents as a baby, Shani grew up in an orphanage believing she had no family. At eighteen, a wealthy noble house finally claimed her. Little did she know, the Ashbourne family only wanted the fortune left behind by her parents. As an F-Rank beastman, Shani was destined to die at twenty. Instead of helping her survive, her newfound relatives locked her away and waited for her death. Worst of all, the mysterious Cashback 500% System that had followed her since 5 years old remained silent... until one month before she died. By then, it was already too late. But fate gives Shani a second chance. Reborn on the day her relatives come to claim her, she refuses to return to the Ashbourne Mansion. Instead, she sets her sights on the continent's greatest institution, Grand Novabeast Academy. There, she'll raise powerful Baby Beasts, forge trustworthy Bonds, unlock the true potential of her mysterious System, and rewrite the destiny that once doomed her. This time, she won't be the abandoned girl waiting to die. She'll become the first beastman to surpass the limits of the world itself. — Description from novelcodex.org
