The Day I was Born into a Ducal House, I was Branded as a Disqualified Heir, but I'm Still Living Well to This Day!

Although she was reborn into a duke's family, Etowa was born with almost no magical power. Because of this, she was branded with a "disqualified" mark on her forehead! One day, five children are gathered from branch families. They are to serve as Etowa's guards until she turns 15, and the best one among them will become the heir to the duke's family. However, Etowa has an amazing ability given by a god, that she completely forgot about?! A heartwarming fantasy about the strongest kids! (Source: AlphaPolis)
