Don't Mess With Dragon Mom

The mayor's wife and the head of the academy, who is corrupt, spend their time grinding down a poor single mother and her daughter in a remote town. The mother is Seraphina, the supreme dragon archmage who once saved the empire, hiding so that her daughter Aria can have an ordinary childhood. At the Awakening Ceremony Aria's talent breaks out in front of everyone. She is accused of practising dark magic and sentenced to hang. With her daughter's life on it, Seraphina drops the disguise and summons a colossal dragon over the town. She is not hiding any more, and the nobles, the traitors and the bullies are going to pay for what they did to her child.
