This is a book that includes Ado characters. This is a self insert book of my OC that takes inspiration from Ado and her outfits, it's more related to magical school topics, education and somewhat like Madoka Magica.
Here, this is a world with Goddesses from many years ago. Soon they started to pass down their powers to the girls in this particular school. Ado, is the first descendant of The Universal Goddess, the goddess who overpowers every other goddess. However she wanted to live a life as a normal God, so she created a young girl with the majority of her power, and that girl slowly trained herself for many years to come close to surpassing the power of the Goddess who created her. This means that she surpasses the Goddess of Harmony, along with many others.
