Fans joke that Manaato is responsible for Article 13, as they both put bans on copyrighted media they don't approve of and share 13 as a number.
During the development of Expressive Illumination, Manaato had completely different design that was more based around the original design created by Popcioslav from the old dev team:
Manaato looked smaller in general, almost younger than her final design
Her hair color was darker
Her pink skirt was shorter and her top was slightly different
One of her wings was rainbow colored instead of being painted glass
