My Best Bro Turns Out to Be a Magical Girl

Zhou Ying, an upstanding young man and veteran anime otaku, had always kept two secrets to himself.

First: he was secretly a powerful magical girl, like a superhero who was always protecting Earth.

Second: Zhou Ying also had a very cute girlfriend in secret. They had met online, but after three years, Zhou Ying believed their relationship was unbreakable.

Then, on the first day of summer vacation during his freshman year of college, Zhou Ying discovered that his best friend, the guy he'd known since childhood and practically shared a pair of pants with, was also a magical girl. And on top of that, he had an identity that was enough to make Zhou Ying lose it.
