Part-Time Superhero (SaTzu)
20 parts Complete Tzuyu is living two lives. She is a boring teenage student as well as a prestigious superhero. Sana's encounter with said hero has made both of their lives a whole lot more interesting.
Tzuyu is just your average teenage girl; she picks her nose, stresses about school, and messes around with her friends. She does, however, spend her free time a little differently. Instead of going shopping with her friends and gossiping about boys, she saves people in her spare time.
Sana, a new resident in the city, had originally thought that her life was relatively boring. It wasn't until a certain encounter with a special superhero that she realized that she would be experiencing a very exciting life.
Note: This story used to be on my Asianfanfics account (MagicalBeans), so if it looks familiar to you, that's probably why. Also, I've written this about 5 years ago and I can't even bring myself to re-read the whole thing because I'm cringing.
