And in that Diagon Alley, a boy grasped his first magic wand...

The girl, who had endured many hardships, became a member of the navy, and sang her own song of justice.

Smoker: As a student of Professor Zeff in the same year, I am ashamed of myself. Am I the mad dog or is she the mad dog?

Akainu: I greatly admire Erza's sense of justice. All evil pirates should be eliminated!

Sengoku Marshal: Erza, can't you obey orders? Sometimes this world isn't just about passion; there's also human relationships involved. Hey, don't give me that pitiful look as if I'm bullying you.

Hawkeye: I never imagined a girl could reach this level in swordsmanship. Erza, you are a worthy opponent.

Wang Luffy: Everyone run! If the opponent is Erza, we'll really be killed!

Erza: My justice is the sword in my hand. Pirates, you can't escape! Hahahaha!

My name is Kira Nanami, I'm 33 years old, a graduate of Tokyo Jujutsu High School, and single. I currently work for a regular company and exorcise eight curses every day before going home. I don't smoke, and I only drink a little alcohol. Before bed, I always drink a glass of warm milk, then do 20 minutes of stretching exercises, and fall asleep immediately. I never leave stress and fatigue for the next day; even Sukuna says I'm perfectly normal. I go to bed at 11 PM and get a full eight hours of sleep every night. Anything that affects my sleep quality is my enemy. Therefore, overtime is bullshit. Book club: 61 [Kill the Pigeon]

Lin Siya never imagined that a simple outing would lead to her being transported to the 1970s by a mudslide. The 1970s were fine, though resources were scarce, but as an orphan, she didn't mind. However, she never expected that it wasn't just a simple time travel, but a transmigration into a book, becoming the female protagonist's comparison point.
