Ye Yu, an ordinary Chinese girl, died and was honorably inducted into the great army of those who transmigrate.
Her first transmigration sent her to a place crawling with monsters, where humans struggled to survive. There, she was tempered and grew stronger. In the end, despite being a delicate young girl, she founded the Night Watch Corps, which defended the front lines against the monsters, wielding an iron sword to protect the hard-won peace of the people.
And now, she has transmigrated once more.
[My Hero Academia], [Demon Slayer], [Akame ga Kill!], [Fate/Zero], [No Game No Life: Zero]...
These were countless anime worlds she had nearly forgotten.
Even so, as long as there are civilians here who need protection, what she must do will never change.
"I don't care who you are or why you're fighting. If you dare turn your weapon on the people, I will take up my sword and stand in your way."
The girl held a longsword forged from ordinary iron loosely at her side. Her beautiful black hair trailed behind her like a cloak of night. Her expression solemn, she spoke slowly, one word at a time, in a clear voice.
"I will fight to the death."
The girl's name was Ye Yu.
She was a... Night Watcher.
