Revenge of the fifth

Lexy RedFox is the youngest offical assassin the world has ever seen. The problem is can a certain red haired boy make her see differently from her usual cocky self? Or will she tell the entire class about Korosensei's true intentions, his secret, his promise, he made that one fateful day. The only problem is will her past get in the way of her falling in love? Good f**king luck Lexy.
