I Want to Be a Saint, But I Can Only Use Attack Magic!

Why can’t my embarrassing past just disappear?!
“You’re always alone.” From the bottom of her heart, Yuffie Abisus desperately wants to be a saint for one reason only—so no one will ever say those aggravating words to her again. Fortunately for her, she’s been blessed with an extraordinary supply of mana despite being a commoner. Determined to succeed in her mission to become a saint and have everyone fawn over her, she enrolls in the Academy of Magic where she’s sure to free herself from her gloomy life. However, Yuffie has a secret. For whatever reason, she can only use attack magic, which itself falls strictly in the domain of men. Meaning she’s incapable of utilizing healing magic, women’s magic. Maybe that’s why she ends up being labeled a second-rate student and isolated from the rest of her cohort from day one.
So begins the tale of a girl who’s a smidge socially inept, disheartened by her struggle to make even a single friend, and once more mired in the drudgery of a loner life. A girl who, in spite of the challenges she faces, pushes herself ever onward to achieving her goal of sainthood!
