Speculation time!! She'll either:
 * 1) be revealed as the most broken character in the series with the exception of her Achilles' heel (he was invulnerable to anything that didn't hit his heel -- although earlier stories don't say that Achilles was invulnerable and in fact received wounds several times)
 * 2) have been forced to dress up as a boy to avoid being taken to who-knows-what (as Achilles was dressed up as a girl so he wouldn't be taken to war)
 * 3) had her weapon forged by someone (who will become) really important for her to take revenge against a person that hurt/killed her best friend because of her own arrogance (Achilles refused to participate in the Trojan War until his best friend Patroclus' death at Hector's hands)
 * 4) be revealed to have been taught by a Faunus (apparently, Achilles was taught by a centaur)
 * 5) uncovers her unstoppable rage mode after someone hurts her friend/s (Achilles killed many Trojans while seeking out Hector for Patroclus's death)
