Don't let this young girl's serious appearance fool you, with the black and red dress with a big 'ol scythe, she looks a little intimidating right? Right!? The kid's a downright bubbly dork. Randomness incarnates! With a super squeaky, bubbly voice to boot! One conversation with her and suddenly that intimidating aura immediately gets thrown into a fiery dumpster! Errm... anyways! Ruby is a self-proclaimed dork when it comes to weapons; she is quite intelligent, having designed and built Crescent Rose, although she admits to going "a little overboard" with its design. She feels that seeing new weapons "is like meeting new people, but better." She relies on Crescent Rose (that big 'ol scythe) quite often in battle, which implies that her weapon is the source of her confidence in battle. Ruby has a strong sense of moral justice, a trait she obtained from stories about heroes and monsters that her sister used to read for her, as well as the way her parents raised her. These stories are what gave her the ideals that she wished to live by and uphold throughout her life, and are the reason for her love for books. Because she is shown to be childish even when in class, she tends to study by herself to cover the necessary knowledge. Despite this, Ruby's leadership skills make her a worthy teammate. While she may occasionally act without thinking, sometimes she seems to understand the situation better than most. She can then use this ability to quickly formulate plans.

She sounds super bubbly, a little hyper with a bit of a squeaky voice, and can say some pretty random stuff when in battle, definitely gets under her foe's skins.
