Dita Liebely is the main female protagonist of the series. During the invasion aboard the Ikazuchi, she is one of the three Dread pilots whose dread were exposed to Paexis's light.
For a fighter Dread pilot, Dita has a strange personality. She is bubbly and cheerful, and she has a positive and naive outlook in life. This cheerfulness appears in every aspects of her life, even in battle. No matter what the situation is, she always had a smile on her face, a fact that infuriates Hibiki on some point. According to her, the reason for this laid in the past; when her home unit in Mejere was shut down and upsets the people, she cheered them up by saying funny things and doing stupid things. Because of this, she grew up not knowing how to act in sad situations. Surprisingly, Dita is also a great cook.
She is very friendly to everyone, especially Hibiki whom she called "Uchuujin-san" ("Mr. Alien"). Her straight forward nature earned her contempt from some the crew members, especially Barnette, but she never mind it one bit. Her cheerfulness helps the crew to regain their spirits during one vital moment in their battle against the harvesters.
During the second season, her fighting ability grew and she eventually rose to be in the co-leading rank, just under Jura and Barnette.
In battle, she rides a blue Dread, which is a Mejere fighting plane. This dread is one of the three that was exposed to Paexis' light at the beginning of the series and enables it to merge with Hibiki's Vanguard. The result of this combination is a Vandread which was known as Vandread Dita-type or Blue Kachina (Kachina means life bringer), a blue humanoid mecha that possesses two powerful energy cannons with multiple functions, such as shoulder-mounted cannons, arm-mounted lances or cannons, or a powerful javelin when attached together. This Vandread embodies power.

- She was voiced by Kakazu Yumi in the Japanese Dub and Julie Maddalena for the English Dub.
