Let's post Vega something else too.
Vega's my second OC from Yu-Gi-Oh Zexal (Season II)
Her origins are Astral, she's the daughter of the Astral deity but following her wish and wanting to save "the human souls of seven stars from the darkness" she incarnates as a human and several times tries to prevent the darkness from completely taking over the souls of the seven (from this the Mithyrian Numbers are created by the deity as Astral's part)
[in the pic she looks like herself in Alit's past and also in Astral form, a priestess of a local goddess.]
During the second season, he takes on a human form and joins Yuma, Rio, Shark and the others; crossing paths with Vector but also Alit, with whom he will bond since he discovers his ties with a "lost past". Of course she doesn't recognize him at first and he has a vague memory of a girl who looks like her. Yet, the two become friends.
During the arc of the Seven Barian Emperors' descent into the human world, Vector notices Alit's behavior (after having followed him over and over again) will attack the girl while the others duel with Yuma's allies and, he'll defeat her when Alit reaches her and reveals the young woman's Astral identity to his Barian companion. From here, thanks to the fulfillment of an ancient prophecy, her entire story arises in a new battle for the Barian Empereors...
"On the seventh day of the seventh month, fate can be changed if the star of Lyra continues to shine brightly in the sky. The fallen Astral'll rise again in the Astral heavens and all dimensions will be in danger."
