This is Spica, one of the companions of Shun in training who didn't get the Andromeda cloth (armour). Hence, they turned rogue and using some unknown Cloths fought against Shun Andromeda with predictable results for them.

Anyway, a cool character and one that Bandai has decided not to make yet and probably never.

I used a Myth Cloth as base figure, and then more or less sculpted everything, nearly all armour has been sculpted, as well as hair.
