Here it is Geist, leader of the Ghost Saints. The best character of the Ghost Saints, with the more "conventional" armour. She is (yes, she is a she) the sister of Shaina of Ophiucus (or in some dubbings just friend). She fights against Seiya and his friends and she is defeated.
Made with a Shiryu Dragon figure, Hydra feet, Hyoga leg protections and body armour, Aioros arm protection and Ikki hands, the rest grey sculpting.
