Syl

Syl, a claymore with a shaved head and usually dressed in a tight dark outfit. She is associated to the Vanguards and was assigned as bodyguard to Baroness Van Lachery. (c61) Her ability, "Eye of the Sovereign", enables her to control Yoma. She perfected this ability with Icolde's help. In actuality, it is unknown if she is an awakened or claymore since no mention is ever made of her eye, skin, or hair color which could determine if she was one or another although she has been referred to indirectly as a Van lachery's claymore bodyguard.

The contract of the Vanguards with Baroness van Lachery doesn't allow Syl to disobey orders from her and forces Syl to protect her at all costs. She admires the baroness, seeing her as a genius and above her. She must ask for permission to speak when conversing with the Baroness. She nearly failed her mission when Baron Van Sturm nearly killed the baroness, taking out her eye and cutting off her right arm. Syl started a special emergency treatment to keep Van Lachery alive, stating that she wouldn't like the outcome but it was necessary.(c66)

Syl was able to successfully save Van Lachery, and Brook was able to give her a surgery to give her an eye and an arm.
