In the anime, Dark Repulser is aqua-colored. Its grip is a darker color than the rest of the blade and is completely straight. It leads up to a crossguard that is exactly perpendicular to the grip and is designed to look like a pair of conjoined dagger blades.
At the center of the guard is a large aquamarine gem. The blade itself is a deep aqua color, the base of the blade has a light-aqua attachment that causes the blade to have a natural indentation when one traces its length due to the angle that the attachment bends at.
The light novel describes Dark Repulser as a pale, one-handed straight sword that is slightly transparent. Its blade is white and slender, though not to the extent of a rapier. The grip is silver, with a slight tinge of blue.
Elucidator is a pitch black sword with trims of gray and is evenly balanced and quite powerful. It has a black hilt connected to a hand guard that drops down on the right side. Attached to this elongated area of the hand-guard is part of Elucidator’s blade so as to better aid the user in retaining their grip on the sword when it is being used. The blade is completely black like the rest of the sword and the said blade is outlined in a light gray. In the design art by the illustrator of the novels, a small cross is emblazoned on the flat of the blade, just beneath the tip.
