The Shadow and Dragon Devouring Sword (or SDDS for Short) is a sword created by Yuuto Kiba in hopes of killing Ichiro if he ever was overwhelmed by the dark version of himself. So far the only ones who know about the sword are Ichiro Lucifer, Gray Dantalion, Issei Hyoudou and Yuuto Kiba in hopes of keeping it hidden from Rias, Serafall, and Sona (out of fear that they wouldn't allow Kiba to use it on him).
