Focus

A Focus (焦点, Shouten, Focal Point), otherwise referred to as Great Maiden Tools, were a series of priceless artifacts originally conceptualized by the Sixth Kenmeiotome Sylvia Aoi, who then proceeded to share her knowledge with the rest of her kin.

Many considered the Focuses to be highly valuable, due to its high potency and unique interaction it entailed.
