Ugetsu Kageuchi is Setsuka's primary weapon. A hidden Iaito Iai sword concealed in the handle of an oil paper parasol, similar to shikomizue or shirasaya styles. Nothing is known about this weapon, but it is speculated to be a gift from Setsuka's master. Ugetsu Kageuchi, when directly translated, means "cormorant moon, darkness inside". Iaido is easily confused with the sword style of Battōjutsu, but Iaido concerns itself primarily with the drawing, cutting and re-sheathing of the sword, while battou-jutsu focuses only on cutting technique. Setsuka's official profile states she uses battou-jutsu but judging by her actual style, it resembles Iaido.
