Business Ninpo: Caltrops is one of Answer's Special Attacks, first appearing in Guilty Gear Xrd Rev 2.
Overview[]
Answer rapidly throws a business card to his opponent's feet, which glows with a green aura while stuck in the ground. The version, indicated by a (一, Ichi?, lit. One) on the back, travels for 1/3 of the screen - while the version, indicated by a (二, Ni?, lit. Two), travels a little over 2/3. Each card lasts 12 seconds in the ground, or until another one using the same button is thrown.
While the card(s) are still in the ground, Answer can follow up with either:
While both follow-ups can be used without needing to use Business Ninpo: Caltrops, their effects will not occur; Under the Rug will have Answer disappear on the spot, and Under the Bus will only have Answer use the hand seal.
