I've been trying to look everywhere...I think Kabuto, Kajiki, and Tora Origami were the ones to each come with this weird yellow piece and I still have no idea what in the world they're for? Am I missing something obvious? :shakefist
It's a "support piece" for Shishi Origami since the poor thing takes on a lot of weight in Kabuto ShinkenOh, Kajiki ShinkenOh, and Tora ShinkenOh. Also for safety reason, I think... since you could accidentally hurt your fingers.....?
