When you are a full ninja, go into the Ninja Hideout and take a glimpse of the Martial Arts catalog. As well as the many other things you can buy, you will see the Wind Bracers. Purchase the Wind Bracers. Then, purchase the invisable suit. Put on your mask, suit, belt, and wind bracers. Then, when you wish to say goodbye to a fellow ninja, click the "wave" button and you will vanish in a puff of smoke. For more information, in the Martial Arts Catalog on the side is some information and a little note about each product on the right side pages.
