Shirataki (Japanese: シラタキ Shirataki) is a character of the day who appeared in Aiming for the Top Floor!. She is one of the ninjas in the Kantonian Gym, and is in charge of its third floor.
Shirataki gave Ash and his classmates a target trial, where the aim was to hit a target with three shuriken. Ash and Kiawe were successful, but Lana outshone them by hitting three different target boards with ease. The trio was subsequently able to advance to Charlie Charma's floor. Lillie's aim, on the other hand, was so poor that it endangered everyone else, and she was forced to remain on the third floor to perfect her throwing technique.
