The Linkle Stones are inserted into the Linkle Smartbook and they all have a different usage to help with Ha-chan's growth. The stones produce different kinds of food or drinks for Ha-chan and sometimes allows her to change into different forms. The stylus can be used not only to draw things on the smartbook's screen, but also in the real world as well, first creating a key to open the door in episode 19. The stylus also doubles as Kotoha's magic wand.
