Inka is a recurring character in the Oobi series.
Inka is Oobi's piano teacher. Grampu has a crush on her; he tries not to show it, but it comes across quite obvious. Inka teaches her students to "shake" out their stage fright when they are about to perform.
Inka has fair skin and yellow-green eyes. Her hair is purple, and she normally wears jewelry.
