Maika is a 16-year-old girl who despite having a positive and cheerful personality, unintentionally gains a sadistic look in her eyes whenever she smiles.
This look catches the attention of Dino, who scouts her to be the 'sadistic girl' waitress at café Stile. Despite being told that the customers like being treated badly, her worrying about how she is treating customers gets the better of her, causing her to snap into an apologetic personality as soon as they have left. She comes from a very traditional family and works part time so she could study abroad using her own money. Her love of other countries also makes her develop an admiration towards Colonel Sanders (whom she refers to as the "old man from the chicken place") and Santa Claus.
She adores Dino because of his blond hair but is oblivious to Dino's crush on her.
