Iannis is Antonia and Alexi's only child. He's named after Dr. Iannis, his adoptive grandfather. Because Antonia and Alexi throw themselves into their business ventures and don't have much time to parent Iannis, Iannis grows up helping Pelagia in Drosoula's tavern. He can say several phrases in six languages by the time he's six and he keeps track of how many foreign women have kissed him. He dreams of reaching sexual maturity and of impressing women, and he does what he can to take care of his grandmother. When he's ten years old, he asks Spiridon to teach him bouzouki, but Spiridon starts him on the mandolin instead. Iannis quickly becomes obsessed and soon loves the mandolin more than he likes girls. When Corelli hears him play as a teenager, he believes that Iannis is extremely talented and is going to be a successful musician.
