Michaelo was one of the boys who was sold by Luini to work as a chimney sweep in Milan. Romeo and Alfredo first met him at a shop called The Wildcat in Locarno. While working as a chimney sweep in Milan, Michaelo joined the Black Brothers. Among the members of the Black Brothers, he is the most nervous and the easiest to fool. Michaelo is also called "crybaby" because he often cries.

In the Italian dub "Spicchi di Cielo tra Baffi di Fumo," his name is Michele.
