Donatella Una

Donatella Una (ドナテラ・ウナ) is a minor character featured in Vento Aureo.

She is Trish Una's mother and was, at some point, Solido Naso's girlfriend. Shortly before her death, she went looking for Solido Naso, making the Boss aware of his daughter's existence and triggering a war between Passione and La Squadra di Esecuzione in order to secure the only lead to the Boss.

History
She lived in Sardinia during her mid-teens, where she fell in love with a young boy named Solido Naso (Also known as Diavolo/Doppio). Though she knew relatively nothing about him, the two had a baby girl, which she named Trish. Though Donatella still loved Solido, he left her at some point, leaving her to take care of the child by herself. She and her daughter lived in Sardinia town for a long time until Trish decided to go looking for her father. Donatella eventually dies of an illness at a Hospital hoping to find Solido.
