Tonio Trussardi

Antonio "Tonio" Trussardi is a professional chef of an Italian restaurant named "Trattoria Trussardi" at the edge of the town of Morioh. Since he runs the entire business alone, he can only serve up to two tables at a time.

Appearance/Personality
Tonio has a charismatic and courteous personality – unless someone dares to de-sanitize his kitchen, in which case he turns vicious. His ambition is to serve his customers tasty and especially healthy delicacies.

History
Tonio did extensive studies in cuisines all around the world, and is extremely proud and confident in the skills he accumulated. During his travels around the world he developed his stand Pearl Jam, allowing a much better cooking ability, but no one in his country Italy recognized his new ability. Due to being too young he couldn't open his restaurant in there, so he traveled to Morioh where the competition betwen restaurants is more intense and his chances were bigger.

Diamond is Unbreakable
Okuyasu Nijimura and Josuke Higashikata found Tonio's restaurant in Morioh and decided to visit it. Tonio presents himself to be different from other chefs, as he doesn't have a menu and the food he prepares is decided by himself after examining his costumer's hand to see its ailments. He examines Okuyasu and serves him what would be better for his body, but Josuke grows suspicious of him after several weird incidents with Okuyasu after eating the food. Okuyasu's intestines are ejected from his body and Josuke enters Tonio's kitchen to battle him, discovering the food had the presence of the stand Pearl Jam. Tonio explains the misunderstanding, saying that his only intention is to prepare delicious food to his clients and Okuyasu is shown to be alright.

He later appears among the stand users warned by Josuke about Yoshikage Kira after Shigekiyo Yangu's death. He promises to keep an eye on his costumers, but only appears again to give goodbye to Reimi Sugimoto.
