Isami Aldini (勇·阿爾迪尼]いさみ アルディーニ) is a 92nd Tōtsuki Generation student and alumnus. As well as the younger twin brother of Takumi Aldini. By his third year, he obtained a seat in the Elite Ten Council.
Born into a Japanese-Italian family, Isami grew up in Italy along side his twin brother Takumi. In their youth, they worked for their uncle and father in their family restaurant, Trattoria Aldini. He had a healthy brotherly relationship with Takumi, though in most aspects, Isami was better than Takumi. However, in the kitchen, Takumi proved superior as many of the restaurant's patrons would specifically request a dish made by him. Isami became jealous and eventually revised one of Takumi's dishes to match his brother, only to be scolded by his father for doing so after unintentionally dulling the taste. In tears, Isami apologized for ruining his dish as he wanted to be as good as Takumi. Takumi consoled him, telling him that that he's only good whenever Isami is around. Takumi and Isami made a promise to work together, improve their skills, and eventually make Trattoria Aldini the number one restaurant in Italy.
