OVA
Description
Born into a Japanese-Italian family operating Italy's Trattoria Aldini, Isami Aldini is the fraternal twin brother of Takumi Aldini. Childhood saw Isami excel in most areas yet develop an inferiority complex over Takumi's superior culinary skills, as patrons specifically requested Takumi's dishes. After Isami revised Takumi's dish and received paternal criticism, Takumi consoled him, forging their promise to jointly elevate Trattoria Aldini to Italy's top restaurant.

Initially obese with spiky brownish-black hair combed backward, cartoonishly small eyes, and prominent shark-like teeth when smiling, Isami underwent dramatic weight loss before the 43rd Tōtsuki Autumn Election. This resulted in a slimmer physique resembling Takumi, featuring sharper eyes and vanished shark teeth. His weight fluctuates seasonally—gaining in autumn, losing in spring and summer—though he retains taller stature and wild hair. Following a growth spurt, he maintained this leaner appearance through the Beach Exam and BLUE tournament.

Isami displays a calm, jovial, and supportive personality, contrasting Takumi's fiery temperament. He frequently laughs at or teases Takumi, especially when others misinterpret Takumi's brashness. Despite his outwardly peaceful demeanor, he harbors deep-seated pain from his childhood culinary inferiority complex. After Takumi's Autumn Election Quarterfinal defeat, Isami resolved to sharpen his skills to prevent his brother's future failures, demonstrating unwavering dedication to their partnership.

Enrolling at Tōtsuki Culinary Academy alongside Takumi, Isami partnered with him in Hinako Inui's Friendship and Rapport Training Camp session. They collaborated on Aigamo Grilled Duck with Spices, passing the assignment. Isami later advised Takumi to rest before the egg dish challenge, reinforcing his supportive role. For the Autumn Election Preliminaries, he crafted a Curry Bread Calzone blending Japanese and Italian styles, working independently near Takumi while judges praised his innovation. His weight loss during this period surprised peers like Sōma Yukihira and Megumi Tadokoro.

By his third year, Isami earned an Elite Ten Council seat. He continued supporting Takumi during events like the Stagiaire and BLUE tournament, maintaining his slimmer physique and showcasing ongoing culinary growth.
