Presenting himself as "Suzuki," a temporary lecturer at Tōtsuki Culinary Academy during the second-year Final Exams, this individual cultivates an approachable persona through a carefree, charming demeanor and attractive appearance. His casual attire, typically a dark dress shirt and trousers, reinforces his charisma. This identity is an alias for Asahi Nakiri (formerly Asahi Saiba), used to infiltrate the academy. As Suzuki, he delivers lectures rich with exceptional culinary knowledge, framing them as interactive gatherings rather than traditional lessons. He specifically targets Yukihira Soma, the Elite Ten First Seat, initially mistaking him for a latecomer before recognizing his status. Suzuki challenges Soma to an unofficial Shokugeki after class, promising to reveal a "secret" about becoming a true chef should he win, while demanding Soma's knife as his prize. Judged by Megumi Tadokoro in their pork cutlet duel, Suzuki replicates Soma's Cheese Fondue Pork Loin Katsu Combo Meal, enhancing it by substituting Chantilly sauce for the cheese sauce. His victory demonstrates superior technique, though he returns Soma's knife after deeming it inferior to one he already possesses. Following this defeat, Suzuki discards his alias, revealing himself as Asahi. He discloses his background as the former protégé of Soma's father, Joichiro Yukihira, who trained him in America during Soma's childhood. Asahi expresses jealousy towards Soma as Joichiro's biological son and declares his intent to marry Erina Nakiri to "become stronger," claiming he alone can satisfy her God Tongue. This revelation precedes his abduction of Erina for the BLUE culinary tournament. Asahi's past explains the Suzuki alias: born to an American mother and Azami Nakiri, he endured childhood abuse before meeting Joichiro at an orphanage. Joichiro's mentorship inspired his culinary path, but the mentor's departure to raise Soma fostered deep resentment. As part of the underground group "Les Cuisiniers Noirs," Asahi developed the "Cross Knives" technique, defeating chefs worldwide and confiscating their knives to augment his skills. His infiltration as Suzuki facilitated access to Erina and Soma. After his exposure, Asahi abandons the Suzuki persona entirely. He competes in BLUE under his true name, initially displaying arrogance before ultimately losing to Soma in the finals. This defeat catalyzes personal growth, leading to his acceptance into the Nakiri family and a more subdued demeanor.
