OVA
Description
Shogo Itaya appears across the "given" franchise, including the manga, anime series, "given: Hiiragi mix," and "given: To the Sea." He is a close friend and classmate of Ritsuka Uenoyama and Ryu Ueki since their first year of junior high. Their group often spends breaks at the basketball court and later includes Mafuyu Sato.

Physically, Shogo has short, messy orange hair, thin eyebrows, and orange eyes. His typical attire features a raised-collared black jacket with two orange buttons over a dark yellow shirt. For basketball, he wears a red-collared jacket over a white shirt. Alternate depictions show him with dark, parted hair revealing his forehead, trousers with parallel white lines and rolled-up legs, and laced trainers.

Shogo's personality is cheerful, approachable, and eager to include others. He demonstrates care by inviting Mafuyu to play basketball and complimenting his skills. He openly questions Ritsuka about his growing closeness with Mafuyu. Energetic and supportive, he frequently suggests basketball during breaks, assures Mafuyu he'd attend his live performances, and offers to play basketball anytime.

Born on May 20 (Taurus, blood type O), he stands 176 cm tall. He attends the same high school as Ritsuka and Mafuyu, enrolled in the science class. Though basketball is a regular lunchtime activity, his true athletic passion is football (soccer), where he excels as a forward. He gains recognition as one of the Kanto region's most famous strikers, attracting professional club interest before graduation. He also enjoys music and attending Ritsuka's band performances.

Shogo appears frequently in school scenes: trying to wake napping Ritsuka during breaks, discussing Ritsuka's interactions with Mafuyu, sharing comical drawings of Ryu Ueki in class, observing Ritsuka's reaction when Mafuyu declines to join the band, and witnessing moments between Ritsuka and Ayano Kasai. He attends friends' live shows, noting Ritsuka's venue reputation and expressing high expectations for Mafuyu. At one concert, he reacts with visible surprise to the audience's response and Mafuyu's singing.

His name combines "翔" (sho, meaning "soar" or "fly") and "吾" (go, meaning "I" or "me"). His hobbies include various ball games: soccer, basketball, baseball, volleyball, tennis, and handball. He has been seen wearing a T-shirt possibly referencing "My Chemical Romance." His age progresses from 17 in high school to 18 in his third year and 28 in the "10th mix" timeline.
