Shō Kurusu is a 16-year-old male with a June 9 birthday, placing him under the Gemini zodiac sign. Standing 161 cm tall and weighing 52 kg with blood type O, his stature earns him the nickname "ochibi-chan" (shorty) from peers, visibly irritating him. Despite this, he consistently displays a cheerful, energetic, and positive personality.

He shares living quarters with roommate Natsuki Shinomiya. Shopping ranks among his hobbies, and he holds profound admiration for Hyūga Ryūya, whom he idolizes. Both Ren Jinguuji and Shō himself note his tendency toward clumsiness, especially in tasks requiring manual dexterity. His primary artistic focus is the violin, reflecting dedicated musical development.

Within the narrative of the special, Shō joins his group following their "Maji LOVE LIVE Kingdom" success. The members navigate a blend of fulfillment and uncertainty about their future when invited on a "glamping" (glamorous camping) reward trip. This excursion serves as relaxation and team-building, revealing group dynamics away from professional performances. As a behind-the-scenes interlude linking their past concert to upcoming endeavors, it highlights camaraderie through shared experiences like campfire gatherings.

No significant character development or background alterations occur for Shō in this special. His core traits—enthusiasm, intermittent clumsiness, violin focus, and reactions to his nickname—remain unchanged, with emphasis placed on group interactions during downtime rather than individual progression.
