Johnny Beppu, nicknamed Johnny Bepp, energizes Starlight Academy as a vibrant dance teacher and homeroom instructor, guiding generations of students from Ichigo Hoshimiya to Akari Ōzora. His signature shoulder-length ash brunette hair, green eyes, and groomed mustache-goatee pair with bold track suits in green or red, crafted by former dance partner Sunny. A theatrical spirit, he peppers conversations with English phrases and whimsical nicknames like “Starmiya” for Ichigo or “Coolkawa Teacher” for colleague Naoto Suzukawa.

Before shaping idols, he dominated global stages as half of Sunny & Johnny, the legendary “Kings of the Dance World.” His mentorship extends beyond choreography, arranging auditions, securing elite designers, and even concocting tomato juice to enhance Yurika Tōdō’s vampire persona. He shares a steadfast alliance with academy headmistress Orihime Mitsuishi, fondly dubbing her “Academy Mother,” and once nurtured the idol group Masquerade.

Family unveils another layer: he raised younger sister Elisa Bepp after their father’s death, struggling to release his protective role during her wedding. Determined to master ballroom dancing for the event, he enlisted Tiara Yumesaki’s aid. Though typically boisterous, he shifts to stern authority when student safety is jeopardized, as seen when halting Rin Kurosawa’s injured rehearsals.

His flair for comedy shines in in-universe parodies, portraying an alien in *Idol Universe War ‘Ozoracon’* or a delinquent challenging Juri in *Aikatsu Teacher*. Post-Starlight lore hints at a moonbound eternal dance in *Aikatsu Dive!*, while a recurring gag nods to his wary avoidance of designer Maya Yumekoji after a botched delivery.

Trivia traces his stage name “Johnny” masking his true identity, with dance poses parodying Michael Jackson and a pirate costume nodding to Johnny Depp’s aesthetic. The transition from green to red track suits mirrors renewed synergy with Sunny, symbolizing evolution despite his storied legacy.
