TV Special
Description
Shōta Mitarai is a 14-year-old male idol who began his career in the group Jupiter under 961 Production before transferring to 315 Production. He stands 163 cm tall, weighs 49 kg, and possesses a slender physique with measurements of 77-60-79 cm. His birthday falls on April 20, making him an Aries, and he has AB blood type. He is left-handed and wears a shoe size of 24.5 cm. His hobbies include sleeping and practicing filial piety, indicative of his strong family bonds.
Presenting an energetic, cute, and charming exterior, Shōta embodies an ideal "little brother" figure. Yet beneath this innocent facade lies a mischievous streak; he strategically leverages his charm to manipulate situations or adults for his benefit. This duality contributes to his popularity. He frequently teases his Jupiter unitmate Touma Amagase due to Touma's gullible nature, while maintaining genuine respect for him and valuing their collaboration. Shōta specializes in dance, particularly excelling at backflips, but is unable to swim—a weakness Touma sometimes exploits. Despite his playful demeanor, he exhibits a large appetite and has been known to trick fellow idols into paying for his meals.
His family consists of his parents and three doting older sisters who sometimes treat him like a "dress-up doll," resulting in him unintentionally wearing cute hair accessories to work. His second oldest sister submitted his idol audition without his consent, motivated by her admiration for his future unitmate Hokuto Ijuuin. Shōta adores his sisters, claiming he has never argued with them and cannot imagine sibling conflict.
Professionally, Shōta transitions from a flippant attitude toward 961 Production's Kuroi (whom he nicknames "Kuro-chan") to a more respectful demeanor toward 315 Production's Producer. He playfully uses his cuteness to gain attention or favors but avoids manipulative tactics like fake tears employed in his past. Though he enjoys being the center of attention, he is reserved socially, disliking interactions with classmates and initially limiting friendships to Jupiter and the Producer. Over time, he gradually opens up to other 315 Production idols like Daigo Kabuto and Takeru Taiga. He often masks genuine emotions with jokes or pranks, such as retracting sentimental statements about Jupiter by claiming insincerity. He considers his family, Jupiter members, and the Producer the only people with whom he can be his true self.
Underneath his cheerful exterior, Shōta possesses intense dedication to his idol work. He relentlessly practices to overcome shortcomings, demonstrated by his fixation on perfecting acrobatic choreography for the Dream Time Circus event after initial failures, and his obsessive solo rehearsals following a dance battle loss to "The Dance King." His dedication extends to protective loyalty; he vows to defend the Producer if they face threats.
In the anime prologue *THE IDOLM@STER Prologue SideM -Episode of Jupiter-*, Shōta and Jupiter navigate independence after leaving 961 Production, facing logistical challenges like volunteer crews and small venues while repeatedly rejecting recruitment offers from 315 Production's Saito. Witnessing fans' dedication—such as crowds waiting post-concert—and a chance encounter with Haruka Amami leads them to reconsider and join 315 Production. Here, Shōta mentors newer idols and reflects on his growth during joint concerts. A pivotal moment involves a cathartic scream during a stressful discussion about venue limitations, highlighting underlying pressures. The special episode *315 Variety Pack! Made In Passion!* features him in vignettes.
Shōta's development emphasizes balancing his playful prankster identity with a profound commitment to his craft and relationships, solidifying his role as Jupiter's youngest member.
