Movie
Description
Jirō Yamada, the second son of the Yamada family, performs under the rap name MC.M.B. (MC Middle Brother). This 17-year-old eleventh grader stands 180 cm tall, balancing high school with part-time physical labor for the family business, Odd-Jobs Yamada. His appearance features a neck-length black shag mullet with curtain bangs, striking complete heterochromia (a forest green left eye and a gold right eye), and moles under his left eye and mouth. He typically wears a black t-shirt with yellow quarter zippers layered under a sapphire blue-and-white bomber jacket decorated with Buster Bros!!! patches. His outfit includes medium grey ripped jeans, black platform sneakers with blue laces, multiple rings, a red "B" badge, and a smaller blue "M" badge pinned to a plaid shirt tied around his waist. He completes his look with a red-and-navy blue flat-brim snapback hat featuring a sticker under the brim. His Hypnosis Mic is blue with "MB" ring decorations, and his speakers form a rock ensemble with Flying V guitars, amplifiers, and cymbals bearing the Buster Bros!!! logo.
Jirō and his brothers, Ichiro and Saburo, grew up in Ikebukuro’s war orphanage under Tamotsu Ando's care. As children, Jirō and Saburo endured bullying from a classmate, younger Samejima, who targeted them for being orphans. When younger Samejima shoved Saburo, Jirō leapt into his first physical fight to defend him. This act led to extortion by Samejima’s older brother, with Saburo repeatedly giving up his lunch money to shield Jirō. Both brothers hid the bullying from Ichiro. Their trust in Ichiro fractured upon witnessing him assault Tamotsu alongside older Samejima, unaware Ichiro was coerced into debt collecting by Stairway to Heaven. This betrayal fueled Jirō’s resentment toward Ichiro for three years.
The brothers' relationship remained strained after leaving the orphanage. Jirō and Saburo were later kidnapped by their new orphanage director, Gencho Hosen, collaborating with Stairway to Heaven. They were held captive in Ikebukuro Sunset alongside Nemu Aohitsugi, Samatoki Aohitsugi’s sister. Gencho planned to "sell" Jirō and Saburo upon adulthood, instilling deep fear. Nemu reassured Jirō that Ichiro would rescue them, a prospect seeming unlikely until Ichiro, Samatoki, Ramuda Amemura, and Jakurai Jinguji stormed the building, defeating Mozuku Shito and Gencho. This rescue restored Jirō’s faith in Ichiro.
Following the kidnapping, the brothers moved into a small apartment. Ichiro worked multiple jobs to support them, prompting guilt-ridden Jirō and Saburo to secretly help by delivering newspapers. During this time, they encountered older Samejima robbing an elderly woman. Tracking him to a building, they hid in a locker and witnessed Ichiro rap-battling Samejima. As Ichiro neared defeat, Jirō and Saburo intervened, grabbing microphones to help defeat the Samejima brothers, cementing their roles in Buster Bros!!!.
Personality-wise, Jirō is sociable, athletic, and popular, maintaining a wide circle of friends. He exhibits fierce loyalty to his brothers, reacting with hot-headed aggression to insults against Ichiro. Historically, he idolized Ichiro intensely, mirroring his delinquency and interests in anime and light novels while neglecting his own identity. This evolved after the Division Rap Battle, shifting him from following Ichiro to seeking his own path. He competes with Saburo for Ichiro’s approval, frequently clashing with his younger brother due to their contrasting temperaments—Jirō being physically oriented and impulsive versus Saburo’s intellectual drive.
Jirō’s rap ability, "Rally," unleashes a powerful attack by channeling energy from his teammates. His name reflects his birth order: "Jirō" combines "ji" (二, meaning "two") and "rō" (郎, meaning "son"), while "Yamada" signifies "mountain" (山) and "field" (田). Post-Division Rap Battle, his school popularity increased. His hobbies include soccer, skateboarding, and running, though he rarely plays guitar despite occasional depictions. He is associated with the quote: "We don’t stop playing because we grow old; we grow old because we stop playing."
