Madara Mikejima cultivates an energetic, overly friendly persona, constantly calling himself "Mama" to project a maternal image. He embraces this role precisely to experience its inherent failure, recognizing his limitations. Though his jolly nature spreads cheer, his brutal honesty and disregard for personal space often frustrate others. He exhibits fierce protectiveness, readily defying morals and social norms, resorting to threats or violence to safeguard those he cherishes. Diverse talents make him dislike comparisons, fostering isolation despite his capabilities. Professionally, this isolation manifested early as the solo idol "MaM".
Physically imposing, Madara is tall, strong, and energetic. His long, spiky brown hair is styled in a half ponytail with braids on both sides. Teal eyes and a preference for unbuttoned uniforms complement his bold aesthetic. Distinctive MaM stage outfits feature cowboy boots, fedoras, and star motifs; specifically, a black, grey, and white jacket with gold lining, a green vest, black pants tucked into brown boots, a red scarf, and a star-shaped brooch.
His childhood was marred by familial strife within the devout Shinkai religious group, which worshipped his friend Kanata Shinkai as a god. His parents held corrupt influential positions – his mother in the underworld, his father as police chief – turning their home into a yakuza-like environment, souring relationships with them and his sister, Maguro. Madara secretly provided Kanata torn magazines, challenging his deification by showing the outside world. A pivotal moment came when Madara wished for Kanata to cure Maguro's illness; Kanata's inability fueled Madara's resentment towards the religion. He dedicated himself to dismantling it to free Kanata, simultaneously harboring bitterness over his sister's condition. This led to ostracization by the group and estrangement from Kanata.
At Yumenosaki Academy, Madara served as captain and later vice-captain of RYUSEITAI's first squad, managing slackers and hoodlums who only cooperated under his watch. He facilitated Kanata's entry into RYUSEITAI, assigning him the Ryusei Blue title. A strategic deal with Keito Hasumi allowed him to operate as MaM, the academy's only solo unit, offering flexibility but deepening his isolation. The Shinkai group and Tenshouin Zaibatsu frequently forced him to travel, separating him from Kanata.
Later, industry shifts favoring units over solo idols impacted Madara. His family partially disowned him for dismantling the Shinkai religion, severing connections and forcing MaM into hiatus. He then collaborated with Kohaku Oukawa to form the temporary unit Double Face, targeting the corrupt GFK syndicate. Their "business transaction" partnership evolved into mutual respect. Producer Anzu leveraged a "Marble Cast" rule banning solo acts to pressure Madara into continuing Double Face, concerned about his solitary path. Though disbanded to eliminate future "seeds of anxiety", Madara maintained MaM as his "day job", acknowledging Kohaku's occasional performance support.
Relationships reveal his protective yet manipulative nature. He exaggerated a childhood connection with Anzu to infiltrate Trickstar, though she later offered genuine support. He harbored hostility toward Eichi Tenshouin for exploiting Leo Tsukinaga, contrasting his camaraderie with Wataru Hibiki. His bond with Kanata remained fraught; Kanata resented past abandonment but gradually reconciled upon recognizing Madara's efforts to free him. Chiaki Morisawa admired him as a hero despite differing justice ideals, while Shinobu Sengoku viewed him kindly for ninja souvenir gifts. Leo Tsukinaga received Madara's unwavering protection, notably during GFK manipulation.
Madara possesses extensive skills: multilingual fluency in English and French, proficiency in piano, cello, and violin, culinary expertise, sports aptitude, and licenses for motorcycles, helicopters, and small aircraft. He also repairs machinery and instruments. These abilities stem from dedicated practice under a mentor but exacerbate his loneliness by setting him apart. A cat motif, linked to his childhood nickname "Miike," underscores his stealth despite his stature.
