Yūta Mirako, a second-year student at Shishiku Academy, possesses lilac hair styled in a curtained part and striking violet eyes. Standing 175 cm tall with a slender 58 kg build, he typically wears a purple sweater and necklace beneath an unbuttoned uniform jacket.

His personality presents a pompous exterior with a "haraguro" nature—outwardly amicable and friendly while masking manipulative or cruel undercurrents. He maintains emotional distance from others, often seen with a grin as he guards his true self.

Mirako's background includes a dominant delinquent reign in middle school, ruled through sheer strength. He abruptly transitioned into an idol career for undisclosed reasons, forging a dual identity as a public figure with impenetrable hidden depths.

In *Kenka Banchō Otome: 2nd Rumble!!*, his sharp perception uncovers Hinako’s gender early. Upon learning of her bond with childhood friend Kira Rintaro, jealousy drives him to compete for her reliance. After witnessing Hinako’s cross-dressing contest performance, he recruits her for a yankee-themed drama. Using his industry experience, he coaches her through acting challenges like line delivery and natural expression. During production, he defends her against a dismissive co-actor and thwarts sabotage attempts by the Masakari yakuza. Their relationship culminates romantically when he accepts her Valentine’s chocolates exclusively as a love confession, leading to a mutual kiss.

His abilities include proficient kickboxing that complements his delinquent prowess and polished idol performance skills. His combat strength rivals Kira’s, reinforcing his formidable reputation.

Mirako shares a competitive yet respectful history with Kira. He leverages his idol connections to resolve conflicts, such as publicly discrediting antagonists to protect Shishiku Academy.
