Roa Mikaze is a male idol under TSUKINO TALENT PRODUCTION, active primarily in the units infinit0 and pioniX. He has blonde hair, light blue-gray eyes, and stands at an average height of 174 cm, consistent from 2019 through 2021. His personality radiates cheerfulness, friendliness, and flamboyance, paired with a natural talent for communication and building connections. Deeply curious, he cultivates an extensive network across diverse groups. While his abundant enthusiasm sometimes leads to impulsive or moody behavior, the evident lack of malice in his actions means he is rarely disliked. He is recognized for his sensitivity and emotional delicacy, occasionally crying easily. His extroverted and likable nature once made him the center of his original idol unit. He shares an especially energetic and youthful rapport with younger idols within TSUKINO. A notable behavioral trait is his distinctive persuasive tone when asking for favors or items. Associate Takaaki Mamiya describes it as conveying a desire to be pampered, a characteristic potentially stemming from his role as one of the younger members in his initial group where older members likely cared for him. This approach proves highly effective, warranting caution when he employs his signature "honey~" inflection. Professionally, he was recruited into a nationally prominent teenage idol unit. This unit, featuring figures later associated with other groups like Shiki Takamura, Shu Izumi, Takaaki Mamiya, and Rei Sukigawa, achieved significant popularity before announcing an indefinite hiatus in late March/early April 2016. In 2018, he and Rei Sukigawa established infinit0 under TSUKINO PRODUCTION, marking their return. infinit0's concept embraces "0 = no limitations = infinitely free (infinit0)," symbolizing a fresh start and pursuit of unbounded potential. The unit has no fixed leader; Roa and Rei alternate representative duties. Their official introduction highlights their origins as former members of the hiatus-era unit seeking new possibilities and aspiring for free, enjoyable fan interaction. infinit0 has its own mascot, Infeni, a phoenix symbolizing rebirth and endless life, aligning with the unit's name. Roa also participates in the collaborative unit pioniX alongside TOBARI from SUNPRO entertainment, part of the cross-agency X Lied Project. Interpersonally, Roa interacts widely across TSUKINO. Shiki Takamura addresses him familiarly as "Ofuroan," a pun combining the kanji for bathtub (御風呂, ofuro) and his name (呂庵, Roa). He uses given names or nicknames for associates like Rei Sukigawa ("Rei-san" or "Rei"), Takaaki Mamiya ("Takaaki" or "Takaaki-kun"), and Shiou Amagi ("Shio"). Others typically address him as "Roa," "Roa-san," or "Roa-kun." He maintains friendships with numerous younger idols, including Six Gravity members Kakeru Shiwasu and Koi Kisaragi, and Procellarum members Rui Minaduki and Iku Kazemachi, facilitated by his approachable energy. He has a confirmed younger brother. Artistically, Roa admires SolidS' song "DOPE↗ROCK," noting Shiki Takamura's evident enjoyment while performing it brought smiles to himself and Rei. He also recommended "Fabula -Otogibanashi-" from the stageplay *Kuro to Shiro -Purgatorium-* as a compelling song narrating an angelic tale. His surname Mikaze (御風) combines the kanji for "honorable, manipulate, rule" (御) and "wind, air, style, manner" (風). His given name Roa (呂庵) derives from "column" (呂) and "hermitage, retreat" (庵). Trivia notes his birthday coincides with ZIX's Mitsuru Hishida. His stage persona extends into theatrical cross-promotion, given movic's management of both TSUKINO PRODUCTION and the *Kuro to Shiro -Purgatorium-* stage play.
