Description
Miria Akagi is an 11-year-old elementary school student from Tokyo, standing 140 cm tall and weighing 36 kg, with body measurements of 75-55-78 cm. She has ginger hair, orange eyes, and a gold theme color. Her birthday is April 14th, making her an Aries, and she has AB blood type. She is left-handed.

Her personality is boundlessly energetic, consistently cheerful, positive, and enthusiastic. She became an idol driven by her love for all things cute, specifically to wear cute outfits, sing cute songs, and perform cute dances, reflecting her straightforward, childlike perspective. Highly sociable, she enjoys conversations and acts as a mood maker who uplifts others. Her significant curiosity is a noted charm point, sometimes leading her to explore staff room equipment. Despite her generally youthful demeanor, she occasionally displays maturity, such as playfully calling the Producer "cute." Having a younger sister contributes to a reliable, older-sibling aspect.

Relationships are central to her idol activities. She maintains friendships and unit memberships with idols including Arisu Tachibana and Nina Ichihara in L.M.B.G., and Momoka Sakurai in both Caper Parade and L.M.B.G. Additional unit connections include Hiromi Seki, Yumi Aiba, and Frederica Miyamoto in Caper Parade, and Kirari Moroboshi and Rika Jougasaki in Decoration. Uzuki Shimamura and Mika Jougasaki find her extremely cute. She associates herself with raccoon dogs, reflecting her affinity for playful and charming imagery.

Her development shows consistent dedication to idol work while retaining core traits. In the U149 spin-off, she expresses specific dreams like conducting handshake meet-and-greets. Across media, she maintains optimism while navigating challenges as a younger idol. Her interactions reveal a thoughtful side, such as advising that extensive talking isn't necessary for connection – simply being present with others can suffice. This balance of enthusiasm and occasional insight demonstrates growth without diminishing her inherent joyful nature.

Her idol activities span multiple events and units. She appears in events including "Orange Sapphire," "Hi-Fi☆Days," "shabon song," "Yes! Party Time!!," "Aozora Yell," "THE VILLAIN'S NIGHT," and "Natsukko Ondo." Instrumentally, she plays castanets in Mobamas and trumpet in Deresute for the Little Marching Band Girls unit.
