Shining Star-☆-LOVE Letter is the debut single Yuka Iguchi, Index's seiyuu. Although she has performed in character songs as found in the ARCHIVES of the series, this would mark her first non-character song. KOTOKO wrote the lyrics of the main track, with sat (fripSide) as a composer, just like SHOOT!, by RO-KYU-BU, the band she took part in. The single was released on February 5, 2013, and contains the image song for the Toaru Majutsu no Index Movie, used for the promotional trailers of the movie.
