In addition to the previously released CD, Toho will be releasing DVD of the "Daddy Log Legs" musical which is currently in reruns at the Theatre Creation(シアタークリエ) in Tokyo. Theatre Creation will be celebrating its 10th anniversary in January 2018 with reruns and concerts, some of which will include Maaya.
The musical first premiered in September 2012, was initially scheduled for four months but due to popularity was brought back two more times, so the current run is the fourth. It also played in other cities of Japan. Maaya has won an award for her performance.

As far as I know, DVDs of musicals are pretty rare, so it's a either a sign of its performance quality or just a testament to the combined number of fans of Yoshio Inoue and Maaya (Maaya's fanclub IDs are now 6 digits!).
