At their TV Tokyo Ongakusai 2020 Autumn performance on September 30, Morning Musume '20 debuted a new song called "Junjou Evidence" ("Innocent Evidence").
The song is Morning Musume's trademark idol EDM, with solo lines for Oda Sakura and Sato Masaki (and possibly more in the full version). Additionally, while the credits are unknown at the time of writing, it has been teased as a Tsunku song. The song has not been announced for release yet.
