DIALOGUE+ is an eight-member female seiyuu unit under the Pony Canyon label. The group introduced itself with the digital single "Atarimae dakara (あたりまえだから)", released on June 17, 2019, shortly before the official announcement of the unit on June 24, 2019.
The unit made its formal recording debut with the single "Hajimete no Kakumei! (はじめてのかくめい！)" on October 23, 2019, and followed it with the mini album "DREAMY-LOGUE" on April 8, 2020, establishing its early identity as a seiyuu-driven project in the Japanese pop and anime music scene. On February 3, 2021, DIALOGUE+ released its second and third singles, both linked to the opening and ending theme songs for Jaku-Chara Tomozaki-kun, a connection that helped define the group’s place among contemporary anime song acts.
In 2025, DIALOGUE+ continued its anime theme song work with a music video for the opening song from Possibly the Greatest Alchemist of All Time on January 8 and a music video for the ending song from I Want to Escape from Princess Lessons on February 25. The group also released the music video for "Joyful Sciante!" on September 16, 2025. The members of DIALOGUE+ are Yurina Uchiyama, Nene Hieda, Kyouka Moriya, Yuuna Ogata, Ayaka Takamura, Satsuki Miyahara, Mayu Iizuka, and Manatsu Mirakami.
