The voice actresses formed a unit in February 2010 and made their singing debut in June 2010.
Project Milky Holmes began in February 2009, and Mimori, Tokui, and Kitta started a radio show in December 2009.
Suzuko Mimori, Sora Tokui, Mikoi Sasaki, and Izumi Kitta — the main voice actresses and singers in the Project Milky Holmes multimedia franchise — announced on Saturday that they will hold their last live concert next February.
The project will hold a “Milky Holmes Road to Final” campaign between now and then, including an event in June.
