elfin'

elfin' is a voice actress idol unit. They were formed as a collaboration between Oscar Promotion and voice actor agency Aoni Production through the Zennihon Bikoejo Contest in 2014, from which the three original members were chosen from a pool of 14,434 entries. Their concept is a unit with both good looks and good voices, called a "Bikoejo Unit" (美声女ユニット; Beauty Voice Unit). Their name was chosen to evoke the meaning of fairies, playfulness, and delicacy.
