Yousei Teikoku (妖精帝國, literally “Fairy Empire”) is a Japanese unit consisting of vocalist and lyricist Yui Itsuki (伊月ゆい) and composer and arranger Takaha Tachibana (橘尭葉). They draw influences from electro and neoclassical. Through music, Yousei Teikoku is attempting to revive the Fairy Empire that exists between the human world and the spiritual realm known as Spiritua. Yousei Teikoku presents a visual image with gothic style as its core. “Gothic” and “empire” are keywords in their musical concepts. TEAM FAIRITHM has come together to produce this musical revolution.
