[Machine Translation] Voice actor Shunichi Toki makes his long-awaited artist debut! The debut single is the ending theme for the TV anime "Midnight Occult Civil Servants" scheduled to start airing in April 2019, and was composed by up-and-coming writer Ryuichi Takagi, with an impressive folklore-style rhythm and a melody reminiscent of a quena. The lyrics were written by a musician who was a big hit in the music scene last year. The lyrics were written by Shungo, who came into the limelight last year for writing the Japanese lyrics to DA PUMP's "U.S.A.," a song that made a splash on the music scene last year. The DVD of the limited first edition includes the music video of "Yakusoku no Overture".
