The band was created in 1999 with Shinobu [Vocals], Ayame [Guitar], Yass [Bass] and Shun [Drums] called "ARK". After a first single whose name was "14 Banme no Kane no "Koe"", Rin [Guitar] got in the band. They recorded 2 CD with him, like the album "Mayu". In 2000, Ayame left the band : he is substituted by Masaru. After the releasing of "Symbiosis ~Sousei no Hitsuji to "Susumu" ka "Fuka"", Ayame came back in the line-up of Delta Ark to substitute Masaru. But not for a long time, because he will start off again few time later. Delta Ark, saw aux Yass [Basse] and Shun [Batterie] start off too. Japanese players changed the band's name to "De-ARK". Even without 3 members, the rest of the band, they succeed to continue. Louis [Guitare], Shiori [Basse] and Mayu [Batterie] integrated the band later. They realised together the EP "Case", and then Shiori and Mayu got out of the band. Delta Ark found Saga and Yuu for the final line-up and his definitive name : they renamed it "Delta Ark". The last musicians integrated different groups in which they play now.
