The first major new album by the legendary rock band kein. This long-awaited new work, their first in about three years since the previous work "Hakai to Sozo" (indies distribution), is an ambitious record with all songs newly recorded. The band's world like no other, which has steadily evolved since their major debut the year before last, at last reveals itself in full. The Limited Edition is a luxurious format with a Blu-ray containing "The Messy-Haired Grimalkin" Music Video and "The Messy-Haired Grimalkin" Music Video Making, plus a special outer case.
