mothy's fifth album featuring a collection of fifteen new and remastered songs arranged in chronological order released on December 22, 2010. The album is licensed through EXIT TUNES and is available on Apple Music Japan and Amazon.
The booklet contains no lyrics; they were instead printed on a seperate sheet.
The page for each song in the album listed a short phrase alongside commentary from "Ma".
The end of the booklet features a timeline spanning from the year 001 to 999, with the description for 999 burnt off.
The album came with many interactive elements that revealed various secrets—"Ma" introduces a word game on the page for Heartbeat Clocktower that when completed reveals her true identity as "Magician"; aligning punched illustrations over the CD reveals the words "crescent", "mirror", and "twilight" or "Blackbox" and "Solitude"; and aligning a punched illustration over the back of the booklet spells out "たいざいのうつわtaizai no utsuwa" ("vessels of deadly sin").
