The album also came in jewel cases as well and there will be ten versions covering all ten members of the group.

Composition
The title track "Last Sequence" is a pop-style dance song with a "wild bassline, drums and synths that makes the melody stand out even more" as it inherits the "splendid concept of WJSN". It contains lyrics that depict another beginning rather than the end. The song is composed in the key of G minor with 121 beats per minute and a running time of 3 minutes and 7 seconds.

The follow-up "Done" is a song with a deep house-base, and a "soft but gorgeous synthesizer sound on top". The third and the Queendom 2 winning song "Aura" is also re-recorded with the inclusion of Dawon who was on hiatus during the finale and it is the only track of the album that will be available for physical copies only. The album ends with "Stronger", a Pop-R&B track which was recorded by Dawon and Yeon-jung.
