Game theme song
The single was released before the release of "Rewrite," featuring the opening theme "Philosophyz" and the first time the ending theme "Yami no Kanata e" was included. Together, these two songs form the main body of this music release.
Three types of inclusion
The album has six tracks, with each song available in full vocal, Game size, and off vocal versions. This arrangement allows readers to distinguish between game performances in length, full songs, and silent accompaniment.
NanosizeMir's involvement
KSL Live World's official introduction lists "Philosophyz" as NanosizeMir's signature song for "Rewrite." The group consists of singer Runa Mizutani and composer Yuichiro Tsukakoshi, who later participated in related music for the anime adaptation.

Music related to "Rewrite+" is included in Track 1 of the first disc of the "Rewrite Original SoundTrack." The album was released on 2011-10-28.
2011 Arrangement, performance, and mixing of the original song
a2c's original production record states that he handled arrangement, performance, and mixing, balancing I've's style in previous Key songs with his own vocal processing. The guitar riff of the chorus was specially designed.
Switching to guitar and playing
a2c notes sections A and B in B♭ minor, with choruses and other parts changing to G minor, and recommends the entire piece in E♭ tuning for those who want to play guitar parts. These notes correspond to the arrangement of the original 2011 song.
Recording and singing experience of the original song
Runa Mizutani recalled that the original "Philosophyz" was her first major project completed alone in front of a professional studio microphone. She recorded under tension and pressure, receiving support from staff such as Shinji Orito.
