- Purchase the song pack "Battle CHAOS 2019" in the Black Market.
- In the Cytus II MM Star Show held in Xiamen, this song was played in the final round before it was released.
- This song is a remix of iL, extinguisher and Re:incRnaTiØN ～夕焼ケ世界ノ決別ヲ～ remix, so parts of those songs are heard throughout the song.
- The reason for choosing iL and Re:incRnaTiØN is they were the songs chosen to be played in the finals of Cytus II JP Battle -CHAOS-. Ice asked for a mash-up and a re-arrangement of them in the Cytus II MM Star Show in order to make a surprise.
- lixound is the composer of extinguisher, so he added its melody to this song as well.
- In the aforementioned Cytus II MM Star Show, the difficulty ratings were listed as iL, X, and RØ for Easy, Hard, and Chaos respectively. They represent iL, extinguisher, Re:incRnaTiØN, referring to the melodies used in the song.
