I do not own the music . It belongs to official project sekai channel and the link will be added to the original source:

   • 【作業用BGM】プロセカ書き下ろし楽曲メドレー（inst ver.）Vol.2  


The only reason i reupload these instrumental versions is to be added to playlists to keep it short

Another alternative title for this song could have been “Shining★Sparkling” but i was not up for it 😭.

Anyway thank you wonderlands x showtime for another banger
