I've been waiting a long time for this song. I picked up Project Sekai in the first place because I saw the all Vocaloid version of Mr. Showtime on Hitoshizuku x Yama's channel and loved it. Once I found out that this song was going to be in the game, I was very excited.
My original goal was to get a Hard FC when this song dropped. However, I've leveled up a little since then and was able to get a lucky Expert FC. Good times. Maybe I'll be able to get an Expert FC on Mr. Showtime or Vampire's ∞ pathoS when they drop in March.
