Trivia

Proof of the existence is the SECTOR B boss song of beatmania IIDX 20 tricoro's Ω-ATTACK, and the final song of the event itself.
Proof of the existence marks the first Naoyuki Sato song to be rated a 12 on Single ANOTHER difficulty in beatmania IIDX.
Similar to Plan 8, the design of the boss in Proof of the existence's overlays is a blue-coloured joker mech surrendered by blue crystals.
- When you miss a note, the joker mech reveals itself as a girl and a boy, both dressed in white and blue, who attack the Q-pro avatar with the aforementioned crystals.
  - The girl joker is named Lupica, while the boy joker is named Repika. Lupica is manipulated by Repika, but she is set free from his influence in the final cutscene of Ω-ATTACK. Lupica joins Q-pro's side, while Repika retreats.
Proof of the existence was added to jubeat saucer as part of the Café de Tran unlock system. It is the 4th unlockable song for that game.
In the U.S./EU iTunes version of the beatmania IIDX 20 tricoro ORIGINAL SOUNDTRACK Vol.1 album, the last word in Proof of the existence is now spelled with an upper-case E, and the artist name is now credited to Nekomata_Master+.
