Caelus is a minor character and a former Planeptune CPU who appears in Hyperdimension Neptunia mk2 and Hyperdimension Neptunia Re;Birth 2: Sisters Generation.

Hyperdimension Neptunia mk2[edit | edit source]

In the true ending, the party must find Caelus to find out how to defeat the Deity of Sin. Caelus tells the party that she and three other CPUs fought Arfoire, but did not actually defeat her, only managing to temporarily weaken her and sacrificed themselves to seal Arfoire away and as a result, she only exists as a soul with her physical body gone.

Trivia[edit | edit source]

  • Her name comes from the Roman sky god Caelus (Uranus or Ouranos in Greek Mythology)
  • Sega codenamed their projects after the planets. However, Project Uranus' development is unknown and is possible that Sega never used the codename.
  • The player unlocks the trophy "Caelus" once meeting the former CPU.
