Rei Ryghts, known as Rei Kiseijou (キセイジョウ・レイ, Kiseijou Rei) in the Japanese version, is the Console Patron Unit (CPU) of the fallen nation once known as Tari in the Ultra Dimension's Gamindustri. She represents the Atari 2600. Her personality undergoes an extreme change between her human and goddess forms, going from a meek, apologetic, and fearful woman to a megalomaniacal despot.

- Her Japanese name is a pun based on the pronunciation of the term 規制条例 (ki-sei-jou-rei), which means "regulation act".
- Her Japanese name, when written in Western order (Rei Kiseijou), has the initials "R.K", which correspond to those of Raymond Kassar, CEO of Atari at the time of the Great Video Game Crash of 1983.
- Her English localization name is a play on "rewrites."
- Rei is the only goddess to not have a known CPU name for her HDD. In the Colosseum, she is simply labeled as the CPU of Chaos.
- Rei Ryghts is likely to be the most powerful character to appear in the Hyperdimension Neptunia franchise. As a CPU, her Ultradimension self boasts the power to destroy entire worlds (something that not even Hyperdimension's Deity of Sin is capable of accomplishing without external measures to increase her power), and can effortlessly transfer any amount of her own power (and memories) to her Hyperdimension counterpart. After several power boosts, by the end of Victory her Hyperdimension self can even breach the fabric of time and space and create portals to other dimensions (as demonstrated when she sent Neptune to the Ultradimension) and generate a potentially limitless number of fake CPU clones that are stated to have strength that is nearly equal to that of the real Goddesses. She can do all of this without the supplemental energy gained from Shares.
- The surreal and strange "illustrations" that Rei shows to the goddesses while explaining her history were drawn by her Japanese voice actress, Yū Kobayashi.
