The CPU Candidate of Planeptune and sister to [[neptune (neptunia)|Neptune]]. Despite being 'born' later than Neptune, both her appearance and attitude are more mature (leading to some confusion at times). While she admires her sister and tends to spoil her, she also tries to be strict with her at times (especially when Neptune slacking off, unless she joins her in doing so).

She is friends with the other CPU Candidates [[uni (neptunia)|Uni]] (but Uni is a [[tsundere]] so she wouldn't admit that), [[rom (neptunia)|Rom]] and [[ram (neptunia)|Ram]].

In [[Choujigen Game Neptune MK2]] she had the role of the main character, but by [[Kami Jigen Game Neptune V]] she got degraded to a side character and comic relief (which she laments a few times during the course of the story, frequently breaking the 4th wall in doing so). While she frets that she lacks any defining features or traits, she eventually begins to display a talent in electronics and robotics.
