Originally, four more vocals were planned after Tone Rion as part of the Vocaloidol group. It is unclear whether or not Nemu is one of the originally planned vocals.

Package details as noted:
Though both Tone Rion and Nemu share the same provider, the Nemu product is intended to be a faithful recreation of the provider in contrast to Tone Rion and was recorded in her normal talking voice.
Also included is over 130 recordings of the provider.
Vocal traits as noted:
Produces more realistic results than Tone Rion.
She has a larger vocal range than Tone Rion.
Nemu's vocal sounds more mature than Tone Rion's vocal and is intended to be more adult-like.
The vocal has more power in its tone than Tone Rion.
Software issues as noted:
Though treated as different singers, there is sometimes problems with separating Nemu and Rion from each other. When singing something simple that doesn't challenge either vocal, they can often sound very alike and their core very similar sounding. This is simply because they share the same provider for their voices.
Nemu leaves Rion behind when their vocals are pushed to their limits, as Nemu's vocal performance can go further then Rion's vocal performance overall.
Nemu was recorded with the new VOCALOID4 recording style, which allowed more vocal traits to be recorded, while Tone Rion was recorded with the old method style used until VOCALOID3. The new recording style sacrifices ease of use in order to capture more vocal traits. The result is if the pair are compared to vocls of their same type, Nemu in theory will sound more distinct then Rion does.
In total two packages offer the equivalent together of 2 additional voicebanks achievable via XSY. The total tone variation offered by the package comes to a theoretical 4 voicebanks in total.
