Rin's appends are "power," "warm," and "sweet" while Len's appends are "power," "cold," and "serious." An update, Kagamine Rin/Len V4X, was released for Vocaloid 4 on December 24th, 2015.
This package contains six Japanese vocals, three for Rin and three for Len. Rin's vocals are "Power EVEC," "Warm" and "Sweet" while Len's are "Power EVEC," "Cold" and "Serious." EVEC is a new system developed for Piapro Studios which allows delicate changes to how phonetic sounds sound.
After seeing many works that depict their relationships differently, Crypton announced on a magazine interview that those would meet their ideal.
Crypton's final announcement was they are neither siblings nor lovers During Vocaloid 2 Append production, Wataru Sasaki described them as having one soul between the two of them. For their appends, Wataru wanted them to have a sense of transparency with their design.
As a result, he and Ryuto were not referenced in the development of VY2.
In 2010 after Hatsune Miku Append was released for Hatsune Miku, Kagamine Rin & Len Append was released for Rin & Len.
Asami Shimoda noted that she often received comments from Vocaloid fans that Rin's voice echoes within their head and makes them feel dizzy, while Len's higher ranges were not favoured by those not fond of the pair entirely.
Despite being released as a masculine character, during the development of VY2, the vocals of Ryuto or Len were not classified as "masculine vocals" and were not considered capable of holding a low masculine tones because of it.
But overall, it was very good to watch and I highly recommend it for those of you who enjoy something aside from mainstream anime and don't mind nudity, action, explosions, etc. “ Mnemosyne”, also known as “ Mnemosyne: Mnemosyne no Musumetachi”, is a six episode series containing a mix of supernatural, science fiction and horror elements.
What will no doubt strike most viewers about this series are its explicit horror and sexually tinted scenes.
Considering these horror and sex scenes, as well as the themes behind them, “ Menomosyne” is only suitable for mature viewers.
The story surrounds a woman named Rin Asogi who runs a consulting agency with her friend Mimi and pet dog Genta.
The thing is, they are both immortal from a plant called Yggdrasil which releases spores that if entered into a woman, makes them immortal and they can live for practically forever.
