Tone Rion VOCALOID3 VOCALOID4 | Songs Albums Notable Originals

Tone Rion (兎眠りおん) is a Japanese VOCALOID developed and distributed by the YAMAHA Corporation,[1][2] and was created in collaboration with Dear Stage (Moe Japan, Co. Ltd.). She was released in December 2011 for the VOCALOID3 engine.

Rion was updated to the VOCALOID4 engine in February 2017.[3]

In December 2016, Rion's voice provider was confirmed to be Dempagumi.inc's Nemu Yumemi.[4]


According to her comic and official website, Tone Rion is 16-year-old, born on December XX, 2095. Rion works as a Vocaloidol at Dear Stage in 2111. While cleaning the back of the store, she found a 2011 memory card containing recordings of idols from the past. Amazed by them, she decided to travel back in time to 2011. When arriving, Rion went to an interview at Dear Stage, claiming to be good at singing and dancing, and saying she came from 2111 and was from Akihabara.

She is a "2D VOCALOID + 3D idol = Vocaloidol" and was the first of the Dear Stage VOCALOID "Vocaloidol" a concept of "VOCALOIDs that you can go to meet", which the vocals would come from within Moe Japan's own vocalists.


The kanji for Tone Rion's name means 兎 (bunny/rabbit) and 眠 (sleep), however the phrase itself, "兎眠" (rabbit's sleep), has no significant meaning in Japanese. Though the company does not give any account, Rion's name is believed to be a double pun on the English word Tone and the musical instrument Tenori-on produced by YAMAHA.


The design has the distinct appearance of a 'cooking' maid. However, based upon her background, the design is meant to portray an Akibamaid (秋葉原 メイド), a cosplay girl whose role is that of a waitress rather than a cook.

Her VOCALOID4 design was intended to highlight her link to Yumemi Nemu. This includes a drastic change in color scheming and her physical features such as her hair and eye colors.
