Additional Information





Kagamine Rin (derived)

Larval Rin is a derivative of Vocaloid Kagamine Rin created by the Pixiv's user Mossan. The character is a heavily deformed Rin head on a pair of skinny legs.



  • Mossan submitted a chart showing the different "evolutions" of Larval Rin. There are 3 stages in the development and growing of the creature.
    • The first stage is the actual Larval Rin.
    • The second stage is the actual Kagamine Rin. The description in the original illustrations says that Larval Rin reach this stage at lv14.
    • The third and final stage is a Kagamine Rin with a growing giant appendage, so big that Rin's trunk is a bit displaced or tilted . This one seems to be horrible, as in the chart appears censored.


Due her resemblance and her serious and disturbing expression, it is normally depicted along or associated with Shiteyan'yo (and occasionally with Tako Luka), causing havoc or annoying other Vocaloid characters.


Created by Mossan, Larval Rin seems to conceptualized as some sort of pre-evolution or a previous stage of development for Rin.[1][2] Being as original as disturbing, the character become a popular meme in Pixiv, receiving numerous fanarts and parodies.

  • Larval Rin is considered along Calne Ca and Shiteyan'yo into the group of the Nightmare Fuel Vocaloid Mascots. It isn't rare that they are depicted together in videos and fanarts (specially along Shiteyan'yo due the physical resemblance).
  • There exists a "cute" representation of Larval Rin, with a chubby body and big rounded eyes instead the disturbing realistic and serious look.
