Shiteyan'yo

Shiteyan'yo (シテヤンヨ) is derivative of Hatsune Miku created by the Pixiv's user リューセイ (Ryūsei), also known as puzzle157xxx. The character basically is a Miku's head with legs as twintails.

History
Shiteyan'yo born of the idea of creativity of imagining Miku's twintails in the form of legs (in similar way how Tako Luka was conceptualized). Being as original as disturbing, the character become a popular meme in Pixiv, receiving numerous fanarts and parodies.

Like Ca Calne, although the character isn't recognized officially by Crypton, she has appeared in the Project Diva games in some of the backgrounds and skins.
