Mikudayō (ミクダヨー) is a human-size Nendoroid costume created by SEGA. She is derived from the VOCALOID2 Hatsune Miku.
The term "Derivative" is used here to describe a fanmade Vocaloid character that is based on an already existing character.
Mikudayō first appeared at Tokyo Game Show 2011 as a sales promotion character for the game Hatsune Miku and Future Stars Project mirai by SEGA. The overall design was based on Nendoroid Miku, but the details were rough and clumsy. Her unbalanced big head, dull eyes, chubby cheeks, large rubber rain boots and threatening forward tilting posture with awkward movements made a topic on a Futaba Channel bulletin board and the contributors gave this bodysuit the name Mikudayō, which means I'm Miku or She's Miku.
In April 2012 the SEGA staff used this fanmade nickname on a Nicocast program and Mikudayō was widely recognized as the de facto official name for this character.
On September 24, 2012, SEGA, Good Smile company and Crypton jointly registered Mikudayō and she was added to the official fanmade characters of Crypton.
A Nendoroid model was released in March 2013.
- This clumsy Miku bodysuit caught Vocaloid fans and led to other Mikudayō-like Vocaloid character illustrations and MMD models. They are collectively called Dayō series.
- Common fan description is Mikudayō has a bad personality. In many fanarts and Nicovideo clips she often speaks nasty words and sometimes attacks people.
