After three months since introducing the prototype at Wonder Festival in August, Good Smile Company's Mika-tan blog finally revealed the finished model of Nendoroid Miku Dayo. Miku Dayo is originally the name of the human-sized character suit of Hatsune Miku modeled after the first Nendoroid Miku. The fans often affectionately called her "Dayo-san." Mika-tan's quick summary is;
(1) Sega made the ‘Project mirai’ game, featuring Nendoroid Vocaloids!
(2) A life-size Nendoroid Miku costume was made to promote the game!
(3) Everyone felt the costume didn’t quite feel like the real Miku!
(4) The costume Miku became her own character, Miku Dayo!
(5) Miku Dayo is made into a Nendoroid, completing the cycle!
