OK, seriously, the 3 pictures look all the same.
a. One quick shot from [The Tale of The Princess Kaguya]
b. BS28-X07 (Preview) Ultimate-Kaguya
c. BS25-X05 The LightHero LunaArk-Kaguya
Though the face are not the same, but the crown (or just a type of acssesories?) are similar.
The Tale of The Princess Kaguya -- Created in 2005, Movie show in 2013 (Japan), 2014 (Korea, Taiwan, France, Hong Kong)
LunaArk-Kaguya -- 2011
Ultimate-Kaguya -- 2014
Maybe they are copying each other, but Kaguya is a Japanese folktale that called "Taketori Monogatari", which means The Tale of the Bamboo Cutter.
Beautiful story. ^ ^
