Nyaa-tan is the main character of Etotama’s anime.
Suitable with a cute cat personality, Nyaa-tan is an airhead character but at the same time is cheerful and playful.
She aimed to be one of the 12 Chinese Zodiac and in order to do so she has to battle against other Zodiac girls and get 12 seals to gain a spot.
Nyaa-tan here is made by Warraty, a Japanese pepakura designer. Warraty made two templates version , hard and normal. Although I do not see any differences in between those two templates..
I think he probably meant one with lines and the other is has none.
