This cube craft paper model is the Natasha, based on the anime / mange series “Saint Saiya“. The cube paper toy is designed by blackignus. The Natasha is one of Mitsumasa Kido’s women and late mother of Cygnus Hyoga. After dying in a shipwreck, her remains were preserved intact by the gelid waters of the Siberian seas. She’s also alternatively known, both in the manga and anime adaptation as Hyoga’s Mama.
Kurumada later introduced a character of the same name in the short story arc dedicated to Hyōga in the thirteenth volume of the manga, sister to Alexer, leader of the Blue Warriors.
