This paper toy is a chibi Chosokabe Motochika, a character that has appeared in the video game series Sengoku BASARA, but only as a playable character after the first Sengoku BASARA, the papercraft created by smilerobinson.
Chosokabe Motochika is depicted as a pirate leader who likes adventuring. Rather than conquering the land, he prefers exploring through islands, searching for treasures. He also cares much about his underlings that they are becoming affectionate of their leader, and so he is called Aniki by them.
Motochika was a pirate leader and the lord of the island Shikoku. He strongly opposed anyone who tried to conquer his lands. He also had various fights and a rivalry with Motonari Mori and partnership with Mori Ranmaru.
After Toyotomi Hideyoshi, the conqueror of the land, was killed by Tokugawa Ieyasu, Shikoku was attacked by the latter. Ieyasu succesfully conquered the island and Motochika had to flee. Motonari adviced Motochika to join forces with Ishida Mitsunari, the biggest enemy of Ieyasu. Motochika took this advice and joined with Mitsunari. [Source: wikia]
