This paper toy is a chibi Azai Nagamasa, the daimyo of the Azai clan, husband of Oichi, brother-in-law to Oda Nobunaga and an ally of Asakura Yoshikage, based on the video game series Sengoku BASARA, the papercraft created by smilerobinson.
A former ally of Oda Nobunaga, now rebelling against him. He is a man fighting for justice and vows to destroy anybody who creates chaos, namely Nobunaga. Wields a long sword and a folding buckler. His fighting style and mannerism are similar to that of a typical superhero, primarily the Metal Hero Series. He's also often seen roughly telling Oichi to shut up or stop crying, only to shyly declare his love, making him a male tsundere. He is playable in Sengoku Basara 2 Heroes.
His story revolves around ridding Japan of the chaos, preferably Nobunaga, and his relationship with Oichi which started out with love, then turn to hatred and eventually leads back to loving her again. Nagamasa's story can be looked at a tokusatsu point-of-view due to certain elements of the genre present. He is the husband of Oichi. He is confirmed to be dead in Sengoku BASARA 3. [Source: wikia]
