This cube craft paper model is the Katakura Kojuro, based on the video game Sengoku Basara. This papercraftis designed by blackignus. Katakura Kojūrō is a loyal retainer of Date Masamune, but also appears as a brotherly and mentor-like figure for the One-Eyed Dragon. Modeled after a typical yakuza-style gangster from the movies, his manner of speech, attitude towards his subordinates and even his secondary attack string clearly reflect this inspiration.
Kojuurou values honor and loyalty above everything else: he was ready to be executed for the "sin" of turning his sword against his master. Kojuurou has been hinted to be stronger than his master various times, and possibly he himself knows this; but he has unwavering faith in Masamune, despite the latter's young age and recklessness. In the One-Eyed Dragon he sees the future leader of Japan, and is determined to bring his master's ambition to fulfillment.
Sengoku Basara is a series of video games developed and published by Capcom, as well as a bigger media franchise based on it, including two anime series and an animated film. Its story is very loosely based around the many real characters and events of the titular Sengoku era in the history of feudal Japan.
