This papercraft is Asuma Sarutobi, a jōnin of Konohagakure's Sarutobi clan as well as a former member of the Twelve Guardian Ninja, from the manga / anime series Naruto, the paper model was created by Rexxkentrix. There is also His Chakra Blade Papercraft on the site.
Asuma was typically a laid-back individual, and did not get himself involved in things unless absolutely necessary, as seen when he decided not to help save Hinata Hyūga during her fight in the Chūnin Exams. He was a heavy smoker but despite this, he would abruptly break the habit under certain circumstances, such as when his father died, or learned that Kurenai was pregnant. Not always seeing eye to eye with his father, Asuma later came to respect his father's role as Hokage: referring to him as a great father, and was proud to have been born into the Sarutobi clan.
Despite Asuma's very blunt personality, often calling his students what they were unreservedly, a "glutton", a "loud mouth", and a "slacker", he had a very good relationship with all three. He often took them to Yakiniku Q for lunch and dinner where more often than not Chōji would eat too much and Asuma had to pay more and apologise emphatically to the owner. To help them overcome their underachieving natures, he attempted to use bribery and outright trickery to manipulate them into doing what he wanted. This was seen most with Chōji, who Asuma was frequently able to entice into action with the promise of food and even Shikamaru whom he had to use games like shōgi on to assess his skill level. Out of his students, Asuma spent the most time with and was closest to Shikamaru. Asuma and Shikamaru often played shōgi or Go in their free time, though Asuma was never able to beat Shikamaru. It was Asuma who first discovered that the lazy Shikamaru was actually a genius, with an I.Q. over 200.
Throughout the series it had been heavily hinted that Asuma was romantically involved with fellow jōnin Kurenai Yūhi, having been close to her since childhood. The two appeared together in most of their scenes, and the other characters made it a point to note this fact on several occasions. When Kakashi Hatake found the two together at a dumpling shop, Kakashi asked if they were on a date, to which Asuma responded by quickly changing the subject. In a flashback, Asuma was shown buying flowers for a person he refused to name, though Ino asked that he say hello to Kurenai for her anyway, to which Asuma nervously asked how she knew about it. During Asuma's battle with Hidan and Kakuzu, Kurenai was often shown wondering about his progress, appearing anxious. When she heard of his death, she fell to her knees grief stricken. She later laid flowers on his grave during his funeral. The truth of their relationship was then made clear when Kurenai revealed that she was pregnant with Asuma's child. [Source: wikia]
