Nickname for Gintama (a manga) character, Katsura Kotaro. Based off of Japanese historical figure Katsura Kogoro. An overly serious character who is trying to rid Earth of aliens, he works steadily to avoid capture by the anti- terrorist squad the Shinsengumi. He is an old friend of main character Gintoki Sakata and often tries to recruit him for the terrorist squad. He has a weird space pet that is a little like a duck named Elizabeth who most believe to be an old man in a duck costume, although Katsura never sees anything wrong with it. Dislikes being called Zura. When being called Zura he usually exclaims 'It's not Zura, it's Katsura!' There are several different hilarious variations of the catchphrase.
It's not Zura, it's Pine Tree!
