Age: 15 (debut), 25 (end) Birthday: May 8, 1993 Birthplace: Saitama-ken, Japan Iwase is an intelligent girl who was a classmate of Mashiro and Takagi during Junior High. Iwase is an academic achiever in school. She's difficult to get along with due to her strict and high-standard nature. She leads a rather lonely life however, this doesn't bother her as she's always focused on her studies. In her world, she only respects people that rivals her ranking in school. When she appeares with Miyoshi Kaya at Takagi's house after his suspension, she reveals that she liked him. She took notice of Takagi during their middle school days as the only person that managed to out-rank and out-score her in academic performance. For her, giving out a simple hand-shake was a huge deal, as it meant a physical sign of respect and even going out together. However, she was so subtle to Takagi that she entirely missed the chance to properly convey her feelings. Her occasional mouth of challenge to Takagi only suggested to him to maintain this one-sided rivalry, but in reality, she was encouraging him in her subtle romantic intentions. Things started to change when she realized Takagi dropped in his school ranking and even stopped caring about his scores. When he was pressed to choose between her and Miyoshi, Takagi made it clear he's focused on being a mangaka more than romance. When Iwase tells Takagi to not pursue his ambitions and instead continue their academic rivalry she, to her surprise, was rejected by him. She reappears in chapter 60 as a student at To-oh University and novel writer. Iwase worked in publishing to prove her line of literary works are superior to Takagi, but unfortunately, it was another unofficial rivalry that he didn't realize until she pointed it out later. Iwase however, still she sees Takagi as a rival and decides to write stories for Shonen Jump to see if she can beat him at his own game. Her editor is Hattori, who worked with Takagi and Mashiro. She later becomes the writer for Eiji's new manga +Natural. She also teams up with Eiji for a collaboration in Crow for a few chapters. After Hattori returns as Takagi and Mashiro's editor, her new editor is Miura. Her writing and plot are praised for being very well made.
Age: 23 (debut), 31 (end) Birthday: May 14, 1987 Miura is the second editor for Ashirogi Muto. He is very enthusiastic and excited, and sometimes not a hard enough editor for the boys. After Detective Trap was canceled, he pushed Mashiro and Takagi to work on a gag manga.
Age: 45 (debut), 55 (end) Birthday: February 22, 1963 Editor-in-Chief of Weekly Jump. He tends to behave indifferently or even coldly but it's all for Jump's authors and editors to regain their spirits. He has a good eye for manga and believes it's most important for a manga to be interesting. He's not afraid to make a gamble in order to make the magazine better, but will not put authors' lives at risk. He knew Saikou's uncle, Kawaguchi Taro, since he was the Assistant Editor-in-Chief at the time Kawaguchi Taro had to quit.
Elizabeth resembles a giant white duck or a giant penguin and is Katsura's companion. Elizabeth was a present from Tatsuma Sakamoto, who presumably picked it up on his travels around space. Although many people consider Elizabeth to be insane and extraneous, Katsura has named the ambiguous avian "Elizabeth" and dotes on it. Once in episode 18 Shinpachi purchased a doll named as Space Alien Stefan (宇宙怪�ステファン) to which looks perfectly similar to Elizabeth. Elizabeth is something of a painter, and is surprisingly dexterous. Also, Elizabeth resorts to using signboards to "communicate," as well as an occasional means of attack. Elizabeth is also a skilled fighter, able to use signboards to fight off swordsmen. Although the true identity of Elizabeth is uncertain, it appears to be a man wearing a duck costume. In its first appearance, hairy legs are seen underneath her sheet and the body of a humanoid with glowing eyes is revealed as her mouth is opened just as it fell during another battle between Gintoki and Katsura. Although Katsura seems shocked at what she really is, she has subsequently remained by his side. Episode 50 implies that the person inside Elizabeth is most likely the director (Gintoki was interrupted before he can finish being cut off at "Kanto-" ("Direc-"). Most of the characters seem to ignore this, or at least do not give it much thought, given at the episode was completely filler. Moreover, the next time the inside of Elizabeth is shown, it reverts to the glowing eyes. When Shinpachi boards Takasugi's ship in order to rescue Kagura, a bazooka is seen coming out of Elizabeth's mouth when she blasts the ship to distract everyone from Shinpachi. Because of this, Shinpachi refers to her as Elizabeth-senpai. Elizabeth's birthday is September 7. "Her" height is 180 centimeters, and "she" weighs 123 kilograms. (Source: Wikipedia)
