GinSachi

GinSachi is the het ship between Sakata Gintoki and Sarutobi Ayame from the Gintama fandom.

Canon
Sarutobi is introduced in chapter 40 of the manga and episode 22 of the anime. During one of her assassin missions she falls through the roof and lands on a sleeping Gintoki. This makes the Yorozuya trio believe that Gintoki has slept with her, she uses this to her advantage pretending that is indeed what happened so she can use Gintoki to finish her mission. Afterwards Sarutobi comes clean but Gintoki already figured out the truth by this point. He tells her next time she needs help she should just come to Yorozuya normally because he is willing to assist her on his own. This really resonated with Sarutobi and made her develop a crush on Gintoki. Her crush also awakened her masochist side which lead to her stalking of Gintoki.

Gintoki is usually quite mean to Sachan and calls her various bad names like 'perverted' and 'dirty woman'. This however does the opposite affect he wanted due to Sarutobi's masochism. Despite this, Gin still cares about her and has helped her occasionally like in the Glasses Arc, which Sa-chan values deeply.

There are a few long-running gags in the series featuring GinSachi. As a stalker, Sa-chan tries to take a peak at Gin whenever possible and has hidden in many weird and peculiar places in order to do so. She has appeared in the Yorozuya household many times. Sometimes in mirrors, cabnets, a TV and many more places. The two other Yorozuya members have even gotten used to her usual stalking, Gin as well. Outdoors, she continues her stalking and has appeared in bushes and many other odd areas as well. Unfortunately for her though, Gintoki doesn't appreciate this and usually throws items at her.

Another gag of theirs is Sarutobi's bad eyesight. When Sarutobi loses her glasses, she sees many objects as Gin. In these moments, Gintoki surprisingly turns into more of a straight man character and is seen sighing in disappointment.

Fanon
GinSachi does not get as much attention as Gintoki's other ships despite Sarutobi being a major recurring character in the series with a lot of screen time. This might be due to some viewers finding Sarutobi's obsession with Gin as off-putting. Another reason may be because of Sarutobi's popularity among fans. Compared to other characters with whom Gintoki is usually shipped with, Sarutobi is not as popular.
