GinTsu

GinTsu is the het ship between Sakata Gintoki and Tsukuyo from the Gintama fandom.

Yoshiwara in Flames
Episode 140/Lesson 211-213

Starting out as enemies, Gintoki's and Tsukuyo's first meeting happens in the Yoshiwara in Flames Arc, when Gintoki steps in to reflect Tsukuyo's kunais that were aimed at Seita and Shinpachi. His entrance to the fight doesn't work as smoothly and main-character-like as he planned to, as one of Tsukuyo's kunais lands straight in his forehead and he's bleeding pretty badly. His instant reaction to that is denying the fact that he got stabbed to not be embarrassed in front of the enemy. Gintoki and Shinpachi argue about what happened while Tsukuyo, Kagura and the Hyakka just stand by and watch them. It gets to a point where he is too embarrassed to face his enemies Tsukuyo and the Hyakka. At that point Tsukuyo steps in and helps him, saying he knocked down every of her attacks even though she knows it's a lie. Gintoki is surprised about this and says she's a nice girl for going along with it. He faces her for the first time and downplays her attack and describes her kunais as kunais going for a leisurely stroll. Furthermore, Gintoki resorts to flirting with her, suggesting to stab her with something better, but he is interrupted when he notices that he has a Kunai stuck in his hand as well. In the manga you can even see that one of Tsukuyo's kunai is sticking on his backside when he turns around again.

Gintoki asks Tsukuyo to lend him her kiseru to light up the remaining bombs and to make sure they make a promise to each other that they will return if everyone survives to the end.

3Z Ginpachi Sensei Novel 6: Funky Monkey Teachers
Lecture 1 "Don’t expect ot understand everything after just one day of experience. Eh? No one said anything about understanding? Then.., I’m sorry."

Tsukuyo appears for the first time as the new teacher transferred from Yoshiwara Commercial in the 6th novel of the Class 3-Z Ginpachi-sensei series. Tsukuyo is in charge of health and physical education. In one of her First Aid simulation classes, Ginpachi acts as the wounded person much to the surprise of the student. It is mentioned that he was supposed to show up later in the book and not in her class (p. 49).

Lecture 3 “Playing Doctor as adults is not the same as playing Doctor as children”

Ginpachi is using a shortcut through the back gate behind the gym of Gintama High to get to class. On his way, he spots a suspicious person reaching for something white stuck in a tree. Ginpachi runs to confront the man, but he escapes behind the gym from where Ginpachi came from and runs into Tsukuyo, who is ordered by Ginpachi to "Get that pervert!". She was using the same shortcut as Ginpachi at almost the same time. Tsukuyo knocks the man out and Ginpachi comes over. Shortly after, they realize it was actually the doctor who was supposed to do health checkups on the students. Ginpachi tries to shift the blame on Tsukuyo, saying she should go to the principals office to confess her crime. He will come with her as a collegial/friendship support and to make sure her punishement will be as light as possible. She throws two kunai into the back of his head and he complains that she should use chalk or something because of the teacher setting they are in. But she replies that she doesn't care. They argue for a bit and Ginpachi concludes (in a soft voice) that it's seven to three parts her fault too. But he actually means that she has the biggest fault and as a reply to that, she pinned him to the gyms wall with countless kunai, to which he says the exact same thing as in a similar scene from Courtesan of a Nation Arc: "… un, ochitsuite, tsukkī" (Calm down, Tsukki). He suggests that they should work together on a plan to solve this problem.

Fanon
According to pixiv stats, GinTsu is the third most popular hetship in Gintama fandom.

When searching for Gintama and adding Gintoki's first kanji on japanese yahoo, Gintsu is the 4th and 8th remmonded search suggestion. If you type in Gintoki's full name after "Gintama", it also is the 4th result. Typing in Gintoki's full name only, suggests "GintokiTsukuyo" as the second search suggestion.

Chemistry between them could already be seen in her introduction arc (Yoshiwara in Flames). However, a lot of fans really started to ship this pairing with the publication of Red Spider Arc

Trivia

 * Gintoki and Tsukuyo are two of the few characters in the Gintama casts who's names are based on mythology:
 * Gintoki - According to Hideaki Sorachi, Gintoki's name was based on Sakata Kintoki, also known as Kintaro, from a famous folk tale set in the Heian Period. Kintaro became friends with the animals that lived on the mountain where he was raised and was even capable of battling with them. After certain events, he became a samurai and eventually went under the name Sakata Kintoki (坂田公時). Sorachi-sensei, in one of the question corners, explains this and doesn't intend on making Gin-san a descendant of Kintaro. His robot counterpart actually does take the name of Sakata Kintoki.
 * Tsukuyo - Her name and character is based on a kami from shintou mythology. Tsukuyomi, sometimes called Tsukuyomi-no-Mikoto (the great God Tsukuyomi), is rendered as 月読尊, or simply 月読 in Kanji. This name directly translates to “moon-reading,” a popular practice in the noble courts of pre-modern Japan where parties would stay up all night moon-gazing and reading poetry. An alternate Kanji reading is tsukuyo, moon-light, and mi, watching. His personality is described as follows: Tsukuyomi is very much a match for his wife Amaterasu. Beautiful and serene, he believes in order and etiquette and enforces them whenever he can. His enforcement of such ideals extends to the point that he is willing to kill to maintain order, despite killing itself being a breach of etiquette in the heavenly court. Thus, there is irony in Tsukuyomi’s strict adherence to etiquette: to enforce it, he is willing to break it. Though the moon is often regarded as beautiful and worthy of viewing, Tsukuyomi himself is seen as a negative figure in Shinto and Japanese folklore. This personality description can be projected onto Tsukuyo who, for example, also kills to maintain order in Yoshiwara.
