TsukiSachi

TsukiSachi is the femslash ship between Tsukuyo and Sarutobi Ayame from the Gintama fandom.

Canon
Tsukuyo and Sarutobi often argue with each other. This is less because of the fact that they sometimes see each other as love rivals, but rather because of their almost polar-opposite personalities. Tsukuyo is always calm, serious and rarely talks. Unlike Sarutobi, who is usually loud and much more childish. Sarutobi likes to call Tsukuyo "Tsukki".

Tsukuyo and Sarutobi first met in chapter 267 of the Character Poll Arc. At first they do not seem to get along as Sarutobi thinks Tsukuyo is too serious and a rival in love as both are interested in the same man. Despite this they hit it off really well and start regularly hanging out developing a really good friendship. They are usually paired together in comedy arcs with mentions of their off screen meetings. Sarutobi supports Tsukuyo and pushes her out of her shell with their friendly rivalry bickering even though Tsukuyo does not see her as a rival in the first place.

In the Dekobokko Arc, a gender bent Gintoki and Hijikata try to score boys on the bridge, but they then come over the gender bent version of Tsukuyo and Sarutobi who had just destroyed a number of surveillance cameras. Later, other characters regroup in an alleyway to discuss about the cameras and other matters when Tsukuyo, the Hyakka and Sarutobi reveal that they had already destroyed all of the camera and managed to capture all the Dekobokko members as well. Tsukuyo, Sarutobi and other originally female characters soon infiltrate the sewers that lead to the Dekobokko HQ.

In Episode 216, Tsukuyo encounters some kids asking her about her job at Yoshiwara which she refuses to answer any questions to. That's when Sarutobi, dressed up as a pre-schooler arrives and requests Tsukuyo to teach her and the kids how to 'whip a man in a way that brings pleasure'. Tsukuyo refuses and replies that 'that'll be the last thing I would teach you.' Sarutobi then asks Tsukuyo whether she'll be responsible if her relationship with a guy goes wrong. Tsukuyo thinks that it's better if she teaches the crowd now before the time comes and starts to point places on a 'Patriot', which scares the kids away. Tsukuyo is later seen crying with the 'Patriot' beside an angry Sarutobi shouting at her to tell her the secret techniques of Yoshiwara. As an attempt to invite the children inside the Patriot factory, TsukiSachi pretends to be fascinated at the entrance. The two then steps in the factory, leading them to get shot by Hijikata upon enetering. At the conveyor belt of the factory, TsukiSachi along with a few other characters start to fix the broken chief, the two are soon try to encourage the chief by holding a flag that writes: Do your best! Become the best factory chief in Japan! And drops on the floor. Later on, the conveyor belt arrives at a scene where the chief is being scoffed for his dreams, Tsukuyo and Sa-chan can be heard.

In Gintama's 2nd movie, 'Gintama: The Movie: The Final Chapter: Be Forever Yorozuya', Tsukuyo stops Sarutobi from kissing Gintoki by chopping her head off.

Fanon
TsukiSachi is the main wlw ship in the fandom for Tsukuyo and Sarutobi as the other two members of the Diamond Perfume are shipped with each other more often instead. Their clashing personalities, both being ninjas and contrasting designs is what draws fans to this ship.

Romantic
In fan material of this ship, Sarutobi who is a huge masochist is often seen hugging or bowing down to Tsukuyo. She'll often appear with heart eyes and a big smile. Tsukuyo on the other hand will often be the hard-to-get, showing little or no emotion but is actually also madly in love.

Friendship
As both Tsukuyo and Sarutobi have crushes on Gintoki, more people ship them platonically than romantically. People like to think of them as love rivals or good friends who fight often with each other or with enemies. Fan art is usually quite seductive because Sarutobu is a masochist and Tsukuyo is deemed as very attractive to many fans.
