TsuKanae

TsuKanae is the Femslash ship between Kanae Kocho and Tomioka Tsutako from the Demon Slayer fandom.

Canon
Tsutako and Kanae have never met in the series. But both of them do have some things in common. They are both older sisters of two current Hashira, those being Giyu Tomioka and Shinobu Kocho. Both of their deaths devastated their younger siblings and both of them were viewed as very kind people to their relatives along with a few others. Both of them took very good care of their loved ones. Tsutako had Giyu live with her after their parents died from an illness. Kanae became a Hashira and bought a mansion for not only her and her sister, but she also adopted other individuals who had lost their families. Those being Aoi Kanzaki, Kiyo Terauchi, Naho Takada and Sumi Nakahara. She and Shinobu also adopted Kanao who was abused by her parents and sold into slavery.

Both Kanae and Tsutako’s deaths had a huge toll on their siblings. Tsutako’s death greatly saddened Tomioka and he grew extremely pessimistic after her death. Shinobu was extremely devastated and she grew a strong hatred for demons and was almost constantly angered state after her sister’s death, along with the deaths of few other people she cared about. Lastly, both of their family members wear something in order to remember both of their elder sisters. Shinobu wears the exact same Haori her sister wore when she was alive and Giyu had his haori designed so that half of it matches the Kimono her sister wore while she was alive.

So while two may not have met. Both of them had major impacts on their relatives' lives. Both of them are very missed by their relatives and thrive to continue living for them. The lost of these two is likely what lead to their relatives to become the people they are now. Shinobu tries her best to maintain the smile Kanae always loved and also wants to be that same motherly figure that the others at the Butterfly Mansion viewed her. And Giyu also has great respect for her sister to a point where he even had his Haori designed just so he could have something left to remember her.

Overall, Kanae and Tsutako have never interacted. But the two are quite similar in personality and character. And both of them continue to watch over their remaining family from above and cheer them on as they make their way into battle.

Fanon
TsuKanae is a rarepair among the fandom. Them not interacting may be a reason why. However this is currently one of Tsutako's only ships.

The ship can be overshadowed by Kanae's more popular ship (SaneKana). But aspite being a rarepair, it is still supported by some fans. A lot of fans tend to ship them together because they believe the two would grow a close bond if they met and eventually become lovers.

But Tsutako canonically had a fiance. But people don't necessarily hold that against this ship since Tsutako's fiance was never shown onscreen. Also the gender of her fiance remained unrevealed as well. While many would assume her fiance was a male. Some believe that there was a possibility that Tsutako's fiance was a female. It is unknown if Tsutako is straight or lesbian but some fans believe Kanae is Pansexual. Gacha life users tend to ship the two quite often.

The ship currently has 10 works on Ao3.
