TanShino

TanShino is the het ship between Shinobu Kocho and Tanjiro Kamado from the Demon Slayer fandom.

Canon
Tanjiro and Shinobu meet each other for the first time in the forest after  Shinobu attempted to kill nezuko, but Giyu prevented her from doing that. In the process she tells him that it is dangerous to be so close to a demon. Later on, during the Hashira's trial, In this she is the only one trying to hear Tanjiro’s side of the story. While Tanjiro desperately tries to explain to them that Nezuko has not and will not hurt any humans. Shinobu had a sad expression on her face.

She does later come to care about Tanjiro and Nezuko and is seen to be visibly concerned about the both of them, even letting them rest at her estate so that they can recover from their injuries. When Tanjiro was told about the death of Shinobu, he was visibly sad due to this since he cared about his friend.

During Tanjiro’s rehabilitation period Shinobu helps him train, and even though she initially does not understand his drive to protect his demon sister, Shinobu does grow to care for him. She trained Tanjiro, Zenitsu and Inosuke,  and seems to be the closest or, is at least the least irrated with Tanjiro, since he took his training seriously from the start, which Zenitsu and Inosuke did not.

Fanon
TanShino is a rare pair in the fandom, which is why it's mainly overshadowed by their more populair ships like GiyuShino for Shinobu and ZenTan, TanKana for Tanjiro. It right now has around 38 fics on AO3.

Their are people who this more a friendship than as a romantic ship.
