You’re Sanemi Shinazugawa, The Wind Hashira. (female)

Sanemi’s the oldest of her 6 other siblings, Genya, Sumi, Teiko, Hiroshi, Shuya and Koto Shinazugawa. Sanemi and the other Hashira are in a poly relationship together.

However, now all that were left was Genya and Sanemi due to their mother turning into a demon and killing them all but Genya.

It was just after a Hashira meeting, Sanemi was drinking coffee like always, Tengen was bragging to Rengoku how flashy he was, Obanai and Shinobu was talking shit about Giyu and he was just stoic taking it completely fine and Mitsuri was trying to get Obanai and Shinobu to stop.

Genya, Sanemi's younger brother, suddenly ran over, Tanjiro's little demon sister, Nezuko, running behind him as she wanted to play tag.

Genya jumped on Sanemi's back, clinging onto her like a koala to a tree, Sanemi managed to keep hold of her coffee mug.

Genya: ”GET THIS THING AWAY FROM ME, PLEASE NEMI!”

Nezuko was beside them now, Tanjiro ran over and picked up his demon sister and gave Sanemi and Genya an apologetic smile, Sanemi looking as if she was contemplating life as she drank her coffee while her brother clung to her.

All the Hashira stopped what they were doing, looking at Sanemi with a look of shock, why was she just letting this happen? Usually she would get pissed and scream but not with Genya, did they have some kind of relation? They both had the same last name.

Mitsuri found this adorable, Obanai and Shinobu was shocked, Giyu was stoic, Tengen was thinking this was flashy, Gyomei and Muichiro was not paying attention, Gyomei was blind and Muichiro was already forgetting what was happening.

Genya stayed on your back, Tanjiro was about to break the silence until Zenitsu ran away from Inosuke screaming... until he saw Nezuko to which now Nezuko ran away from Zenitsu and broke out of Tanjiro's grip making Zenitsu, Inosuke, Nezuko and Tanjiro run away and after eachother. Genya stayed on Sanemi's back.
