Fate

The Hinode family well known for sun breathing. By miracle this family has survived long enough to have this generation; sun breathing was passed down for generations, well feared by demons. And well targeted, they have had to keep a close eye on anyone pregnant in this family, because they would be targeted and likely killed by Muzan or some of the other demons.

Tanjiro who just figured out that demons actually exist after his sister Nezuko turns into one after a tragic event of their families death, has started out on a journey to find a way to make Nezuko a human again.

Hinode Y/n one of the final descendants of the Hinode line along with her older sister Hinode Hina. They have been using Sun breathing for some time now, Hina who has just joined the ranks of Hashira, while your at Kinoto. You of course can't become a Hashira since your sister has taken the spot.

Of course she'll introduce you to the other Hashira. Maybe you can make some friends, meet the main protagonist Tanjiro.

Find love?

It's all up to fate.

I know that Fate has brought you to me...
