You're My Rain and I'm Your Sunshine! (Tomioka Giyu x Y/N Kamado)

Y/N Kamado, the eldest child of Kie Kamado and Tanjuro Kamado. She has left the house at the age of 13 to go for something urgent but never came back, her mother thinking she died but never told Tanjiro or Nezuko. Tanjuro was the only one who knew what happened and accepted her wish to become a hashira in the Demon Slayer Corps. Over the years Y/N Kamado became a pillar at the age of 16, and they call her the Ice pillar since she invented it because of the snow she had back at home. A couple of years later, she meets the new water pillar, Tomioka Giyu.
How will Y/N interact with Tomioka and how will he react towards her? How will Y/N react once she gets the new that her younger brother has become a demon slayer and her younger sister a demon?
