"The Wisteria Hashira has arrived!" A female attendant announced out loud. Beside her, a leg stepped into the compound, with strut of confidence and grace that dingles the bells tied to the waist. Tanjiro didn't know who the person is or what he or she looks like but he can see the demon slayers' faces brightened hearing the person's arrival.

In which, Iguro Y/n, the younger sister and the tsuguko of Iguro Obanai, the Serpent Hashira, meets the Wind Hashira, Shinazugawa Sanemi.

A pair of siblings. One male, one female. One aggressive and stubborn, the other soft-hearted and gentle. Somehow, they got along well despite the differences in personalities. He was her everything. Her friend, her playmate. Her brother. She was his best friend, listening quietly to all his words. The one person that cheered him up with the bright smile. His little sister. "𝓞𝓷𝓲𝓲-𝓬𝓱𝓪𝓷! 𝓦𝓮'𝓵𝓵 𝓪𝓵𝔀𝓪𝔂𝓼 𝓫𝓮 𝓽𝓸𝓰𝓮𝓽𝓱𝓮𝓻, 𝓻𝓲𝓰𝓱𝓽?" "𝓞𝓯 𝓬𝓸𝓾𝓻𝓼𝓮, 𝔀𝓱𝓪𝓽 𝓶𝓪𝓭𝓮 𝔂𝓸𝓾 𝓽𝓱𝓲𝓷𝓴 𝓸𝓽𝓱𝓮𝓻𝔀𝓲𝓼𝓮?" "𝓟𝓲𝓷𝓴𝔂 𝓟𝓻𝓸𝓶𝓲𝓼𝓮!" "𝓟𝓲𝓷𝓴𝔂 𝓟𝓻𝓸𝓶𝓲𝓼𝓮." Yet as one received a powerful quirk and was praised for it, the other was shunned for being quirkless. One slowly became more and more prideful, and the other slipped further away. One forgot his promise, and the other was bullied until one final nudge was all it took. The string snapped. The perfect circle had cracked in half. The siblings went down different paths. One was determined to be a Hero, for the other, for their dream. The other pursued the path of a Demon Slayer, working to protect in the dead of night. When they finally meet again, both recognized each other. He wanted to apologize, but she was no longer the same. The siblings had became strangers. Mere acquaintances.
