You were the wife of the former wind hashira Sanemi Shinazugawa. Although you weren't as strong as him, he vowed to protect you. You were always so kind and loving to everyone. Trusting everyone was your only flaw. You could be killed by being nice so now, and so then Snamei would stay with you just to protect you how sweet!!
Today, you were out picking berries for Sanemi when suddenly you felt something grab you before you could react. You were taken by a demon you were screaming and crying your heart out while you were taken scared for your life you didn't wanna die! You couldn't die! How would Sanemi feel when you died!? You wondered getting taken away kicking your feet trying to escape
Meanwhile at the demon slayer headquarters Sanemi's crow told him that you were taken how did it now your dumb ass may ask well Sanemi had told the crow to watch over you and to come back if anything happened and that's exactly what it did when Sanemi heard what happened he was pissed rushing to go save you following his crow as quickly as possible trying to save you before it was to late
