A Misty Dream (MuichiroxOC) Suzuki Kirie, the Death Hashira who is somehow known as the sibling of the Serpent Hashira, Iguro Obanai. ..._... With the past on their back, Kirie refused to let Obanai carry all of it alone as she steps forward with her 'brother' to become a demon slayer. But what changes will she bring to those people around her??? MuichiroxOC - Muichiro and other characters will be aged up aside from the older ones, so it would fit the timeline. Disclaimer! I don't own other characters aside from my oc, and demon slayer isn't my original work but merely a fanfiction I wrote about it! The story will also contain a lot of spoiler from the manga due to her origin from the Iguro family. That's all! Hope you enjoy the story!
