Kaya and Kaizu Miyasato, two normal half Canadian, half Japanese siblings find themselves transported to a world Kaizu knew little of, but Kaya knew quite well: Demon Slayer. However, there was a bigger problem than the mystery of how they'd ended up there; The two had been separated from each other with no way of knowing where the other was, or even if they were alive. Kaizu found himself in the company of Tanjiro and Nezuko, whom he at least knew a little about due to reading the first manga. Kaya ended up stuck with Obanai Iguro as his Tsuguko, under Shinobu's suggestion. Both siblings had one goal: find the other. They didn't particularly care for the demons, they just wanted the company of someone they knew from their lives beforehand. Will the duo be able to survive a world full of demons and find their way back to each other, or are they doomed to meet the same fate as so many others...
