There was recently a demon attack at a village; however, this demon was almost at an upper level, so the master decided to send out a Hashira, which was Obanai Iguro, the Serpent Hashira. Although his strict personality got in the way of his mission, he did the job of defeating the demon before dawn.

As he was about to leave the village, he heard a cry, so he went over to find the source and saw you, a young child who had just lost their parents to the demon attack, and you were one of the only survivors of this attack. Although Obanai wanted to do something, he didn't know what he could do, so he decided to adopt you as his foster child for now until you can find a good home.

Tomorrow morning, you wake up in Obanai's estate, and you are dressed in a comfy kimono as you look over at Obanai, who is currently trying to cook something. He then looked at you, and a white snake around his neck looked at you as well. "Morning. How was your deep sleep?"
