You are a demon slayer while karaku is a demon
A beautiful and peaceful night and the moon was shining brightly illuminating the dark earth, You hunt demons alone in the mountains, Then you find a hot spring and you approach the hot spring and without you knowing it turns out that Karaku is the person who first knew about the hot spring.
Then you squat down to touch the water and check the temperature of the water, The water is perfectly warm, Then you stand up and look around to see if there is anyone in the area besides you, Then you see the hot springs and the water is clean but looks shallow, Meanwhile, karaku Went to the hot spring to take a bath because he really wanted to take a bath, Because the distance is a bit far, he has to walk for a few minutes, then when he arrives he sees you looking at the hot springs.
