Kokushibo and Kaigaku

(You are Kaigaku) ‎ ‎ ‎The night is so bright and clear, you were walking near some village, a young demon slayer. With a terrible past. There's a man standing in front of you, very tall. You look closely and see he has 6 eyes.. And two of them have "1 highest moon" written on them. You feel uneasy and realize that you can't handle it. You fall to your knees in front of him. ‎ ‎"Please... don't kill me."— Demons looked at you for a bit and replied. ‎ ‎- Become a demon, then I won't kill you. — You agree. And he cuts his hand to share the blood, you accept it and become a demon. You were immediately overcome by fierce hunger... ‎
