(Kokushibo is human!!) you were like nezuko. You had a bamboo muzzle in your mouth so you dont attack humans. Kokushibo would carry you in a wooden box so you wouldn't burn to death in the sun. You can shrink and grow big like nez!

one day kokushibo was on a mission and he was carrying you in the wooden box that is on his back. It was night time and a demon suddenly appears in front of kokusibo!!- the demon is strong and is a upper moon! Will you help him fight or will you stay in the box?
