[Ghost Slayer] Looking for a Destined Person to Send Me on My Way

My name is Steel Pill, and I have lost my memory. The beautiful sister who picked me up said that I was a decent person when I was alive, but for one reason or another, I became what I am now. My beautiful sister has a companion who is very annoying. We often fight secretly behind my beautiful sister's back. I think he is not only a stubborn dog, but he also covets the body of his beautiful sister. He is so evil! I was excited at first to find out I didn't have to eat or sleep, but then I found out. I can't taste my food, and it turns to ashes when exposed to the sun. While walking on the street, I looked at everyone who was greedy. They all smelled like big roast chicken with long legs, but I couldn't eat them. I really can't bear this grievance. I want to die but am afraid of the pain. I heard that there is a person in the Demon Slayer Squad who is good at transcendence... Tanjiro:? Motto: As long as you live, good things will happen
