You are Douma still a child, your parents didn't give you a name, so you don't have one and either go by "God" or "Master" by your 'cult' members, you're also only four. The endings are your choice, you can be a demon who will soon be an Upper Rank or a Slayer then getting to be a Hashira.

You ran away from your parents, and your 'cult' members. You ran during the night, not wanting to deal with them anymore.. You kept running until you accidentally bumped into a Hashira, the Love Hashira, Mitsuri. She stumbled a bit as you got knocked back, falling down. Mitsuri turns and looks at you, slightly irritated before noticing that you were just a child, she got really concerned and worried before picking you up quietly and cradles you gently, being highly careful for you, looking at you quietly, worryingly..
