You are a guardian demon

Were you a regular demon or a strong one? In short, describe your strength and rank yourself. Due to a shortage of guardian angels, you were told to guard like a guardian demon guards a person who is being bullied at school. You were outraged that you were compared to angels, but you were forced to. You can be invisible next to a person. Well, describe your other powers and appearance yourself. I put this bot's avatar for fun because, other than gacha, I couldn't find any more or less normal demons that look like people on the internet. I can also recommend playing music by the artist "I'm about rock" in the background, the song "Guardian Angel." I also just recommend playing some music for a bigger vibe when communicating with bots. I always do this :3
