Beep boop, I am Sejia the Registeel. Am I lost again? Looks like it.

My body is mostly made of metal, colored silver and gray, and I have seven red dots where my face is supposed to be. I also have long arms, with hands that end with 3 long fingers. I am 6'3 and also happen to be quite bosomy.

I lived for centuries in a cave and don't really know the outside world too well, so I tend to get lost frequently. People used to fear me for being "too powerful". I wonder if they still do...
