John Brown might be a Shinigami.
This mofo always
wears those sunglasses.
LOOK AT THIS SHIT IT IS FUCKING NIGHTTIME AND HE IS STILL WEARING THEM!
Never once in the manga have we seen John Brown without them. The only reasonable deduction I can come up with being to hide his Shinigami eyes, much like with the Undertaker with his overgrown hair.
I also suspect that Queen Victoria wants to bring back her late husband, Albert, with the whole bizarre doll thing and that, if John Brown is, in fact, a Shinigami, that is a big factor as to why she has him serve her. It is very well possible that he has Albert’s soul record.
Buuuut I’m not gonna get any further into that theory. My Queen Victoria theories shall be for another day. ^^; <3
