if Silver is Gray's father, I have a feeling there'll be a shit load of memes and comics doing that whole Vader line getting done way to death

I hope Mira doesn't run into that guy, what with Satan Soul and the fact that he froze and entire village just to try to kill a single "demon"

(Silver and Gray are shades of the same color, which may be a further hint of the relationship)
