Not Exactly A Guardian Angel

Read this like ten times over and I think this one might be cash money enough to be on here. First time legitly posting a story here, and I think that these three particular characters don't get too much recognition, so hopefully you pick up what I'm putting down. Oh, and you'd probably need to know this; I've included Sword and Blade Knight as part of the Meta-Knights just because I think it's weird that they're canonically not.
