The defenders of the galaxies, the sailor scouts know to reside in Japan but are the scouts, the protectors of Earth only in Japan?

I know for a fact they aren't because I'm a sailor scout…. one of the only two groups that have anything to do with space to be honest. Japan's Scouts are based off planets and then us… the Canadian branch…. I can't say exactly what we're are, it seems barely connected.

Asteroid, brilliant streaks of light we see across our sky that could actually be destructive to us

Atmosphere, the barrier that keeps life protected and is forever appreciated yet barely thought of

Black Hole, a vacuum meant to clean the debris of the galaxy and feared due to it's destruction

Gravity, the force that stops people and planets from floating off much like Atmosphere

And then there's me, Void. The horrible dark abyss that few enjoy thinking about and those who do spiral downwards, forever unloved, forever alone, forever darkness.

Yet for some reason:

I, Sailor Void, the pretty guardian in a sailor suit and the Champion of Balance and Justice am the leader of the Sailor Guards.

As for who we fight it's about the same as the sailor scouts, what villain would attack only one place that has defenders in it?

Either one with a the goal to only take over that place or a stupid one.

The Negaverse, Black Moon Circus and Sailor Galactica all attacked elsewhere on the planet, including Canada only the attacks on us were weaker.

But now, we have our own threat. One that's main focus is here, and me and my friends must defender the Earth as best as we can.

By my Galaxy Keys I swear, I will do my best to protect my planet and the only friends I have!

I'm just scared that I'll fail or someone or thing else will separate me from them...
