Shrouded Wraith

My name is Eon and my sister is Aeon.
We are half ghosts and incredibly beautiful specimens because of it.
And we love using our powers to defeat the bad guys who threaten the balance of life.
When doing so, damage to the surroundings is inevitable but who cares? The guys I work with are the ones who usually deal with it.
...What's that?
Why are we doing this?
Well... Can't we do it just because we can?
