So.
This is a Sailor Moon, Ranma 1/2 crossover.
Why?
To be specific, what are the senshi there for?
So far, apparently, their role is to go, "Ooh! Aah! We are
insignificant before your godlike magnificence and we grovel before
you, insect-like superheroines with the power to erase all life from
the planet that we are."
Exactly why do the Saotomes need these second-raters? Clearly the
sensible thing to do would be when they see a demon to call up the guys
with the power to handle the situation and then go home. Or maybe do
crowd control.
Now, to be sure I have serious doubts about Akane or even Ranma being
that powerful. Cologne isn't that powerful. Happosai isn't that
powerful. And while it's not unreasonable that Ranma at his height may
be somewhat better than those two masters, it seems to me unlikely that
Akane would ever be so great as to overshadow them into insignificance.
I particularly balk at the idea that Ranma and Akane could stay that
good without doing any practising. Martial Arts is not like riding a
bicycle. If you don't use it, you lose it.
Given that you have revealed that Ranma and Akane were rocketed to Earth
from a far off planet as children, the question remains: the role of the
Senshi in this partnership is what exactly? Well...I suppose they do
dress like cheerleaders.
A word of advice, though. Batman-Superman team-ups do not rely
primarily on repeated demonstrations of how outmatched and insignificant
the man in the cowl is.
