We never see much of SailorPluto. Being the Guardian of Time is a very time consuming job. (No pun intended.) And even though she appears a season ahead of the other Outer Senshi (In the R season instead of the S season) we see the least of her.
One of Pluto's main concerns is protecting SmallLady.
