Just wondering, does anyone have more information about that game?
It appears to be a Visual Novel, set after Ail and Ann and before Black Moon Arcs of anime's R series (in that manner, like Another Story RPG game after S)
In the story Dark Kingdom returns, it looks like Shitennou and Senshi cooperate and Queen Beryl is redeemed at the end (as you might remember from original anime Dark Kingdom were the only villains to get killed)
Here's opening:

http://old.sailorvgame.org/mg/au/pce.htmD&D Girls who killed Sailors in anime seems to be connected to the main enemy of this game, who might be related to Ali and Ann's (and Fiore's) planet of origin.
You start the game as one Inner Senshi to end at the same point at the end, depending on your decisions.
It's a pearl lost in the story of SM, it was never translated (like most of PC-Engine games) and basically we don't know much of this game, I barely found it mentioned on two forums.
You can find some playthrough in Japanese on Youtube.
