It was limited in 1992, but we did have internet when Sailor Moon was released. In classic, instances of the internet were used. And, Japan has always been a bit more progressive technologly so you're not saying anything that wouldn't have been true back then. Missing sailor soldiers would've been a local news story easily found online even as limited as it was then.

That does answer a lot of questions.

What happened to all the other chapters?

Awesome of course.

Oh, my. I wonder who this person is.

Mercury has Moon Healing powers!

Sailor Guardians are overrated, it’s all about ninjas and superheroes now.

People love burgers.

Sailors forever!

And he at least knows what one of them looks like as a civilian...

Chibi-Usa is getting a trip to the Multiverse

And here we are with a reminder that there are other people having adventures that the main character will never know about .

A new Empress will rise.

Be cool.

It's not as if all of the people working for the Dark Agency were stupid enough to make targets of themselves. Jadeite might end up meeting an old subordinate.

Also, the regular person would have zero clue as to what's going on with the Sailor People.

Magic is always with us.

Will Sailors Chi,Phi,Lethe,and Mynmosyne be in this story?

Oh, goof grief. Again with that idiot. The Animamates are as good as dead with that imbecile working for them.
