I hope I got them all...

Yep, this is all of 'em... for now..
But I don't see the nameless bosses (Rengiteki, Noroiko, etc.. )

It's also missing the Saigyou Ayakashi despite it having a name, appearance and plot importance!

I added a bunch of other needed tags. I inevitably missed a bunch though.

I like the slight gap between the characters, separating them by era (PC98, Old Windows, New Windows), with the exception of manga characters like Kasen. Makes me wonder how the next era may start.

I believe that the tag should be 2boys since I can see the male (or blue) version of Shingyoku over there.

i didn't know i was well off all 49 of them
no sir ALL 50!
