This is turning into something weird, but is very funny
But I would like to know if there are people here able to talk like this about other characters.
As far as I can tell, V-Akiha isn't really more popular than many other characters. This discussion really just happened because Master_Rahl brought up the infinites and I was shocked in my naivety.
If you want to look into other characters, the wiki that Sacchin 22A posted is where I get a large chunk of my information, and then you can go the specific sub-boards for your character of interest and browse through the threads or ask questions. To this day I'm still surprised at how quickly and actively people reply.
EDIT: I'd suggest C-VAkiha over C-Aoko, if only because I think C-Aoko is a really high skill cap character that takes a lot more practice than you'd see with other characters. I used to play C-VAkiha for a while before I switched to F-VAkiha because I wasn't really satisfied with the results I was getting, but you could be different.
Funky-Kun has a lot of great information on her
here, and you may also find some good info on the wiki
here, although keep in mind that the information from this wiki will give you V-Akiha info from the previous version of the game, Actress Again. Most of it should still be relevant, though.
