I know it's a bit different from other novels, but this is how I'll write:

,, ... " = Someone says something 

" ... " = Someone thinks something

... = Narrator (No symbols)

*...* = Location or sounds

If it's a group or it's unclear who speaks or thinks something, it will be shown as this: 

/Aera/

,, ... "

/Hunter 3/

" ... "

Don't ask me why... I always wrote like this as a hobby and it stuck with me... I may not be able to change it unless it's absolutely unbearable for you guys. I hope you can understand...
