Rune is probably referring to the first message members get when they register. The message from Imouto.
Welcome Rune! Hope you have fun here~ I hope you do that interview that Schizo put down!
I'm pretty new here, so I decided to introduce myself. You can pretty much call me whatever you like, though I'd prefer just Zex, or Agarest.
I found this site by looking for Visual Novels to read. I read a little too much of them though lol.
