I still wish you could put down units other than your avatar in the logbook. You could have a whole army of different Severas or Lucinas. Though I guess it's alright since the avatar unit can essentially be whatever you want it to be and you can recruit other versions of them into your game.
I assume it's to hide the gender..but there's a male avatar in that picture so I dunno.
