Catering to Renaissance Fair attendees (perhaps?), Square Enix decided to give Aya Brea a Knight costume for The 3rd Birthday. You can’t see it from this angle, but the costume exposes Aya’s back to the Twisted and a player’s gawking eyes. Even though it really is greaves and a leotard, this outfit, compared to the Maid uniform, seems a tad more reasonable.
The scan from this week’s issue of Famitsu also shows a new weapon. The gun-like weapon Aya is holding is called a Pile Bunker. It acts like a blunt weapon in the game. So, you can essentially play "knight" while whacking Twisted with a two-handed gun.
