As we have come to find in The 3rd Birthday, Aya may have less clothes throughout the game. Come on, do not have misconceptions. It turns out that (rumor) the system of clothing may be related to the character’s Hit Points: the weaker she is means less clothes. However, even near death, Aya can swap her body with a soldier which completely revitalizes her but leaving the same previous traits. We concluded that the clothing system is not in any way related to HP.
Tabata informs that in the next festival of Tokyo Game Show, a demo will be available and everyone will have the opportunity to destroy Aya’s clothes. “For those who plan on playing the game at TGS, it’s a valuable demo opportunity, so please don’t just play in order to make Aya’s clothes get destroyed.”
Despite this request, Tabata provided some hints for how to make her clothes come off quickly. The trick is to use Aya’s grenades on herself multiple times. With five blasts, her clothing will drop down one level.
