Weekly Jump magazine had a little tidbit on The 3rd Birthday this past week. Their grand reveal? That Aya has a maid costume in The 3rd Birthday.
Judging by the screenshot, it appears to take damage just like all her other costumes, too. You’ll just be losing your stockings instead of your jeans in this case.
Wondering what that heart-shaped bubble on the top-left says? It’s "Irashiamase, Goshujin-sama…" which roughly translates to "Welcome, master…" (Although, "goshujin" by itself is also the Japanese word for "husband" in case you’re curious)
It’s interesting that Square felt the need to include this sort of fan-service in The 3rd Birthday. Poor Aya. It’s a wonder she has any of her pride left…
