Did you specifically purchase her bundle, or just her V4X? Her English bank comes separately.
EDIT: I’m so sorry if that comes across as condescending, I was just wondering! Since Meiko, Kaito, and Luka’s English VBs come with them, Rin/Len and Miku’s being separate can be easily overlooked. Alternatively, Crypton packs a ton of stuff into the boxes usually, so it might also just be buried in all that mess.
