If you get the evo version for Zero and Ao then maybe you'll have an easier time understanding the story if you're better at listening than reading. Most of the main events in those games actually have a good amount of VA.
I thought about it, but I think that I'm doing myself a bit of a disservice by playing very long games with limited understanding, so I'm unlikely to do what I did with Sen 2 again (Though I do credit it with teaching me a lot of new kanji. Haha)
I'll just keep working on my Japanese, bit by bit, and hope that in 3 years or so I won't have to worry about such problems anymore, either from myself learning or from XSEED being superheroes again.
(The Zero battle theme is SO DOPE, it will be hard to resist though)
