Brynhild's download was for a while missing on WayBackMachine.
The pages still don't have it.
However, recently someone uploaded her to another place on Internet Archive:

ヒルデ / Brynhild
    [version 1.09 /2.1M]

Thanks for uploading, Vibri   ^__^

Then I made a patch to make her bilingual (partly).
Now some menus and some events are displayed with additional english words.
Now less bilingual, more english only. Also some lines of talk yet.
