doubt it, maybe another time... nuatku own the rights to koihime and koihime has an english version, whereas nutaku don't have walkure romanze on their site and i don't think the game is in english? something like that..
There doesn't seem to be an official English version of the VN anywhere, so it's probably a rights issue.
Glad we're getting another Crucible though. I really could use those mats and I love my dark team.
