I tried scouring the net for it (for MMD purposes), downloaded the game in the hopes that I could rip it from the files (but sadly, it's all prerecorded footage), and now I'm here.
The Liru models that do exist out in the wild are... not up to standard, at least when compared to Seismic's rendition. There were some talks about someone making their own version of his model, but the trail ran cold.
I'm pretty close to giving up myself, but I'm curious if anyone has one that's actually good.
