I'm actually pretty disappointed in this mod. I kinda thought she would make... I don't know, Miku sounds? Maybe she would sing while she chased you? But no, the guy just took a Miku model and stretched it over the Leyak skeleton and didn't change anything else.
On the plus side, since the Miku model absolutely does not fit on the Leyak skeleton at all, when she attacks the model stretches and deforms in horrifying ways and her arms turn into spastic noodles that flap around wildly. It's way, way more terrifying than the regular Leyak.
