The roster hasn't been touched since 2016. Add whatever you want. Requesting systemd be renamed to systemd/GNU/Linux
PES doesn't use skeletal rigging, so with a humanoid model like animu we can just change the pose, transfer vertex weights (for rigging animation) and convert the textures. That means any 3D model of Lain should be fine. I would assume someone's made a MikuMikuDance (MMD) model, I can port that to PES easily.
