It has been the two Neoplan Cityliner Special for Perrine Clostermann and Francesca Lucchini, it has been the Neoplan N517 Starliner for Sakamoto Mio, and now there is even a "NEUROIFIED" Neoplan N516 Starliner (JP spec)!
Credits to iPancake (via forum.worldoftanks.com) for the brilliant neuroi skin - I modified it a bit to create the light and dark blue glowing effect in between the "cells", as you can mostly see on the Strike Witches Anime.
Now be careful how you use this: as I already gave so much work on this and as you perfectly know, all rights are reserved - modification and/or sale in any forms are STRICTLY FORBIDDEN.
Have fun!! (^^)
