that's because you're waifu [spoiler]a shit[/spoiler]

On a serious note, making models from scratch is a decent amount of work and side characters from seasonal anime often don't have ones already made. A cursory search on 3d.nicovideo.jp doesn't turn up much for TPN. You might be able to find something deeper in the Japanese internet but I'm afraid that's beyond my ability to help you with.
