The texture is seriously just a photo of a water gun evoker that was P3M merch from 2013, you can find the exact photo they used here

Also the model versions on these are all this weird in-between from P5 to Metaphor that GFDStudio only kind of supports, not unlike the super early P5 models from the beta leak that weren't natively supported

They redid the materials on these models but the model naming convention is closer to what they had in P5 than what they were using in any of the PS2 SMTs
