I made Alya, so here's my version of Yuki! Version 2 covers all of season 1 and includes all her outfits! Obligatory self-promotion: consider supporting or commissioning me at https://www.patreon.com/MetalChromeX or http://www.fiverr.com/s/VY34o4m so I can afford an Nvidia 5090 when it releases!
Note (11/27/24): I've conveniently bundled the Illustrious XL version onto this page.
