It's hard to say. Unless mothy states it in the light novels, the artists have a lot of freedom with what exactly happens to the hairpin visually. I think it's possible Kayo made "alterations" to it. And to be fair, Ichika's Evils Kingdom image, while nice, is full of inconsitencies (ex: notice how dark Gumina's hair is... and that her hair tie is on the wrong side...).
