After Kana petted Espi to the content of her heart, Aster unfolded the sleeve of his coat, covering the cute little thing, to let it rest.
Aster didn't expect to find Espi coiling around his arm uncomfortable, he had petted the little wyrm previous to its evolution, and its scales were surprisingly smooth, without having the moist sensation that reptiles back at earth had.
Though Espi looked like a snake, ultimately it was a dragon, the scales on Lilia's wings and Alice's tail, were also way different than whatever reptile Aster had read or heard off back at earth.
Anyway, though he didn't expect to be uncomfortable, he was surprised at the fact that if he didn't pay attention to it, he wouldn't notice that the little thing was coiled around his arm.
Could be because of Espi's adaptation and hiding capacity, which is what allowed it to escape the scope of those who hunted the other wyrms back at Esmeralda's secret realm, or it could be due to the contract between them.
