Dextrins are white, yellow, or brown powders that are partially or fully water-soluble, yielding optically active solutions of low viscosity. Most of them can be detected with iodine solution, giving a red coloration; one distinguishes erythrodextrin (dextrin that colours red) and achrodextrin (giving no colour).
Yukine (éªé³, lit. sound of snow) is one of the three main characters and Yato's only Shinki. When the name Sekki is called, he transforms into a silver katana, the handle of which is loosely wrapped in bandages.
In his human form Yukine appears as a youthful teenager with short, messy hair. His hair is colored gold both in the anime and manga colorations. However, his eyes are colored a reddish-orange in the anime and a yellow-amber in the manga. He is shorter than both Yato and Hiyori at only 155 cm (5'1).
