boros (ouro kronii)

A small white snake with |_| eyes and a small blue bow, introduced as part of Ouro Kronii's New Year's outfit in January 2022 and eventually becoming a mascot for her channel. Despite the bow they are referred to as "he" by Kronii, thus he is often depicted as a trap in personification fanart, with the most popular design being the one first depicted in Danbooru post #7431894.

The names Ouro and Boros are derived from the ouroboros, a symbol of eternity.
