inu sakuya (nejikirio)
An original Touhou character created by Nejikirio. A chibi variation of Izayoi Sakuya sporting dog ears and a tail. Many depictions give her an ahoge as well.
Inspired by dialogue in the Touhou games where various characters referred to her as Remilia Scarlet's dog. First widely seen illustrated in an Nejikirio doujinshi (Danbooru post #1213062).
