We admit, this isn’t any specific dragon from any anime we could place. It doesn’t look like anything from Miss Kobayashi’s Dragon Maid, Magical Girl Lyrical Nanoha Strikers, Digimon, Shingeki no Bahamut: Genesis, or anything. The best we can guess is that this looks like it could be from a brood sired by Haku from Spirited Away, but even that’s a stretch.
However, it is a clearly anime-style dragon that makes a cute, cuddly companion and a handy neck pillow for traveling to and from the anime convention on the hotel shuttle. Just consider it a stand-in for the various dragons in anime, and go on about your geeky business.
