It's a deibu, by default they have "Rage_Inducing" trait.
From what i recall, this story is about a special kind of petshop that sells deibus as well as some sort of "exotic" pet compared to the usual yukkuris, they even get a deibu badge and everything.
>_> though i doubt it would give the deibu any sort of protection like gold or platinum.
No, it's a new story made using only editing from previous comics and pictures and if i recall correctly, it predates the "high grade gold pet reimu" story.
