"Front Oni" and "Back Oni"? What's referenced here?

I don't see Ran or Chen...

The spell circles have "yakumo ran" and "chen" inscribed in them.

But Danbooru doesn't work that way. Tag what you see it's how it works and neither Ran or Chen are physically there.

"This ain't even my final form!"

First spell card here . Also, more details available here and here .

This is quite a break from zounose's usual style. Love it just the same though. Great artist IMHO and his/her coloring is something truly unique.

On a side note, the monster mug under Yukari's skirt reminds of Odin Sphere's Odette.

Zenki and Gouki (前鬼 and 後鬼, in the lower left circles as you saw) are a famous pair of oni, husband and wife, that served En no Ozunu, the historical founder of Shugendou, as shikigami. A pair of bird shikigami with the same names (whether they were intended to be the historical figures is unclear; the ability to change forms is common for shikigami) also appeared in Silent Sinner in Blue serving Yukari.

Edit: Or I guess Moonspeaker already linked most of that. Oh, well.

Hey, I didn't know about the SSiB angle, so it wasn't in my links, plus some readers don't like linking out to get info, so I don't think you wasted your time.

So, Yukari has an Octopussoir? =D

But they are, just as spell circles.
Magic bruh.
