Yako's most striking feature is her long beige hair, tied back with a red and white ribbon adorned with small bells that give off distinctly fox-like vibes. In her true form, though, she's just a small white fox—nothing fancy. She used to be an inari statue standing guard at a temple gate, likely somewhere near Misaki's school, before things got weird and she ended up as. well, whatever she is now.
She's got complete control over the Misaki Stairs, which is basically her territory. The boundary kicks in at the 4th step—that's the entry point if you're trying to get in.
