#Sannyo actually is in a Zounose doujin. But all she does is play a round of Chō-Han with Reimu at a market.

The popular Yokai question

Does Sannyo eat humans?

No. Almost definitely not.

Despite being a huge fan of absolutely all their doujins, I'll take this a step further and say not even the legendary Zounose could make it convincingly happen.

There is simple reason for this. Sannyo is a Yamajorou. This means if she were to do it, she'd need to do it in her den, much like how Nemuno would invite someone to her home, or at least be territorial. To do it aside from her nature as a Yamajorou/ Yamanba wouldn't make any sense.

Doing it inside her den would be a pretty cool mental picture, except we know she doesn't. (Or at least if she does, then not in the literal sense)

Not only that, we can get evidence even beyond that.

In her Unconnected Marketeers dialog, unlike many Yokai in the series, she actually doesn't threaten to eat anybody in game; in fact she does the opposite. She basically just says: "you're a human? Get out. I'm not going to sell cards to you, rainbow dragon cave is like totally hella dangerous yo. Run back to the foot of the mountain or I'll kill you myself."

In contrast, Nemuno invites people over to her home even after losing, as expected of a Yamanba; which Reimu hilariously responds to with: "No, I plan on living a long life".

The only way Sannyo can be a Yamajorou properly is if simply welcoming people into her den and having them indulge is what feeds her, whether they be human or Yokai, or just using her power, the point is it needs to happen in or near her den/dens because she's a Yamajorou, at least to some extent.
