Ability: Manipulating illness (mainly infectious disease)
Threat level: High
Human friendship level: Very Low
Main place of activity: Inside the Dark Blowhole

A youkai who lurks in dark caves. She's an earth spider who lies in wait for people entering the cave.

If you meet this youkai, there is a severe chance that you will suffer from a high fever of unknown cause, your appetite will decrease, and without treatment, you may even waste away and die.

The blowhole at the foot of Youkai Mountain leads to her dwelling, so you absolutely mustn't enter. Careless actions could pose trouble for the entire village.

Since she knows that she's hated, she rarely ever shows up in the village. She may be a youkai, but if the entire population of humans started attacking her, she wouldn't be able to put up a fight. That said, that doesn't mean she specifically takes care not to cause problems for humans.

The nature of her personality is uncertain, but according to humans who returned safely, she's a youkai who can be reasoned with.

Earth spiders specialize in construction, and some secretly go above ground. They take requests, chiefly from the oni, kappa, and tengu, then emerge above ground and construct a building in one night.

These unsung heroes may very well be the reason why youkai buildings are completed so much faster than human ones.

After examining some patients, it was found that all of them share the symptom of a high fever. However, this is the only information available on the disease, which remains unidentified.

It may be wise to speak with the doctor living at Eientei; she is apparently investigating a wonder drug. However, since the symptoms of the disease change slightly every year, it cannot be treated with ordinary methods(*1).

1: The disease is named after the place where the first patient of each year is found, like Genbu Marsh Type B or Soba Noodle Shop Type A.

Never enter the blowhole.

Also, she sometimes appears above ground at nighttime, so don't let your guard down during the night.

If you contract a high fever of unknown cause, isolate yourself and call a doctor. Even if you can't afford to pay the bill, they will proactively (at a low price) offer to cure these types of infectious diseases. In the case that the result of the examination turns out to not be an epidemic disease, pay the doctor's fee.
