She is a master pharmacist that prepares medicine at the Eientei, and sells it (*1) to both human and youkai.

She has only recently started this business.

Her medicines are divided into consigned and direct sale varieties. Consignment operates by distributing medicine boxes to each household, and at the turn of the season the usage is checked. Only the price of the consumed medicine is then charged.

Those are medicines to heal light injuries, colds, etc.

Direct sale medicines are purchased in-person at Eientei. There are ones such as short-lasting medicines, medicines for serious illnesses and medicines for special cases.

Her medicines have a reputation of working efficiently and without side-effects.

However, there is but a single warning. Medicines for youkai and for humans are very different.

Medicine for youkai are too strong for humans and they will suffer from side-effects.

On the other hand, medicines for humans are poisonous to youkai.

Also, if you go to Eientei, she can examine you just as a doctor would.

It's said that she can provide medicine even for unidentifiable diseases (*2).

1: For a fee. She doesn't make the deliveries herself, the youkai rabbits do.

2: But then again, even if you go into the Bamboo Forest of the Lost, there is no guarantee that you'll reach Eientei.

She is not overly concerned with payment her services.

Her medicines are not only very effective, but carry a fair price. And even if you can't pay immediately, she will wait however long it takes for the payment.

Even if if you suddenly fall ill while poor, she will kindly examine you.

And this is for both human and youkai.

The fact that she has appeared all of a sudden and started treating people's illnesses, and yet doesn't seem to be motivated by money, gives an impression that there's something else to her behavior.

She seems like a kind human at first impression, but since the reasons for her kindness are unknown, she sometimes makes people uneasy.

She is a model person.

But nothing is for free.

There are a lot of mysteries about Eientei, but she is the most mysterious part of it.

Where did she gain her knowledge about medicine? Why can she make medicine for youkai as well? What was she doing before opening her pharmacy business? And many more yet unanswered questions.

Her age is also unknown. Although she looks young at a first glance, her manner of speaking and behavior are characteristic of someone who has lived a long time, which only makes the question harder to ask.

And especially strange is that, even though she possesses extensive knowledge, she is lacking of more general common sense.

If you ask her about this, she'll answer with an incoherent response like that her skin looks so smooth because she made a rejuvenating medicine (*3), and won't talk any more about it.

Rumor has it that she is a human with a deep connection to the Lunar Capital.

The fact that there are a lot of events and people associated with the moon at Eientei, and that rabbits are the ones that distribute the medicine seem to give support to this rumor.

It wouldn't be strange if her advanced medicinal practice was the moon's medicinal science itself.

There's a possibility that, through some way, she has obtained the technology from the Lunar Capital.
