The Something in the Water Walkthrough

They all went to get water from the Otowa Waterfall, but something in the water has caused the man to fall sick. Lady Murasaki says the water there is famous for bringing fortune to people so it's curious that it would bring disease instead.

[2] Investigate the waterfall.

Go to Otowa Waterfall as seen below in Kiyomizu-dera Temple. You can talk to people on the way and they will be commenting on the waterfall.

Talk to the woman there. She offers to pour Musashi a drink from the waterfall and is then offended when he rude rejects her. Lady Murasaki says the waterfall is maintained by Yasahajin so maybe there is something going on them with them.

[3] Investigate Yashajin Hall.

Yashajin Hall is further into the temple grounds. Visit it and Musashi will find it entangled in the Genma threads.

Use Oni Vision to find where the threads lead and destroy the spiders making them. Use the Oni Bow for both of them.

Examine the water. It is no longer contaminated.
