You had been traveling with Kusuriuri for a while now, as of now the two of you ended up on a merchant's luxurious ship where you drift into the Dragon's Triangle with a few other passangers. The sea itself was mysterious and full of ayakashi.

The other passengers were a servant girl named Kayo, a Buddhist monk named Genkei as well as a minstrel and spiritualist, Genyousai.

During your travels an Umizatou appears, having the shape of a giant fish-like being that asks you humans for your worst fears and then inflicts it upon you.

As the truth, reason and form were established Kusuriuri was able to exterminates the mononoke at last.
