If you want to take the north path too (you should) then go to Windy Peak.
Windy Peak
Windy is here to intercept you. She has some powerful and stun-able attacks. This is a good battle to get the twins in.
Beginning the battle, use a Were on the rock by the six special spots. This will reveal a Magic Potion. There is another treasure at the other end by the two rocks that are by eachother – destroy them and get the Charm of Magic.
For the first few turns you may wish to position a few characters on the spot that makes walls come up. This way the bandits can come to you and once they are scattered, you can continue on. Otherwise you’ll be getting StunWind attacks while fighting bandits.
Unleash everything once you get to Windy and again, don’t forget the Charm of Magic in the pit with two rocks.
Old Man Nyoi confronts the group and you’ll learn about So Gojo’s past.
Inns Town
Head to Inns Town now. At the Inn, Kikka will pass out.

Have you ever wondered about Sanzo?
Great guide
