Ever wonder where Susano and Kushi got to during the festival? Well if you find them, Susano will praise you and call you his buddy or brother. Heres how you find the couple:

1) It has to be during the festival, after you defeat Orochi.

2) Go to the sacred tree in Kamiki Village. Go inside there and find where you got your cut technique. The cave where a giant statue of Susano's ancestor is. Where you had to in the sword.

3) The couple will be standing in front of the statue. There may be hearts coming from their head. If you talk to them they will begin to mummble in embarrasment.
