Kusa Susano Skip
In Kusa Village, Susano can be found sleeping next to the small bamboo grove near the entrance from Taka. Because the cutscene trigger completely covers the path from Mr. Bamboo's house to the village square, this cutscene is intended to not be optional.
You can skip this cutscene trigger by performing a somewhat precise Vine from behind the trigger to the flower that Ammy takes on the way to feed Ko in the cave. During this segment in NG runs, you are normally locked into the day-night cycle between Blooming Taka and fighting the Cutters. Because cutscenes and dialogue pause the day-night cycle, skipping Susano here saves approximately 2-3 seconds in NG.
This can be done after feeding Chi next to Mr. Bamboo's house by jumping up to the ledge on the right, performing an Air Ground Tackle off the ledge toward Susano, then doing a delayed jump followed by an air tackle bounce off the right cliff-face for maximum height. At the peak of Ammy's arc, brush and Vine. Ammy should be pulled over the upper path and to the flower.
