After taking in the bleek state of Agata Forest, jump down the cliff. Amaterasu should land on a very slim path behind a waterfall. Behind it, there is a hidden tunnel that leads to Agata Forest's Guardian Sapling. Use Bloom to revive the Guardian Sapling, restoring life to the forest and dispelling the cursed zone. Open the chest in front of the enlivened Guardian Sapling to find the Devout Beads. As Amaterasu leaves the Guardian Sapling's cave, she will be introduced to a mysterious man called Waka, who will be faced off against in what will be the toughest battle yet.
