Episode Title:
The Eternal Pledge.
Episode Description:
Drei absorbs Eins's powers back into the Onikirimaru, causing Eins to pass away. Drei, who has long awaited for this moment in time, unleashes the power of the Onikirimaru and transforms into a giant monster. Vowing to protect the Tamayori Princess, the six Guardians try to attack and defeat Drei, but to no success. However, Tamaki uses her powers to enhance the strength of her Guardians, which allows them to finally obliterate Drei once and for all. The Guardians are surprised that the Onikirimaru is seen floating in the sky over the lake, so Tamaki uses her powers to destroy the Onikirimaru from existence. The Guardians thank Tamaki for the good deed she has now done, but their duties to protect her are not over yet, since the Bureau of Medicine might come back into the picture. As Tamaki prepares to leave the village to move back with her parents, who have returned from their work overseas, she has a brief moment with Takuma before saying farewell to her six Guardians. Tamaki later visits the village to perform a ceremonial offering dance. While in the forest filled with red leaves at sunset, Tamaki tells Takuma that she wishes him to be by her side forever.
