In the forest, Takatora is saved by the Over Lords and introduced to their leader Rosyuo who tells him of their past as the Femshinmu people and the secrets of Helheim. Later, Kouta, Kaito, and Mitsuzane all search the forest for Sid, but Sid has set a trap for Kouta. Then Kouta fights with Zangetsu Shin in Helheim Forest, unaware that it is actually Mitsuzane attacking him using his brother's weapons.
