Stir the Storm of Flames! Yuna and Souma's Friendship!.To increase his power for his rematch against Yuna and Söma, Methone uses a dreadful item given to him by Europa to kill his sister Ymir and drain her Cosmo, and the two Bronze Saints must combine their strengths against the empowered Pallasite, as they reminisce upon the day they first met. Realizing the true power of friendship, Söma and Yuna eventually overpower Methone and defeat him, him being killed by Ymir's spirit moments later.
