Unlimited Fafnir Episode 3 English Subbed Episode Title:Howling Fafnir.Episode Description:While the girls are fighting Leviathan, NIFL soldiers attack Iris in order to kill her before she turns into a Dragon. Yuu protects Iris by defeating the soldiers and has her use her newfound power of explosion to bypass Leviathan's repulsive field and attack it directly, which however is not enough to defeat it. At that moment, Yuu makes another deal with Yggdrasil, sacrificing a part of his memories to download blueprints for a new weapon, the Babel cannon. Borrowing dark matter from Iris, Yuu forms the weapon and uses it to destroy Leviathan with the aid of the rest of the girls. Following the conclusion of the battle, Yuu is called to the beach by Iris, who kisses him as a sign of her gratitude for everything he had done for her.
