Re:Zero kara Hajimeru Isekai Seikatsu Episode 19 English Subbed Episode Title:Battle Against the White Whale.Episode Description:In the new timeline, Subaru changes his approach, deciding to defeat the White Whale before going after the Witch's Cult. Knowing when the White Whale will strike from the previous timeline, Subaru offers Crusch's camp an alliance to battle the White Whale in exchange for shared mining rights of magic stones in Roswaal's domain. She agrees when Subaru uses his cell phone to show the time and location of the attack and offers to draw the whale towards himself. Anastasia's camp also agrees to join the campaign, viewing the whale's presence as detrimental to her interests as well. Crusch is impressed by his skill in gathering support, and Wilhelm lets Subaru know that his wife Theresia, the Sword Saint, was killed by the White Whale created by the Jealous Witch and has devoted his life to defeating it. The next day, Subaru and Rem, riding a ground dragon called Patrasche, with the armies of the Crusch and Anastasia camps, head out to the Flugel tree to wait for the whale to appear. That night, the whale appears at the moment Subaru said it would and the battle begins.
