CascaxJudeau

CascaxJudeau is the het ship between Casca and Judeau from the Berserk fandom.

Canon
Throughout the Golden Age arc, Judeau is shown to care consistently care for Casca. Shortly before charging toward a battle, Judeau notices that something is wrong with her, but he doesn't know exactly what. What he does know is the bond slowly forming between her and Guts. While the latter is away and the Hawks are being hunted down, Judeau is the one who makes sure Casca gets a good night's sleep and proper nutrition. When they reunite, Judeau encourages Guts to take Casca with him.

During the Eclipse, Judeau swoops in on a horse to save Casca from a monster despite her wanting to stay and fight. She later saves him by stabbing a monster that bit down on his arm. When their horse is tripped up, they fall over and see another monster with whip-like tentacles. Judeau shields Casca, who cries out to him, as he is repeatedly lashed and impaled by the monster. He looks to her and throws his last throwing knife into the creature's eye. Casca then comes in and slices it in two. The mortally wounded Judeau tells Casca to go on without him, but she vows to make him carry his word to make it to the end even if she has to drag him. In his final moments, Judeau contemplates that there were so many things he wanted to tell her, but he missed his chance. He tells her that he thinks she cries a lot when she's alone. In his thoughts, he regrets that he messed up his last words before dying and falling from her grasp. Casca is barely given time to mourn his loss as more monsters set upon her.

Years later, when Casca overcomes her trauma from the horrific events of the Eclipse, one of the first things she notices about Guts is that he now carries a set of throwing knives as a tribute to Judeau, then she suffers a panic attack while remembering his sacrifice.
