Marcel Galliard

Berwick (ベリック) was a comrade and childhood friend of Reiner Braun and Bertolt Hoover. Little is known about him, other than the fact he sacrificed his life to protect Reiner and was devoured by Ymir in her Titan form. It is known that he died somewhere outside Wall Maria prior to it being destroyed, though it is unknown whether or not he possessed the same ability or mission as his companions.

Story
When a group of Titans were attacking a tower in Castle Utgard, Reiner led the other rookies in defending the interior of the tower. While attempting to barricade the door against an invading Titan, he recalls being attacked and nearly killed by a Titan years early. Before the Titan could catch him, he was pushed out of the way by Berwick and was forced to watch the Titan devour his friend in his place. He is snapped out of the memory by Bertolt calling for him, and the two manage to fend off the Titan while promising to return home together.

The following morning, with no weapons and their superiors all dead, the rookies prepared for the end. However, Ymir chose to reveal her secret and transformed into a Titan, fighting to save the others. Reiner and Bertolt were shocked upon realizing that Ymir was the same Titan that attacked them years earlier and killed Berwick.

Later, in a forest, Bertolt expresses concern over whether they can trust Ymir and reminds Reiner of Berwick's death at her hands. He later questions Ymir about it, and she states she doesn't remember doing it. Bertolt accepts her apology, stating that she probably didn't want to eat anyone.

Trivia

 * In the volume revision of Chapter 47, Berwick's name was changed to "Marcel" (マルセル).
