Attack on Titan: Part 1 – Guren no Yumiya

Attack on Titan: Part 1 – Guren no Yumiya is a compilation film that recaps the first half of Season 1 (Episodes 1-13) with theatrical animation quality. The film condenses the early events of the series — humanity behind the walls, the Titans' initial breach, Eren's transformation, and the beginning of the Battle of Trost — into a single viewing experience with improved visual quality compared to the original broadcast. The compilation was created partly to bring new viewers up to speed before Part 2's release and to serve as a theatrical experience for fans who wanted to revisit the series' beginning in a cinematic format.

This compilation film is purely optional for anyone who has already watched Season 1, as it contains no new story content. It is a re-edited and visually polished version of existing material rather than a unique narrative work. However, for viewers who are new to Attack on Titan and prefer cinematic presentation over episodic format, or for fans who simply want to revisit the iconic beginning — Eren watching the Colossal Titan's first appearance, the charge of the Survey Corps, the Titans' terrifying scale — the film provides that experience with enhanced animation sequences in key moments.
