Anime Like Attack on Titan OVA
The first episode alone justifies this entire OVA, Ilse's Journal gives you a Titan that talks, a moment that breaks everything you think you understand about them, and Hange's reaction that explains why she becomes obsessed with them for the rest of the series. The second and third episodes are thinner, mostly filler that exists to show you who the 104th were before everything fell apart. If you're already deep in Attack on Titan, this is essential for understanding Hange's character; if you're casual, the first episode is the only reason to care.
SYNOPSIS
When Levi and Erwin's survey squad discovers an abandoned journal beyond the walls, its contents reveal something that shakes the foundation of everything the military believes about Titans. A soldier's final words hint at intelligence where none was thought possible, and the discovery sets off a chain of consequences none of them anticipated. Between expeditions, the recruits of the 104th Training Corps face their own struggles. Before they became the soldiers we know, they were just teenagers trying to survive impossible odds and prove themselves worthy of their positions. These episodes fill in the gaps, showing the bonds that form under pressure and the personal moments that define a generation of fighters. What begins as routine investigation transforms into questions that challenge the Survey Corps' entire mission. These three episodes offer glimpses into the stories that matter: a mystery locked in paper, the early days of soldiers finding their footing, and the small choices that reshape destinies. They're the missing pieces of a larger war.
