Eren Jaeger

Eren Jaeger is a boy in the walled town of Shiganshina who dreams of the world beyond it, chafing against a life he sees as caged. When titans breach the wall and tear his home apart, that restlessness curdles into a single, burning vow: to wipe every titan from the earth.

Kaji plays him with a raw, almost embarrassing sincerity — all clenched jaw and shouted conviction — that makes his fury legible as grief rather than bravado. The show hands him an impossible goal and lets his single-mindedness be both the thing you admire in him and the thing you should worry about.
