Petra

A young man with dark hair and a white scarf stands against a stone wall, his expression shifting from serious to slightly downcast. The scene cuts to a young woman with blonde hair and a similar scarf, holding a wooden staff and smiling gently. The sequence then shifts to a forest where a massive, nude Titan with spiky blonde hair is crouched among the trees, its body partially obscured by foliage, as a voice calls out "Petra, now!" and the Titan begins to rise.
