Stay night

A character with blonde hair and green eyes stares forward in a dark, geometrically patterned room. The scene cuts to a silhouetted figure wielding a chain weapon against a swirling sky, then to a small, horned figure holding a staff on a hilltop at sunset, followed by a lone figure running across a vast, colorful landscape, then to a close-up of glowing eyes beneath a red hat, and finally to a swirling vortex of yellow and orange light.
