Casshern Sins

A character with spiky black hair and a white and red outfit is shown in a close-up, then the scene cuts to a figure in a dark, ornate suit standing before a crowd of shadowy figures with glowing eyes. The character in the white outfit is then seen falling through a dark, watery environment filled with skeletal remains, before the scene cuts to a close-up of their back and then to a large, multi-limbed creature with long, curved appendages standing amidst the skeletal debris.
