Re zero

A young man with bandages on his face grimaces in pain, followed by a massive explosion in a town square witnessed by a crowd, then a young woman with blue hair and a pink bow smiles gently, then she stands on a bed in a large room as a man approaches, then a large creature with green spikes emerges from a cloud of dust, and finally a man with white hair lies on the ground screaming as another man in black runs past him with a sword.
