Sensei.. 💔

A man with long white hair and a dark cloak stands with a wide, toothy grin against a starry blue background, then the scene cuts to a young man with spiky blonde hair and a headband looking determined in a grassy field, followed by a shot of him from behind as he walks forward with the white-haired man, then a distant view of the blonde man walking away across a field, then a close-up of the white-haired man's face with a calm expression, and finally the white-haired man is shown falling backward in a dark environment with the word "arizu" overlaid.
