Milo Nekoyanagi and Bisco Akaboshi from Sabikui Bisco HD Wallpaper

Two young men with distinctive hair colors stand on a railway track. The one on the left has blue hair and a wide smile, carrying a large backpack. The one on the right has red hair and a determined expression, wearing goggles. Strange green orbs float in the air, and a large, whale-like creature is visible in the sky.
