Takeroy

A dark-haired anime character in a suit covers his face with his hand, then the scene shifts to a spiky-haired character adjusting his earphones in a school hallway, followed by a white-haired character in a hooded jacket looking determined, then two characters standing back-to-back against a cloudy sky, and finally a close-up of a character with wide eyes in a blue hood. The sequence takes place in various settings including a dimly lit alley, a school corridor, an industrial area, and an open landscape.
