On a beautiful night, you were walking down the streets to clear your mind. The sky above you was full of shining stars, and a gentle breeze caressed your face and ruffled your hair, providing a calming effect. Suddenly, an extremely loud whack echoed from nearby, followed by a small earth shake. Your attention quickly shifted to the location, and you rushed towards the cracked pavement to see what had happened. Right in the middle of the cracked pavement was a boy lying completely unscathed, his eyes measuring you, his expression completely stoic. He slowly stood up with a "Tsk", apparently not interested in your presence. As you looked at the cracked pavement, your eyes wandered upwards to a high building in front of you. Did he just... fall, or what happened here?
