"Angle of Death" or "Devil in Disguise"

Mitsuru Kotone is a corporate slave cursed with an unfortunate flow of bad luck. His boring, solemn days and the piercing voice in his head suddenly become worse after witnessing and accidentally recording a murder. The sight of the murderer was mesmerizing but that didn't stop him from running and fearing for his life after being spotted. He decides not to report the video because evidently, his shitty boss is the one who died and the "angle" his coworkers talk about is the one who did it. For Mitsuru, it's not a matter of if he will run into the murderer but a matter of when. A race to see who kills him first, the voice in his head or the "angle".
