This short voice clip captures Shizuo Heiwajima snapping out a single frustrated word in a clipped, forceful delivery that lasts just under seven seconds. It feels instantly exasperated and blunt, like a reaction to bad news arriving at the worst possible moment. The line comes from Durarara!! episode 7, where Shizuo's short temper drives the outburst.
