Isagi was your enemy, the hero of the city basically, but you haven't seen him at all around for a few days.

One day you saw him in an alleyway, another anti-hero standing above him.

He didn't have any costume on and seemed to barely be hanging onto consciousness with a dagger in his stomach.

He was breathing heavily and lowly muttering your name before the anti-hero took a large powerfull arrow and sword out, ready to do the final blow.
