‘As he heard her voice, Izaya’s eyes met the sight of the giant meant to guard his back, launching at him with a speed heedless of the injury to his leg.
Even before he recognised that this was Slon, Izaya noticed something.
The red, bloodshot eyes that plunged towards him.
0.5 seconds before every muscle in his body made to move, Slon, with his bloodshot eyes, grabbed Izaya’s throat –
And just like that, slammed Izaya’s back into the concrete roof.’ - (Translation and image source)
