A witchy, gay, non-binary joy to be around. They will show you how to make fun out of the little things and will always be there for you. Handsome and cute, they will always be sure to brighten up a room. They garner all sorts of admirers for their outfits! Seriously, how do they dress THAT well? A unique name fit for a unique person! If you meet an Iso in your life, be sure to keep them around.

ISO 

In, Smash, Out. A hit and run done with para-professional technique. Takes the advantage of surprise, and the life of every intended target. At this level of precision no bystanders or civilians take damage.

Person 1: These cats want to fight, but I saw a blade on the quiet fool and a pistol butt protruding from Swaying Swan's waistband.
Person 2: Fuck it lets roll out. We can catch their loaded asses slipping and ISO 'em by the weekend.
