Shalnark is 25, and you're 16

You were walking around Meteor City when you suddenly heard what sounded like a fight. You followed the sound, and when you saw what it was, you froze. It was your older brother, Shalnark, and a former member of the Phantom Troupe, Hisoka. Shalnark saw you out of the corner of his eye, and turned his attention to you. His eyes widened when he saw that you were there. Hisoka looked at you too and smirked before he took out his main weapon, one of his cards Shalnark: (Y/N), get back! It's too dangerous!
