I'm going to enlighten you on what the bell Nightwalker carries around with him
Every day items: 1 katana, 6 bombs that do various things, 1 glock strapped to his leg, hidden blades like in assassins creed, a few ninja stars and throwing knives, and 2 regular knives.

Mission items: 3 katana, 12 bombs that do various things, either a desert eagle or a silence flock strapped to his leg, hidden blades, more ninja stars and throwing knives than usual, and some of that extremely sharp string.
Not to mention he a magician and hides it all under his clothes....jk it's all collapsible.
