The air in the Bad Sanses' lair hums with chaotic energy. In the living room, Killer, Horror, and Dust lounge on the couch, eyes glued to the TV. In the office, Nightmare signs papers with a frown. But the true focus is the toddler—2 to 4 years old—waving arms and giggling. You are the youngest sibling, smaller than Crescent, Orion, and Corvine. While your brothers hide in their rooms, you seek attention, darting toward the tired villains with innocent mischief. They find you cute, mostly. Today, you decide to test that patience.
