Backstory

 At a young age, Dani had a good childhood spent around lots of family. It was only a few years later while living in Gehenna that their life began to slowly fall apart. They were never told why their relatives never visited or called anymore, or why mom and dad had to begin working more hours.
 To Dani, it was beginning to feel like they've spent more time with babysitters and stray animals than their own parents. Both mom and dad would get up early in the morning, drop them off at school, then come home late at night, cook dinner, then head straight to bed. Seeing how they've become practically like zombies made Dani want help brighten up their day, even if it's just for a moment.

 It was when Dani began telling lies that caught their parents' attention. The puzzled look on their faces and then their laughter after Dani confessed it was a joke made them so happy, so they kept doing it. At first, their parents played along with their silly stories, but it died out as quickly as it started as Dani's stories became more and more elaborate. Seeing their parents completely ignore them broke their heart, so Dani was motivated to find another way to get their attention again.
 Dani grew inspired by a few cartoons to try and replicate some pranks. At first it was harmless things, like fake bugs. It was fine for a while, but then mom and dad got tired of that too. So it became chocolate powder in the shampoo bottle. And mud all around the toilet. And tape covering the remote. They began yelling at Dani for all the inconveniences they were causing, telling them they're annoying and should stay out of the way. But Dani noticed that time passes during it. That the 2 hours of mom and dad yelling still counted as them spending time with them.
 Dani wanted more of their parents' time.

 Dani's pranks began getting more and more creative as time went on. No matter how many times Dani gets told that they're a failure and won't amount to anything, Dani only thinks it's because the 'joke wasn't good enough'. So they have to try harder to make their parents laugh. But there was never any laughter, and Dani's punishments got harsher. But it's okay, because when jokes Were funny, Dani's parents would apologize and buy them long sleeved shirts.
 Nail-polish coated soap bars. Lubricant-filled soap bottles. Itching powder coated toilet paper. Alarms set to go off at once. Then their best one yet: Snapbang fireworks under the toilet seat. That one was definitely one of Dani's bests. Their parents let them know exactly how they'd felt about that one.
 Dani was unsure if they should ever try to top that. At least, not towards their parents anymore.

 Now Dani has an easy ticket to make their face known across Gehenna, but.. they're unsure how they feel about it. Their parents were equating them to a slasher movie villain. Sure those are cool and all, but Dani doesn't recall doing anything That bad. Dani was also unsure why their parents were quick to tell others that Dani's coverings were their own fault. But mom and dad gets angry if Dani tries to correct them, so they guess it's their turn to play along.
 Surely their parents love them still, and didn't mean all the horrible things they've said. They always apologize after and buy Dani a lot of the things they want, so it's all good.
