(time to start, eh??? and yes, Diavolo chibi pic because- just because i said so- and yes, in-rp chat also because i said so, and yes- long reply- still because i said so- i warned you i felt like typing quality responses-)
Diavolo hummed an uninterested tune to himself, sitting keenly at his desk with papers piled as high as his eyes could follow, blandly flipping through them as if he were on autopilot. He understood that ruling Devildom came with a hellish amount of paperwork, but he didn't think a good portion of it would be passed down to the prince! He had school papers to go through too, nonetheless. It didn't seem like Barbatos was going to let him leave his room until he was finished, either, which just added salt to the already metaphorically open wound.
Though, while the prince's mind was on the topic of school, maybe he could rope one of his classmates into helping him out. None of the angels would willingly do so; he knew that much from Luka; but perhaps one of the fellow demons would oblige. He [i would] ask Lucifer, but the eldest demon seemed to hate him at the moment, Satan was glued to his side like he was a reverse version of the plague, Mammon was instantly out of the question, and Beelz usually required food in return for help, which was something Diavolo didn't have at the moment. Which left Asmodeus; though, frankly, Diavolo didn't want to even [i imagine] what he'd have to do in return as a 'favour'; Leviathan; who was probably busy gaming; and Belphegor.
Belphegor! That was somebody Diavolo hadn't talked to in a few days, and he was who didn't seem to utterly despise; or was addicted to; him either! Perfect! Now all the prince had to do was find a way to sneak past his butler, which was no easy feat. Scooping up a pile of the papers littered about on his desk, Diavolo quietly tiptoed to his window and pried it open, keeping his eyes glued back to his room's door in case it opened. When he was sure he wouldn't get caught, he slid out of the window, landing on the ground with a soft thud. He swiftly scurried his way through the Devildom grounds until he got to the seven brother's mansion, snickering to himself the entire run there. He would surely get scolded for this later; or even by Lucifer if the eldest demon out of the seven caught him; but he couldn't care less. He needed a little help, so he was going to get it.
Diavolo poked his head through the front door of the mansion, checking to ensure the coast was clear before skittering inside. He made his way through the familiar halls, going as far as hiding when needed to avoid being seen, before [i finally] making his way to Belphegor's room. Praying to whatever fictional demon might be of a higher rank than his own royalty, he softly knocked on the door, hoping that the sleepy, sloth demon would actually be [i inside] his room for once.
"Hey, hey! Lemme in, before Barbatos or Lucifer catch me!" Diavolo whisper-called out, shifting awkwardly in front of the door with his stack of papers, frantically looking around to ensure he wouldn't be seen standing at the door by anybody.
