Okay, I see Mammon as a guy. If you don't agree, I'm sorry. You can just ignore this one-shot. Though it's a friendship one-shot between Mammon/OC/bel nothing more. I actually have two I'm writing now (Spanner and Hibari) but this one just came to me and demanded I write it.
Nicola glared at the old photo in her hands. Her own blue eyes stared back at her shining brightly, a bright grin lighting up her face. The annoying bratty prince, who she wouldn't trade for anyone in the world, stood beside her in the picture. His arm carelessly placed over her shoulders, he was also grinning at the camera. It had been taken when they were both sixteen, so his hair was shorter and much tamer than it is now. She recalled he was laughing while the picture was being taken. Nicola's eyes widened seeing drops of water fall onto the framed picture. Slowly she reached towards her face, touching just under her eye. She's crying? Her eyes scanned the picture and focused on the last person. A small infant rested in her arms, pouting at the camera. The hood covering his eyes had always annoyed her, if he were to come back to them she'd make a point never to complain about it again. Belphegor, Mammon, and Nicola, the three of them were close, closer than any of the other Varia members. Her face suddenly twisted into one of fury. "You bastard! You can't just break our plans like that!" She tossed the frame to the other side of her bed, laying back on the bed she remembered her last moments with the mist arcobaleno.
Nicola laid back on Belphegor's bed, while he rambled on about the mission he'd just had. She wasn't exactly listening to him, opting to play with one of his knives instead.
"The peasants didn't stand a chance against a prince." Nicola resisted the urge to roll her eyes at the prince. Before the prince could continue his interesting story, which was mainly him complaining about the peasants; Mammon decided to enter the room.
"Ushishishi a peasant should knock before entering a prince's room." Belphegor spoke carelessly tossing a knife at the arcobaleno.
"Belphegor!" Nicola nudged him in the side with her foot, seeing as he wasn't too far from her sitting at the foot of the bed.
"I came to get the money you owe me." Mammon ignored the complaints from the prince and instead spoke his reason for being there.
Belphegor grinned at Mammon before throwing another knife. "The prince doesn't owe anyone."
"You going somewhere Mammon?" Nicola questioned.
"Mission." His reply was vague causing Nicola to sit up on the bed.
"You'll be back next week right?" She frowned at him. "The three of us have a reservation at our favorite restaurant." Seeing Mammon's frown deepen she rolled her eyes. "You know I'm paying." That greedy bastard, not that she expected anything different. That's what made Mammon, Mammon.
"Yes, I'll be done by then."
"Promise?" It was a bit childish, but it was also part of who Nicola is. Nobody had broken a promise to her before, then again it's only ever been Belphegor or Mammon who was made to promise her, and it usually had to do with their safe return. Of course they were Varia so it was hidden under something else, this time a dinner reservation.
"Mu." Nicola shot Mammon a look, while Belphegor let out his annoying laugh again. If they could've seen Mammon's face he probably was rolling his eyes at their childishness. "Promise." His tone was dull, regardless it pleased Nicola.
"Lying bastard." Her tears were falling freely now at the memory. "You aren't suppose to break promises." Her voice was weak as she whispered softly to someone who was no longer there.
"Ah. Senpai, that hurts." Nicola wiped her tears hearing the newest member's mono tone. She had hated him at first, though realized how childish she was being she let go of the grudge she had against him for replacing Mammon. It wasn't like it was actually his fault anyway. Fran wasn't as horrible as she had originally thought. Though it seemed Belphegor hated him regardless.
Making sure her tears had stopped, Nicola stood up heading towards her bedroom door. Might as well stop the prince before he actually manages to hurt Fran again. She paused before opening the door and glanced back at the framed picture on her bed.
"Well fine, since you are extremely late I'm going to take Fran with me and Bel instead of you!" She mockingly glared at the picture, before smiling brightly and heading out the door to get to her reservation.
