"These blood red eyes don't see so good, but what's worse is if they could… Would I change my ways?"

…

"Squa-Senpai," The 18-year-old Fran droned to his longhaired commander one evening as he walked into the living room to find him sitting with Lussuria and Levi.

"What, brat?" Squalo grumbled.

Fran was rubbing the top of his head. "Bel-Senpai has been extra pissy lately," he complained, having just received a sharp blow to the head from Bel in passing.

Squalo snorted. "Wear your damn frog hat and he won't get so mad."

Fran slumped. "Give me a new partner," he whined. "Before he turns me into Swiss cheese."

"No way," Squalo said. "Your talents work best together."

"Not lately," Fran grumbled. "Do you know how many times he's messed up during missions in the last few months? I nearly lost an eye when he mistook me for an enemy!"

"Hmm," Lussuria hummed thoughtfully. "Bel-chan has been acting pretty distracted and grouchy recently. I wonder what's up?"

"Period?" Levi offered up.

Squalo rolled his eyes. "No one can ever tell what that spoiled little prince is thinking," he said. "But he's been having a lot of migraines lately."

"Why?" Fran asked.

Squalo shrugged. "How should I know? Just deal with it, brat," he said impatiently.

"Poor Bel-chan," Lussuria said, frowning. "He's been suffering from migraines ever since he was a kid and it always makes him really sick."

"Maybe it's a brain tumor," Fran said hopefully.

"Oh, don't say that, Fran-chan!" Lussuria cried. "You like Bel-chan!"

"Like isn't even remotely the word I would use-"

"Look," Squalo said with irritation. "I know Bel is missing a marble or two-"

"-Or ten-"

"-But he is a genius and you seem to be the only one that can keep his 'Ripper' side to a minimum."

"But Squa-Senpaiii-"

"Voi! Just take your next assignment and go away!" Squalo yelled. "There's a new mafia family forming and they're stepping in on our territory. You are to eliminate their boss and anyone else that gets in your way. You guys are leaving tomorrow."

Fran groaned dramatically, just managing to catch the folder hurled at him and shuffled out of the room. He went to go find Bel, making sure to slide his frog hat on before he went into his bedroom.

"Go away, toad," Bel snarled from his bed.

"We have a mission," he said, easily sidestepping the knife thrown at him.

"Not now," Bel grumbled, rubbing at his eyes beneath his bangs. "I have a migraine."

"You always have a migraine these days," Fran said, inching closer to him.

"Che," Bel grunted, throwing another knife at him.

Fran didn't even have to dodge this one. "You missed, Senpai," he pointed out helpfully.

Bel growled and threw another one, but this one missed too.

"Wow, you must really have a headache," Fran said. "Your aim is way off."

"Fuck you," Bel hissed, turning onto his side and curling up.

Fran frowned at him as he tossed the mission folder onto the bed. "I'll let you read over this alone then, Belbina-Sama," he said. "And don't cut up the folder this time."

Bel threw another knife without even looking and this one came much closer to skewering him. Fran's frown deepened as he left the room. The nickname Fran had taken to calling Bel when he was extra grumpy or spoiled usually got him riled up, but there was hardly a reaction this time.

What the hell is wrong with Senpai?

Fran gripped the sides of his seat in fear as Bel swerved around a car in a busy intersection the next night.

"You're going to kill us, Senpai," he said, his steady voice masking his alarm.

"Shut up," Bel said sourly, his head still throbbing and shoving a few pain pills into his mouth.

They were lost. Go figure. Bel had no sense of direction and Fran didn't know how to read a map. This mission was off to a bad start.

"We're looking for a street called Mable...? Wait- Maplea...? No- Maple…" Fran said uncertainly, trying to read the mission's notes. "I told you not to slash these up…" He glanced up. "Ahh… You just passed it…"

"What?!"

"Why didn't you read the sign, Senpai?" Fran droned, nearly hitting his head on the dashboard as Bel slammed on breaks.

A few horns blared behind them and Bel yanked their car around, tires squealing.

"It's your job to read the signs!" He yelled.

"Why can't you read them?"

"I'm fucking driving!"

"You can't do two things at once, Senpai?" Fran said. "How stupid are you?"

Bel had a knife pressed against his throat in seconds and he hissed quietly as the blade nicked his skin.

"I'll kill you," he snarled.

"Or you could pay attention to the road," Fran said dully and Bel looked up in time to swerve around another car. "There's Maple Street," he said pointing.

Bel turned down the right street, cutting off a few people and receiving a few middle fingers in return.

"Which building?" He demanded.

"Let's see…" Fran said slowly, checking over the torn notes again. "That one, perhaps?"

Bel screeched to a halt in front of the building and got out. "You better be right, Froggy," he grumbled. "Or I'm about to go on a killing spree in the wrong place."

"Well, wait a minute!" Fran cried. "And you're parking illegally! Can you not read this sign either?!"

"The prince can do whatever he wants," Bel said, turning on his heel and marching towards the building.

Fran scrambled after him as Bel burst through the front doors.

As discreet as ever, Senpai…

Bel made quick work of the guards on the first floor and Fran followed him through the halls, letting the prince do all the work. He wouldn't dare bother Bel when he was in his element, less he risk a few fingers, guts, or eyes. Those just weren't the types of things he kept spares of.

They made their way to the top floor, leaving a trail of blood in their wake and Bel kicked the doors down to the boss's office. Fran held back as Bel dodged the two guards waiting for them and sunk his knives into their throats. Bel giggled happily, appreciating the gurgling sounds they made as they slumped to the floor.

"Now…" Bel said, grinning as he saw the boss cowering in the corner of the room.

He approached the man as Fran stepped over the fresh bodies, careful not to get his shoes wet in blood. It was such a pain to wash out!

"Please, don't kill me!" The boss sobbed. "I'll give you anything you want!"

Fran sighed.

Great… Another wimp. Don't these guys know who Senpai is? Their tears only make him want to slaughter them more.

"Shishi~ That's-" Bel froze as his leg caught a tripwire and they were thrown into chaos.

A flashbang went off and they were both temporarily blinded. This certainly wouldn't help Bel's migraine. Fran covered his ears, cringing at the terrible ringing in his eardrums. He stumbled backwards and tripped over one of the bodies.

"Wah!"

He landed on the floor, splashing in the pooling blood.

Damn it!

It was a few minutes before he could make things out clearly again and he saw Bel bent over, clutching at his head in agony. He clambered up, slipping a little as he walked over to Bel.

Fucking mess he always makes! It's in my boots!

"What the hell was that?!" He cried, ears still ringing and pointing a bloody finger towards where the boss used to be. "You let him get away!"

Bel snarled. "I fucking know that!" He yelled, still holding onto his head.

"How did you not see the wire?!"

Bel shoved past Fran and left the room. Fran grumbled as he squelched after him. There was no sign of the boss anywhere and the two of them were eventually forced to give up.

"He's long gone by now," Fran said dully.

A string of curses spilled from Bel's lips as they left the building in the darkness only to find that their car had been towed.

"There goes our 'borrowed' car..." Fran sighed. "I told you we couldn't park there."

"DAMN IT!" Bel snarled.

"Now what?" Fran asked, craning his neck to see how much blood he had smeared over his backside.

"We walk. Ditch the jacket," Bel growled. "How did you even get like that?"

Fran glared at him as he shucked his jacket off and tossed it in a dumpster.

How the hell have I managed with you as a partner all these years?

"You're buying me a new one," he said as they stalked off into the night.

Bel just scoffed at him and they went to find a hotel to lay low in for a while.

…

"Why doesn't the genius prince just go find the guy so we can go home?" Fran mumbled as he tried to scrub his pants clean in the sink. He peaked out of the bathroom to see Bel curled up on one of the beds, facing away from him. He frowned at his unresponsive form. "Belbina-Sama?"

Bel gave him the middle finger and Fran walked cautiously over to him.

"How's your head?" He asked tentatively.

Bel grunted, as he clutched his bottle of pain pills to his chest like a lifeline.

"Don't take too many of those," Fran warned him.

Bel glanced at him through his bangs and gave him a once over. Fran was in his dark t-shirt and boxers, hands stained in the blood he fell in. Bel could feel his cheeks turn slightly pink as he gazed at Fran's thin, pale thighs. He forced himself to look away.

"Do you have a plan?" Fran asked him, oblivious to the wandering eyes.

"Just give me a little time," Bel groaned. "I'll come up with something."

Fran watched him for several minutes, the exposed part of Bel's face looking pale and clammy. He sighed and left the room to retrieve some ice and came back to wrap it in a towel. He handed it to Bel who frowned up at him.

"Take it," he said.

Bel reached up with a slightly shaky hand and took it. "Thanks…" He mumbled sulkily.

Fran smiled as he went back to finish cleaning the blood from his clothes. He hung his pants out to dry when he was finished and gazed over at Bel who had stripped down to just his boxers with the towel of ice resting over his eyes. Fran blushed, his own eyes scanning over his Senpai's form. He could see a thin sheen of sweat over Bel's chest and he wondered briefly if he was feverish. He couldn't tell if Bel was awake or not, so he turned out the lights and went to bed.

…

Fran awoke later in the night to hear Bel stumbling through the darkness towards the bathroom. He winced as he heard him throwing up and he shifted restlessly, knowing he couldn't help him. Bel kept himself locked in the bathroom for the rest of the night and Fran could occasionally hear the sounds of more retching.

…

Fran awoke again in the morning, not remembering even falling back asleep and he sat up, rubbing at his messy hair. He found Bel back in bed, curled up under the blankets and he could just make out Bel's closed eyelids through his bangs.

Did he get any rest last night?

Bel snuffled and twitched in his sleep as Fran slid quietly from bed. He got dressed, displeased to find his pants weren't fully dried as he put them on.

I should have brought a spare set of clothes, but this was supposed to be a simple assassination mission! Kill and go home, damn it!

"Stupid Bel…" He huffed as he left the room to go find breakfast.

Bel began to stir when Fran came back a little while later and he sat up, clutching his head.

"Still bad, huh?" Fran said, handing him a bottle of water.

"Nn… Slightly better," he said hoarsely, taking a few more pain pills.

"You should eat something," Fran said. "I'm sure you spewed out everything your stomach had to offer last night."

"No food," he said, pinching the bridge of his nose with a pained grunt.

"But I brought you a banana muffin~" Fran said, holding it up. He could see Bel's interest peak and he grinned.

Bel's two weaknesses in life? Strawberries and bananas… and well- maybe knives too… and his crown… and being a prince… Okay, whatever.

He handed him the muffin and Bel took it only a little reluctantly.

"So have you come up with anything, oh, genius prince?" Fran asked when Bel was finished eating.

Bel laid back against the bed with a tired huff. "Not really…" He admitted.

They both tensed as Fran's cell phone started ringing.

"Ahh, Squalo-Senpai," Fran said as he answered. "Did you miss us already?"

"Voi! Cut the shit!" Squalo roared and Fran had to hold the phone back from his ear. "What the hell is going on over there?!"

Fran gave a dramatic sigh. "So you know already?"

Bel groaned as he turned onto his side, facing Fran. "He's so nosy."

"One of the Vongola's brats reported in about some mess going down in your area!" Squalo said, irritably. "How did you fuck this up?!"

"Mmm… Maybe you should ask Bel-Senpai about that," Fran said, giving him a pointed look.

Bel grumbled in response, blood-red eyes hidden beneath his bangs and Fran wondered briefly when was the last time he'd seen them.

"Then put him on the phone!" Squalo yelled.

"Hai~ Here you go, Senpai," Fran said, tossing him the phone.

Bel jerked back as it hit him in the face and Fran snorted.

"Sorry, Senpai," he said, trying not to laugh. "I thought your eyes were open."

"Ow! Fucking brat! They were!" He cried as he sat up.

Fran paused. "Then why didn't you catch it?" He asked.

"I didn't know you were going to throw it!" Bel said defensively.

"I think that migraine of yours is really dulling your senses," Fran said, grinning.

"Squalo," Bel said darkly, holding up the phone. "I'm going to kill this shitty little toad..."

"Voi! Focus on the mission, Belphegor!" Squalo shouted.

Bel winced, yanking the phone away from his ear as well. "Chill out, Squa. We'll find the stupid boss and tear his guts out."

"Oh, lovely," Fran said, dully.

"You fucking better or Xanxus will be up my ass for this-"

"Pfft-"

"Shut up!" Squalo snarled. "Anyway- That stupid Yamamoto brat said they have a couple of their goons trying to clean up their base before it attracts the police's attention. Go get some info out of one of them so that you can finish your damn mission!"

"Right…" Bel said and hung up. He got out of bed feeling weak and nauseated, his skin still pale.

"Are you sure you're up for this?" Fran asked uncertainly. "You're looking pretty rough…"

"Che. I'm fine," he said as he pulled his clothes on. "Let's just go."

"Are you sure?" Fran said, following him out the door after he pulled his boots on and brushed his teeth.

"I can function well enough," Bel grumbled.

"Could have fooled me," Fran snickered as Bel tripped.

"Fuck off."

Short first chapter, but the rest will be longer.

Belbina… lolz. It's a play on 'bambina,' which means 'baby' in Italian.

Also, I salute all those who have been given the same fate as I to suffer through chronic migraines. It's agony. For those who haven't, just imagine throwing up, passing out, spending absurd amounts of time in the fetal position, temporary blindness, and generally feeling like death. But… So it goes.
