A hot night followed the hot day, and I stayed sprawled out face-down on my bed, enjoying the feel of artificially cooled air against my back. In the room next to mine, my brother was probably pouring over the homework he had received from his extra classes with his friends. I would offer to help them, if it wasn't a part of the story and didn't take me away from the air-conditioned bliss of my room.

Music was pumping through the space, rendering me unable to hear anything, including the knocking on the bedroom door. Whoever was knocking must have gotten impatient, and opened the door.

They promptly stumbled back as the full volume of my music hit them. My head was still buried in the pillows so I didn't know what had just transpired. It was only when my music was abruptly switched off that I deigned to lift my head and give attention to whatever was happening.

"Goddamnit, woman! Don't play your damn music so loud!"

I slumped my head back in my pillows and mumbled, "Close the door, you're letting the hot air in, moron."

"Who are you calling a moron?!"

"Gokudera-kun, calm down. We're here to ask nee-chan a favour, remember?"

"Tch."

"Um, nee-chan?"

I sighed, and turned over to face them.

"Yes, Tsuna, what is it?"

Tsuna was rubbing the back of his head sheepishly.

"We, uh, we really need your help on this one question."

I sighed again, and dragged myself off the bed. Then I draped myself over Gokudera's shoulders, much to his irritation.

"Get off me, woman!"

"No can do, moron. Tsuna's too short to carry me, and you're the only other one here."

"Gokudera, just go along with it." Tsuna pleaded. "Please?"

Gokudera was clearly fuming, but said, "Tch, fine. But only for you, Juudaime."

We made our way out of the winter wonderland that was my room and into the sweltering hell that was Tsuna's. When we had successfully entered the room, Gokudera shoved me off him and I flopped down onto Yamamoto.

"Now, now, you shouldn't treat women so roughly, Gokudera-kun."

"Yeah, Gokudera-kun."

"Why does it sound so insulting when you say it?!"

Tsuna tried to defuse the situation before it blew up even more.

"Nee-chan!" he said, trying to turn my attention to him, "Do you know the answer to question 7?"

He tried to hand me the sheet. I sat up, cross-legged, and held up four fingers.

"Payment."

"Eh? Four? Four what? Forty thousand? You want forty thousand yen?" asked Tsuna in disbelief.

"That would be nice, yes."

Gokudera snapped and growled at me.

Pointing, he yelled, "Forget it, woman! Keep your answers, we'll figure it out ourselves!"

I gave him a strange look, but shrugged, and said, "Fine by me. I'll leave you to it then."

I lay down on the floor and rolled under Tsuna's bed. The other occupants of the room stared after me.

"Nee-chan," inquired Tsuna, after a moment, "What are you doing?"

"Looking for porn."

"What?!"

Sticking my head out from under the bed, I huffed in disappointment.

"Not to say I didn't expect it, but there's absolutely nothing under here except for a few dust bunnies. Are you sure you're a boy going into puberty? I'm sure Mum gives you enough to buy a few magazines here and there."

"Woman, are you suggesting Juudaime isn't manly?!"

"You said it, not me."

"You-!"

Yamamoto held Gokudera back from stomping my face into the ground, as a mortified Tsuna buried his face in his hands.

"Calm down, Gokudera-kun. I'm sure she was just teasing. Let's get back to work now, shall we?"

Gokudera was still seething, but sat back down to do work. I entertained the idea of enraging him once more by casually pointing out how willing he was to listen to Yamamoto's words, but decided the story had waited long enough and ducked back under the bed, intending to spend the entire study session there.

Haru arrived, Bianchi passed, and finally Haru's mathematics' professor father came to help. His answer was wrong. Reborn spoke up.

"No, that's wrong. Nee-tan had the right answer."

Oh look, he's adopted me.

"Eh? What do you mean, Reborn-san? She didn't even read the question."

"You'll see."

Looks like I had no choice. I re-entered the study session by poking my head out from under the bed and surprising the Miuras.

"Yo."

"Hahi! Onee-san, what are you doing under there?"

"Looking for-"

"Nee-chan! Just please tell us the answer to the question!" begged Tsuna.

"Fine." I huffed, and held up four fingers. Gokudera blew up at me again.

"We're not going to give you forty-!"

"No, dimwit, the answer is four."

I turned to Haru's father.

"You made a mistake on the foxtail formula."

The man peered more closely at the question, obviously redoing his mental calculations. He blinked, surprised.

"You're right! But," he frowned, "How did you know the answer, if you hadn't even read the question?"

I withdrew back under the bed, leaving just my eyes visible.

"I know everything." I whispered in an eerie voice. Everyone just stared at me. I sighed, and pointed up at Reborn's hammock.

"Just look at his sideburns already."

The mathematics professor did so, and his eyes lit up in recognition and hero-worship.

"Boreen-hakase!" He started fanboying, and I used the opportunity to slide out from under the bed and rush back to the cool of my own room.

...I still can't believe Tsuna doesn't own any dirty magazines. Maybe I should change that.

Some time later, Tsuna was yet again woken Vongola Style™ and fell off his bed in his panic. As he hit the floorboards, he noticed something residing in the previously empty space under his bed. It was a stack of magazines featuring women in tight and skimpy clothing.

"NEE-CHAN!"

(He yelled again, even louder, when he accidently knocked the stack over and found a few featuring nude men.)

(The Sawadas had a bonfire that day.)

I had a lot of fun writing this chapter. Like, a lot.

To Yoshihiro143612: Yes. The power of love. I swear I wrote this entire series just to make that one joke.

Thanks for reading. Hope you enjoyed. Tell me if there's anything you particularly want to see.
