Hello Peeps! This is my first time confidently writing about this fandom, and I start it with a set of one shots. (I must be crazy..) This is supposed to work like an Advent calendar. One story a day. I know the look you're giving me right now. Don't worry, I did it before with another fandom.

I am not into the fandom for too long, so I don't know as much as other people might. (Most of my knowledge comes from the wiki) If there is anything wrong with how I portray events, I apologize for that in advance. Also; I love to make up things. I will try to make these one shots happy and light hearted, but past experiences showed me that it's hard for me to pull off happy stories. Don't judge too hard!

Also, since To Aru Majutsu no index is taking place mainly in Japan, I will try to make it seem more authentic by actually going into weaboo territory and adding the honorifics to names, etc. I usually hate doing this, however this time it's a story that really takes place in Japan, so it should be alright.

One more thing: English is not my native language, please look over my terrible grammar and the constant typos :3 (I'm trying my best.)

I love reviews and would like to hear what you liked about the story and what you think I could improve!

DISCLAIMER: I do not own To Aru Majutsu No Index or Any of the characters. I just borrowed them and played around with them.

Something about the warm and comfy feeling surrounding him felt off by a lot. He had been sleeping on the couch again, exhausted from the walk to the grocery store and back to the apartment and had hoped to be left alone at least for a few hours. When faint wind brushed over his head he woke up. Someone had bothered to put a blanket over him, the TV had been turned off and loud, trampling footsteps could be heard as a high pitched and awfully annoying voice echoed in his hears.

"It's snowing! Misaka exclaims as Misaka rushes up to the window to take a look!"

He sighed deeply and opened his eyes. There was no way he would be getting any more sleep now so he sat up and shoved the blanket away. It was a light shade of rose and had simplistic bunny shapes printed all over it. This was obviously Last Order's blanket. A look around told him that he was currently alone with the girl. Yomikawa usually sat at the dining table and read a book or had paperwork to go through when she was there.

"What are you getting excited about, It's just snow." He growled into the direction of the brown haired girl as he turned and looked over the backrest.

The girl instantly turned towards him and pursed her lips while she crossed her arms. "Misaka has never seen snow before! Misaka explains as Misaka tries to hide the truth that she has seen more snow than she could comprehend."

He clicked his tongue and turned back towards the coffee table. "It's just frozen water. Besides, you've seen so much of it already, why aren't you bored of it yet?" He muttered as he tried hard to make it sound as boring as possible.

"Misaka wants to go out and take a better look, Misaka says as Misaka completely ignores you."

He lifted an eyebrow at that and turned to look outside the window again. "It's melting right away."

"Misaka wants to go out anyway! Misaka complains as Misaka tries to sound angry." To emphasize her words she stomped a foot on the ground.

Her pink slippers somehow didn't fit with the rest of her outfit that consisted of gray sweatpants and an oversized white pullover. Her hair was parted into two mismatched ponytails and decorated by colorful hairclips.

"What's with that outfit, shitty brat?" he spat and completely ignored her protest.

The girl seemed insecure for a moment but quickly reverted back to her cheerful self and pouted even more. "Yomikawa-san bought hairclips for Misaka, but Misaka didn't want the other hairclips to feel lonely so she put in all of them, Misaka tries to explain as Misaka feels sorry for the left behind hairclips."

He stared blankly at her for a second, then he shook his head and rubbed his temples.

"Does your head hurt? Misaka asks as Misaka rushes over to you." The girl quickly appeared by his side and looked awfully worried.

"Yeah, you're making it hurt with your shitty logic." He growled at her and finally stood after he had located his crutch on the floor.

They had spent so much time together now, yet he still couldn't understand her at times. The things they had said to each other, the stuff he did, it seemed meaningless now. Words uttered in desperation while both of them were at their limits.

"Nee, can we go out and watch the snow? Misaka asks as Misaka clings to your arm."

As said, the girl clutched the sleeve of his free arm and used all of her weight to keep him from going any further. That resulted in him losing balance and he crashed into the floor, barely able to evade the girl. He cursed under his breath as he sat up again.

"How many times have I told you to stop that, Shitty brat?!" He yelled at her, his face full of anger that would make anyone back away in fear. Anyone but this girl, who didn't seem to be bothered by it in the slightest.

Last Order simply walked past him and threw a jacket onto him. "Get dressed, we're going out. Says Misaka as Misaka tries to impersonate Yomikawa-san."

That kind of behavior didn't help his mood at all. "Like hell." He hissed and got back to his feet, ignored the white jacket and headed to his room.

Sitting on his bed he ran a hand through his hair and got his hand stuck on something. Frowning he tried to get it out, glaring at the oversized flower hairclip that had somehow found its way into his hair. Last Order probably had a lot of fun sneaking up to his sleeping form and putting the clip into his hair without him noticing. He shook his head as he put it on the nightstand and threw himself into the pillows.

He was dozing off again when he suddenly heard music. It was the terribly cheesy music that Last Order had found a liking to. At least it weren't Christmas songs- He cursed when the music stopped and started again with a loud blaring Christmas hit that he had heard so often that he could sing along if he wanted. He couldn't understand what the girl found so interesting about that holiday. He couldn't even remember if he had ever celebrated it. Who was there to celebrate it with anyway?

He flinched when the door to his room suddenly flew open. "Accelerator!" Last Order yelled at him, her face angry. She had a book in her hand, upon closer look it appeared to be one about complex mathematics. "Misaka does not understand this book at all! Misaka complains as Misaka tries to hide her anger!"

The Christmas song was still blaring, the girl was still wearing this terrible hairstyle and she waved the book around impatiently.

"So what?" he growled back at her. "Go back to whatever you have been doing and leave me alone."

She crossed her arms. "Misaka will not leave until you explain this book, Misaka says as Misaka tries to bargain."

He sat up. "Why do you want to read that book anyway?"

Her cheeks turned red in embarrassment. "Yoshikawa-san said it's too difficult, So Misaka wants to read it and show her that she has been wrong! Misaka says as she tried to laugh evilly." The girl pretended to laugh in a manic matter and made the level 5 in front of her shake his head. Slowly he got up again and took the book out of her hands when he passed her.

He truly had considered to explain the book to her, until he saw the mess the living room had become. Paper was sprawled over the floor, a cup with cocoa was lying on the coffee table, the brown liquid spreading over it. Cookies were lying on the floor and colored pencils could be found everywhere in the room.

"Yomikawa is going to kill you." Accelerator hissed when he eyed the mess.

"Nope. Misaka says as Misaka grins. She will kill you for not looking after me."

He lightly hit her head with the side of his hand. "Clean that up!" he ordered.

After the girl had finally removed the mess while pretending to cry, she sat down next to him on the couch and shoved the book over to him.

"How come you don't understand this shit anyway?" he asked her after a while of uselessly trying to explain something that seemed incredibly easy to him.

She glared at him but stayed quiet, until he made the next remark. "Even a brainless idiot could do that." He sighed deeply.

"Oh yeah?! Misaka yells as Misaka has an evil plan entering forming in her mind" Her glare got more intense when she suddenly jumped on the couch and disconnected him from the MISAKA network. The book dropped out of his hands and he glared back at her.

'Asshole, brat!'

He could only continue to glare while Last Order smiled cheerfully and leaned against him.

WORST seemed to have more of an impact than he would have dared to believe.
