A quick A/N: I'm a fan of time loops to the extreme, and after I finished all of Toradora! in 3 days, I had to write some fanfics in the fandom, and I saw there were no looping stories, so I went for it!

This is based off of the basic premise of the Infinite Loops (google it, there's a wiki and a TVTropes page), with a few changes. Due to data corruption, loops aren't limited to a beginning event that always starts a loop. The loop will repeat (from the last time the looper slept) until the series of events plays out 'Right,' e.g. canon events. Obviously, there is going to be a lot of comedy, but there will be an overarching plot, as well.

In addition, the 'fused loops' (think of them as crossovers) will not be occurring anywhere near as soon as usual due to aforesaid corruption, and I'll likely put those in a different story once I'm further along with this.

For in-show dialogue, I'm using the Mirror 2 subs of this. Just to be OCD about small differences in dialogue between subs (or dubs, if that's your cup of tea).

So, without further ado, let the loops begin!

It was a bright, early morning, but inside Ryuuji Takasu's small apartment, it was dim. He stood at his mirror, fingering his recently-cut bangs, scrutinizing them carefully, magazine at his side. It took only a few seconds before he frowned and sighed, "This reeks of fake," and chucked the magazine into the trash.

Unfortunately, his disgusted toss unbalanced the small can, and it toppled over and spilled the magazine and the rest of the trash onto the ground. He sighed again, and knelt to pick it up, but as he did so, his eyes wandered to the wall behind the wastebasket.

On the very bottom, next to the floor, mold was growing. Again. He'd just scrubbed there two days ago! This apartment bred mold like rabbits, he swore as he stood with a groan.

He'd have to get that this afternoon after school. As he stood and opened the curtain, though, his eyes returned to that evil growth of fungus.

…Or he could just clean it now. "Where did I put that rag?" he muttered to himself, searching around in his bathroom. Finding it, he wetted the cloth and began to scrub vigorously at the offending mold. It refused to budge, and he grumbled as he reached for his mold-scrubbing tool (he'd put this one together himself for maximum cleaning efficiency) and rubbed at it once more. A noise caught his ear, and he turned and listened for a moment. Was Yasuko already waking up?

The noises quickly subsided, however, and he returned to the task at hand, scrubbing until all the mold was dead. "Ha!" he laughed, and derisively washed his hands of the filth. "Now for breakfast…"

He hummed a nonsensical little song under his breath as he prepared his breakfast and Yasuko's, wrapping hers carefully before eating his. He tied up the trash and moved out to the main room, messy and strewn with clothing.

The bird cage hung in the corner was still silent under its covering, and he berated it, "Inko, you're still resting? It's morning already," while he cleaned up.

He moved over to the veranda doors, picking up as he went, until a pair of legs unexpectedly grabbed his own as he was moving and bending down to pick up his mother's purse.

Not expecting it, he was knocked off balance, and as Yasuko mumbled, "I got you!" he teetered and fell… headfirst, straight for the corner of the table.

'Crap,' was the only thought he could form before his head slammed into it, with a burst of pain.

Ryuuji gasped and bolted up in bed, feeling for his head. There was nothing… he'd just woken up, and the day was beckoning.

That had been an odd dream… weren't they supposed to be off-the-wall? It had been like he had already done his morning once, now, and as he checked his bangs, they looked just as fake as they had in his dream.

This time, he threw the magazine down with even more force, and the trashcan fell over just like in his dream. Strange. He stared down at the spilt trash for a second, before kneeling down—

That mold. It was in the corner again. Just like—

Had he had some sort of prophetic dream? Everything was turning out exactly like the dream, so far…

He prepared breakfast (pushing through the feeling that he'd already done it once) and moved to the messy main room to clean up. This time, he was more careful in his cleaning, picking up the clothes first and setting them aside before moving for the purse.

The legs grasping at his caught him by surprise, and in a moment of déjà vu he found himself falling, though he fell onto the rug this time. "I got you!" his mother mumbled.

"Mother!" he complained, untangling himself and standing up. "I told you last night I have school from today on, right?"

"How cold of you, Ryuuji," she pouted, but nodded in confirmation. "Congratulations on passing last year! Today's the opening ceremony, right?"

"Stop being so sarcastic," he said with a roll of his eyes.

She ignored him, instead ordering, "Hey, the room's dark. Open the curtains!"

"They are open," he said, repressing a sigh.

"Oh, the new apartment building," his mother remembered.

He mm'd in agreement. "It makes it hard to dry the laundry."

He shouldered on his jacket and grabbed his pack. "Anyway, I need to go."

He made for the door, but as he opened it and stepped onto the stairs, Yasuko asked, "You're leaving already? What about my meal?"

He grabbed the trash (he'd take it to the disposal site on his way to school), and called, "It's where it always is!" as he began to go down the stairs.

A thought hit him halfway down. Had he wrapped her meal? He'd prepared it, but… No, no, he hadn't wrapped it!

He spun on the steps, intending to head back upstairs and rectify the error, but a patch of mold (curse all fungus!) took the traction off one of his feet, and he slipped and fell backwards, trash spilling out around him as he slammed into the ground head-first—

He gasped and sat up, once again cradling his head. He looked around. He was back in his room. His uniform for the first day of the new school year hung on its hangar. But he'd already put that on today once—

No, not once. Twice. He'd dismissed it as a dream the first time, but—again?

"What on earth?" he mumbled, face still in his hands.
