Chapter One

Midorima stepped onto the slick floor of the Teikou Middle School basketball court. The first day of training camp had been long and intense, but the sharpshooter found no cause for complaint as long as he could further perfect his basketball.

The only person who had beaten him to the court was his team Captain, Akashi, who was in the middle of some stretches

"You're early as usual nanodayo, Akashi," remarked Midorima, dropping his bag at a corner.

Kuroko looked up. He could see Kise standing before him, but Akashi was nowhere in sight. Kuroko could have sworn he'd just heard Kise say, "nanodayo", but thought he must have misheard him.

"Good morning, Kise-kun," said Kuroko as he peered over Midorima's shoulder, trying to see if Akashi was there.

Midorima, thinking that Kuroko was addressing Kise, also looked behind him. When he saw no one, he flipped back around.

"Hm? Where is he?"

Kuroko thought he was referring to Akashi.

"No idea," he said, slightly puzzled. "Kise-kun, since when did you stop addressing Akashi-kun as Akashi-cchi?"

Midorima whirled around, but there was still no one behind him. He stared blankly at Kuroko. "Huh? Were you talking to Kise?"

Now Kuroko was staring back. "What do you mean?"

Completely nonplussed, Midorima asked, "Akashi, who have you been talking to all this time?"

Kuroko was genuinely concerned now. He peered closely at Midorima's face.

"Kise-kun, I'm Kuroko, not Akashi-kun. Are you feeling well?"

Midorima stood stock still. Kuroko scooted closer to him, still looking concerned.

"Have you been drinking sake this early in the morning?"

Midorima became affronted. "Akashi, is this some kind of a joke?"

"I am not Akashi-kun; I'm Kuroko," said Kuroko patiently. "I would try to detect traces of alcohol from your breath, but since you just woke up…"

"Now you're just being rude nanodayo," said Midorima irritably. Convinced that Akashi was messing with him, he made his way over to where the basketball cart was parked.

Kuroko paused. He hadn't imagined it – Kise had just used Midorima's catchphrase. He observed Kise carefully. His friend's speech and movements seemed steady, so he couldn't be that drunk. Or was it all just a huge joke on his part?

"I'm not trying to be rude, Kise-kun," said Kuroko sincerely. "I'm just worried about you."

Midorima retrieved a ball from the cart. In one smooth motion, it soared from his hands and dropped through the net with a soft whoosh.

"You're the one you should be worried about nanodayo," said Midorima, returning to his bag. He fished out something from inside it – a round hand mirror.

"What are you doing, Kise-kun?"

"Proving to you that you are a susceptible victim of morning grogginess nanodayo," said Midorima matter-of-factly. "Come and have a look."

"Green… like Midorima-kun's hair. I didn't know you carried such a thing around, Kise-kun."

"It's my lucky item nanodayo. And how many times do I have to say, I'm not Ki – "

They both froze, mouths agape.

For some horrible, twisted reason, their reflections had morphed into the faces of Akashi and Kise.

Before either of the boys could begin to make sense of the situation, the door of the court slid open.

"What's up, guys? You look spooked! I understand if it's Kise, but it's not like you to be ruffled, Akashi."

It was Murasakibara, striding casually up to them with a great big grin. They stared mutely at him. Then it struck Kuroko that Murasakibara had just addressed Kise normally, without the usual 'chin' affixed. Once more, he looked at the faces reflected in the mirror.

As though a light bulb had switched on in his head, the Phantom Miracle realised what must have happened.

"Murasakibara-kun," he said, looking up uncertainly, "that's not you, is it?"

The grin slid off Murasakibara's face. He looked behind him, but there was no one there.

"The hell are you saying, Akashi? And why are you speaking to Murasakibara when he's not here?"

Kuroko and Midorima recognised the familiar symptoms with full-body dread.

"This isn't possible," muttered Midorima edgily. Kuroko, on the other hand, was gazing at Murasakibara with growing comprehension; the frown on the guy's face was unmistakeable.

"Aomine-kun, is that you?" asked Kuroko.

"Ah?" Murasakibara was full-out scowling now – and it was a scowl highly reminiscent of the Teikou ace player. "What sort of question is that?"

Midorima seemed to have recognised him, too.

"It's Aomine for sure nanodayo."

"The hell? Kise, why are you adopting Midorima's style of speech?"

"Aomine-kun," said Kuroko resignedly, "I think the three of us have switched bodies."

He gave Aomine the mirror. Aomine's mouth fell comically open.

"How – how is this even possible?" he demanded, goggling at Murasakibara's equally scandalised reflection.

It took some time for the three of them to regain their bearings.

"So Tetsu is in Akashi's body," said Aomine in disbelief, "and Midorima is in Kise's body?"

"That's right." Midorima sighed and pushed up his glasses before remembering that they weren't there. He wondered why he hadn't noticed this until now; probably he had gotten too used to them.

Aomine checked out the ground below his feet. "I did wonder why I was feeling a little taller than usual," he muttered, scratching his head. "Damn..."

"Any normal person would have noticed such a drastic difference in their height nanodayo," pointed out Midorima shortly.

"And any normal megane would have noticed if they weren't wearing glasses, you Oha-Asa fanatic."

"Please stop fighting, you two," said Kuroko. "We have to look for the others. It might be possible that they've switched bodies, too."

Aomine suddenly snorted with laughter.

"Can you imagine Satsuki in Akashi's body? She'd throw a queen-sized tantrum!"

"There is nothing funny about this, Aomine," said Midorima sharply. "Kuroko is right. We must find the others at once nanodayo."

"Oh, you guys are up early!" piped up a cheerful voice.

It was Momoi. Their manager was all smiles as she skipped happily toward them, though she seemed surprised to see Aomine.

"My, it's rare to see you awake at this time, Mukkun," she remarked curiously.

"I'm not Murasakibara," said Aomine bluntly.

"It seems that Momoi has not changed nanodayo," observed Midorima.

"Eh? Ki-chan, why are you imitating Midorin?"

"I am not Kise nanodayo."

"Eh? What do you mean? Akashi-kun, what's going on?"

"It's a little hard to explain, Momoi-san," said Kuroko uncomfortably. "First of all, where are Kise-kun, Murasakibara-kun and Akashi-kun?"

"Eh? What on earth are you talking about? You're standing in front of me, aren't you?"

"He meant 'where are Tetsu, Aomine and Midorima?'" rectified Aomine.

"Oh – they're still asleep," said Momoi, blinking rapidly. "Hold on, guys. You're talking and acting somewhat different today – "

"We'll explain later," said Aomine, making for the team's sleeping quarters. "Come on, slowpokes!"

They entered the bunk to find the other team members still tangled in their sleeping bags.

"Let's see," said Aomine, a mischievous grin spreading across his face all of a sudden. "Before we wake them, let's take a guess who's who, shall we?"

Midorima made the act of pushing up his glasses again.

"The uncouth man inhabiting my body and snoring with his mouth so rudely open has to be Murasakibara nanodayo," he said, tone marked by disapproval.

Aomine had difficulty hiding his guffaws; seeing Midorima snoring so unglamorously was more than he could take.

"So that leaves Kise-kun and Akashi-kun," said Kuroko, his eyes roving from one to the other. It was strange to be watching his own body dozing on the futon. Whoever was in it was lying on his side, legs tucked up a little. It reminded him of a kid.

Could it be… ?

"Is something wrong, Kuroko?" asked Midorima, noticing his friend's preoccupied expression.

Kuroko shook his head.

"No, it's nothing. I just didn't know I looked like that in sleep."

"Not at all. You usually have your fingers neatly intertwined on your stomach nanodayo."

"I see. Midorima-kun also has a good sleeping posture."

"I'll take that as a compliment."

"As for Aomine-kun, he sleeps pretty much the same way he plays basketball," added Kuroko, now watching the person in Aomine's body, who had an arm over his eyes. "Some nights he'll be facedown, others he'll be flat on his back with his arms spread open in a V-shape, and still others he'll be – "

"Oi, enough about me already," snapped Aomine annoyedly.

Momoi was watching the proceedings with wide eyes. Clearly, she hadn't the faintest idea what was going on. Meanwhile, Aomine had given up on the guessing game.

"It seems we won't know for sure until they voice it out themselves," he said, prodding his own body. "Oi, you, the one possessing my precious body! It's time to wake."

"Aomine-kun, I wouldn't do that if I were you," said Kuroko hastily – if he had guessed correctly about who was in whose body, then…

The Aomine lying on the futon dropped his arm. They saw his eyelids flutter, and then part slowly.

"Atsushi," said the fake Aomine in a dangerously soft tone, fixing his narrowed eyes on Aomine, "what is the meaning of this?"

Uh oh. Aomine swallowed, backing up warily. "A – Akashi…?"

"You've got some nerve, waking me in such an indecent manner." The fake Aomine's piercing eyes, which could strike fear in people's hearts, were now alight with a terrifying menace.

"It's not that like, Akashi," Aomine tried to explain, as Akashi got to his feet, still glaring at Aomine with something bordering on murder. "I was trying to – "

"There is no excuse that will condone you, Atsushi," interrupted Akashi, "And since when have you addressed me as Akashi?"

"Akashi-kun," said Kuroko, stepping forward to save Aomine.

At the sight of his own body speaking to him, Akashi's expression transformed in a flash.

"What the - ?" he exclaimed, gaping at Kuroko in shock.

"Oh? Is everyone up already?"

Kise was sitting up, yawning widely. Beside him, Murasakibara stretched like a languorous cat.

"Hm? Midorima-cchi, did you change your sleeping spot?" questioned Kise, upon catching sight of Murasakibara.

When Murasakibara didn't heed him, Kise's lips formed a grin.

"Aw, you could have just asked, Midorima-cchi. There was no need to be embarrassed."

"Dream on, moron," said the real Midorima irritably.

"My God!" gasped Kise, having just spotted Midorima standing over him in his own body.

"Let me explain, everyone," said Midorima, stepping forward authoritatively, "it would seem that the six of us have swapped bodies nanodayo."
