Resisting the nausea, it took 10 minutes to apologize to the muscular maid clerk. Misaka Mikoto and Shirai Kuroko sat on the table opposite Yuu with dark faces.

"Yu, do you know what's going on?" Misaka Mikoto asked impatiently.

"Well, I know a little bit." Yu rubbed his head with a big head, he closed his eyes tightly, and was in a hurry to be poisoned by the crowd around him.

"Speaking of which, I actually turned into a big sister, hehehe~~" Shirai Kuroko untied his clothes with a smile, trying to put his eyes and palms into his clothes.

Bang-! !

Misaka Mikoto blew her red fist and glanced at Shirai Kuroko, who was covering her head and screaming. "Don't do bad things like my sister! Idiot Kuroko!!"

"Is it my sister-chan? I really regret Kuroko." Shirai Kuroko buried his face on the table and muttered in pain. "However, my elder sister actually has a younger sister? Could it be that... sisters are... flying..."

Bang! !

Another heavy punch hit the top of Shirai Kuroko's head, and Misaka Mikoto, who was wearing Shokuhou's face, gritted her teeth resentfully, and said angrily.

"Heizi, if you talk nonsense, you will die!!"

After solving Shirai Kuroko, Misaka Mikoto clapped her hands and said with a relaxed expression of venting her anger.

"Now we can communicate well."

"Well, I'll keep it short." You pursed her lower lip.

And at this moment, the crisp girl's voice suddenly sounded.

"World-class character replacement magic, the specific principle is temporarily unknown until I have seen the ceremony venue, but it is certain that this is an angel-level mystery. In terms of the effectiveness of the investigation, let's call it "Angel Falls" "Bar?"

The three people in the ice hall turned their heads, and what caught their eyes were a silver-haired girl in a nun's uniform standing outside the glass floor-to-ceiling windows, and a tall woman with a long knife and a ponytail.

Seeing the two people outside the window, Yun shrugged.

"It seems that I don't need to explain."

Chapter 171 Angel Falls!

Inside the "Colddew" store, Index and Kanzaki Kaori, who were standing outside the floor-to-ceiling windows, had come to Yu's seat.

Since this was a standard four-person seat, the petite Index could only squeeze between Yuu and Kanzaki Kaori, and the arrangement looked like a sandwich cookie.

However, compared to this, what made Misaka Mikoto more concerned was the weird scene of the three people in front of them that looked like a family of three.

She looked suspiciously at Yu's silver hair, then glanced at Index's pale silver hair, and then looked at Kanzaki Kaori's face, repeating this.

"biological?"

"Adopted."

Under the strange eyes of everyone, after the conversation between the two ended, they fell silent one after another.

Compared to Misaka Mikoto's silence, the perverted Discipline Commissioner with a strong sense of justice asked Index with a serious face.

"Can you describe the so-called angel fall just now?"

Obviously, the term that Index called before must be the main cause of the current strange phenomenon. As a member of discipline, Kuroko Shirai believes that it is necessary for him to stop such a vicious crime.

In other words, after finding the caster, can she just switch bodies with her elder sister? Well, this is a very tempting option.

"Stare—!" Index stared straight at the cake in front of Misaka Mikoto, her slightly parted lips and her green eyes revealing a strong desire.

"Okay, this is for you to eat." Seeing the hungry nun in front of her, Misaka Mikoto froze for a moment, then she pushed the cake to Index in front of Index, dumbfounded.

brush! In a flash, the cake originally placed on the dinner plate disappeared without a trace, leaving only a chewing nun who was holding her bulging cheeks happily.

"So fast!" X2

Misaka Mikoto and Shirai Kuroko said in unison with a look of astonishment.

"Since good-hearted people have given me something to eat, it is the nun's natural duty to explain the troubles of the lambs." Index folded her hands together, and said with a grateful expression.

"Obviously wanted it?" Hearing those shameless words, Kuroko Baijing muttered speechlessly.

Forcefully ignoring Kuroko Shirai's voice, Index pinched her throat and coughed dryly.

"The initial judgment of the principle of the technique is based on the concept of the "Tree of Life"."

"In the expression of the tree of life, the 'positions' of gods, angels, and humans are all fixed. Gods cannot become humans, nor can humans become gods, but the magic that is now being launched around the world has broken this theorem .An "angel" was pulled down from his position! "

"Huh?!!" X2

Misaka Mikoto and Shirai Kuroko blinked dumbly.

Ignoring the doubts of the two, Index continued to explain.

"Because the angel was dragged into the world and swapped his 'place' with a human, someone who lost his place was pushed into another place, like a domino, and everyone's place was swapped. .In the end, the person who casts this magic will be squeezed into the angel, taking the place of the angel who fell into the world."

After a pause, Index said with a rare serious expression.

"This is also the purpose of the person who uses this technique, to reach the heaven and become an angel!"

At the end of the sentence, Misaka Mikoto and Shirai Kuroko's eyes started to turn in circles.

... This is an angel falling into the world, a position, a magic technique, becoming an angel or something, if it wasn't for that old grandfather in an elementary school uniform outside who was crossing the road, who would have believed it! !

"In other words, someone wanted to be an angel, so he activated this technique of swapping people's appearances?" Misaka Mikoto stroked her forehead, rubbed her forehead, and moved her body with a stern look on her face. said.

"That's the way it is, but are you uncomfortable? You've been twisting around like this all the time?" Index tilted her head and looked at Misaka Mikoto with some doubts.

"I don't know how, but my whole body is sticky." Misaka Mikoto's face froze slightly, and her cheeks were blushing as she muttered. She always felt that somewhere under her body seemed to be particularly sticky, as if something was flowing out.

"Cough cough!!" You coughed twice, and looked away erratically.

"What, I just said how did my body become like you, it turns out that we exchanged, Misaka-san~"

A voice full of sweetness came from behind Misaka Mikoto, she was stunned for a moment, and turned her head quickly, but what she saw was a young girl with the appearance of Junko Hoikaze, with shining star eyes.

"Shokuhou?" Misaka Mikoto said uncertainly. She remembered that in the ice hall, it seemed that Senior Sister Koukoko in the faction was next door.

"Anthracene, it's me. Really, it doesn't matter if Fanfeng becomes a mouthful. I actually exchanged with you, and I was planning to take a shower just now."

Shokuhou, who was remotely controlling the early bird, looked like I was in trouble, and sat beside Kuroko Shirai with a bad look on his face.

"Ah!! Sure enough, this sticky feeling is your fault!!" Misaka Mikoto covered her skirt and looked at Shokuhoumao with an angry expression.

"Slimy?" Shokuhou Cao was stunned for a moment, and then he reacted, throwing off the skirt of Misaka Mikoto, who was wearing her own appearance, and a trace of panic flashed in his eyes. "What are you talking about, I don't understand at all!"

"Speaking of which, there is indeed a strange fishy smell." Shirai Kuroko rubbed his chin, shrugged his nose, and frowned.
