It had been a week since Yukiteru Amano had killed Takao Hiyama by destroying his Diary with a dart. The same day he learned he was in a Survival Game, with the goal being to murder the other participants and become God. The same day he learned he had a creepy (but admittedly attractive) stalker named Yuno Gasai. Yuno was dangerous, but she was useful. That day was insane.

But today? Today was like some kind of nightmare. An hour ago, someone had walked out of a glowing blue portal, killed the substitute teacher, and locked the classroom door with the students still inside. Who was this boy? What did he want?

And why did he look exactly like Yuki?

The boy walked around the classroom slowly. He tilted his head to one side and stared at Hinata Hino.

"Hinata," he said, with no emotion in his voice. He offered no explanation as to why, leading Yuno to believe he was saying it just to prove he knew who she was. Her suspicions were all but confirmed a few seconds later, when he walked over to Mao Nonosaka's desk.

"Mao."

He walked over to Ouja Kosaka's desk.

"Ouja."

He walked over to Aru Akise's desk, and stroked his hair gently.

"Aru~"

He walked over to Moe Wakaba's desk.

"...Moe," he said, rolling his eyes.

"He walked over to Yuno's desk. He didn't say anything for about two minutes. He just stared into her eyes. He knew these eyes. He had loved these eyes. He had been betrayed by these eyes.

"WHORE!"

He grabbed Yuno's hair and slammed her face into her desk, giving her a bloody nose. He hated these eyes. He slowly walked over to Yuki's desk. Yuki was absolutely terrified. He leaned in towards him.

"Yukiiiii~" he said, sounding exactly like Yuno.

"What...what the fuck are you?"

The boy smiled. "A fair question. I am you. That is a fair answer, and you should be satisfied with it. Yuno would believe that to be a very fair answer." He rotated his head sideways towards Yuno. Yuki cringed as he heard a sickening "crack". "Wouldn't you, my love?"

Yuno's eyes widened in horror as she realized who the boy was. "Y...Yuki?"

"The one and..." The boy stopped talking. He also stopped moving and breathing for a few minutes. Yuki got up, planning to somehow escape by crawling out the window. As he walked past the boy, his hand grabbed Yuki's throat and threw him to the ground.

"ONLY!" the boy shouted in rage.

"Y-Yuno! Help me!"

Yuno just stared in complete terror. "I...I can't."

"That's right, Yukiiii, she can't. And do you know why she can't?" The boy licked the side of Yuki's face. His tongue moved slowly, but not as if he was intentionally slow. It appeared more that this was simply his tongue's maximum speed.

"BeCAUSE, she CAN't deCIDE BETWEen the BOY SHE LOVES AND A STUPID, STUPID COWARD!" he screamed, emphasizing random syllables. "It's funny, isn't it? She has loved us both, and yet we do not love her. I despise her, and you feel a mixture of fear and apathy."

The boy jumped a few feet towards Yuno's desk, still choking Yuki. "YOU SURE KNOW HOW TO PICK 'EM, BITCH!" The boy calmly let Yuki go and walked towards the teacher's desk. "I'm gonna tell you a story, boys and girls." The boy forced an unnatural smile. "It's about Romeo and Juliet. Oh, Yuno, you'll love this."

"Yuki, please..."

"You had your time to ask for forgiveness, Second. Funny, isn't it? How so many stories start with two, but end with one? You killed your parents, and you were all alone. You have Yukkiiii, but you'll lose him too, I know you will. We had each other...and I was all alone. But now I'm two again. I'm two and one. I am you, and you are me, and we are all together. Two always ends with one. I'm living proof. Well...no, not 'living'. That's not the right word to use."

The boy paused for a few seconds until shouting:

"NOW! ON TO THE STORY! You see, Romeo and Juliet were very young, and they loved each other very much. But sadly, they decided to kill themselves. Oh, how tragic! It brings a tear to my eyes. However, Juliet was a LYING, ROTTEN WHORE AND FAKED HER DEATH!"

He paused. "I think. Truth be told, I don't think that's how it went at all...but who cares? The point is...something that I forgot. But I wanna ask you something, Yuno."

He walked up to her. "Did you even spend a few minutes crying after you murdered me? Or did you just hop over to the next timeline the second after the poison did its job?" He laughed silently. It was extremely unsettling. "Get it? Second?"

He glared at Moe across the room. "That was a joKE. LAUgh."

Moe laughed nervously. "STOP LAUGHING AT ME!" he shouted, throwing Yuno's desk at Moe's feet. She stopped.

He walked back over to the teacher's desk, and paused. He started whispering to himself silently. The whispering became louder and faster, until finally he said something loud enough for everyone to hear:

"A lobotomy."

He turned towards Yuno. "Yes. A lobotomy. That should work."

The boy's right index finger elongated. Yuno could see new bones forming under the finger's skin. He slowly walked towards her. He paused, ran towards the door, opened it, told Minene Uryu to come back later, and slammed it. He then slowly walked towards her again.

"You know, Yuno. You know why I'm doing this." He smiled and revealed his teeth, which were elongated, thin, serrated, and razor-sharp. "It's because you're craaaaazzyyy, Yuno. Stupid, crazy Yuno. Starving for stability. Locked in a cage of her own madness." He suddenly grabbed her shoulders. Yuno noticed the stitches appearing around his face and neck.

"YOU'RE SO FUCKING CRAZY, YOU WON'T EVEN REMEMBER THIS NIGHTMARE!"

Yuno woke up screaming. Yuki jumped out of bed, landing on his face. He quickly got back up.

"Who's there?! I have a horse vibrator and I'm not afraid to use it!"

"It's okay, Yuki. I just had a bad dream."

"Again? That's the fifth time this week."

"I know. I'm sorry for waking you up again."

"It's okay, baby. Do you remember anything about this one?"

"Just bits and pieces. I don't get it. Doesn't it usually take a few more minutes for people to forget their dreams?"

"Yeah...look, Yuno. I need to ask you something, and I need to be honest with me: are you alright? The same dream five nights in a row, and not even being able to remember most of it...that's not normal." Yuki paused. "Are you taking your meds?"

"Yes, I'm taking them!"

"Alright, just...just calm down. I'm sorry, baby, I didn't mean to upset you." He hugged her tightly. "Yuno, answer my question. Are you alright?"

Yuno started to cry. "No. No, I'm not alright. I'm stressed out over nothing, I'm scared out of my mind, and my head's spinning. I...I think I'm losing my mind."
