3rd POV

-Flashback-

"You promise?"

"Yes, let's get married when we grow up, Hagakure-san." A small girl said.

"I have the locket." He started.

"And I have the key." She finished.

"That would be nice, to see you all grown up," Hagakure said.

"Mmhm!" The small female grinned.

They both laughed and played around on the hills, waiting for the sky to darken and for their parents to separate them.

Now the real question is: Who is the Promised Girl?

-McFlashback-

Y/N's POV

Hagakure came from a good family. They loved him.

I, however, had an entirely different story.

"Oh, Y/N, your ribbon's loose." Hagakure pointed out. He reached his tiny fingers around my ear and pulled the ribbon tighter. "There we go!" He smiled brightly, and I did the same.

"Thank you, Hagakure-san!" I screamed happily, tackling him in a hug.

My three other friends, Celestia Ludenberg, Aoi Asahina, and Sayaka Maizono, ran up to us.

"Y/N! LET'S PLAY HOPSCOTCH!" Aoi screamed happily, a silver key tied to a string dangling around her neck.

"Hm? Oh, can I play?" Celestia asked, twirling a copper key around her finger.

"Sure! Let's all play together!" Sayaka smiled, a gold key poking out of her pocket.

"YEAH!" Hagakure shouted, reaching for the blue chalk.

I held up my key: bronze. It wasn't as intricate as Aoi's, Celestia's, or Sayaka's, but... just maybe it could do the trick.

-Present-

I grabbed my pencil and jotted down some notes in my notebook. 

'It seems that I have fumbled into a classroom. Maybe I had been knocked out with a gas or sleeping powder of some sort. I shall investigate it immediately.'

My feet immediately started to move, walking down the halls, clutching my investigative journal in my hand.

A migraine was pounding against my head, making my skull hurt. I was used to it though: staying up long hours of the night, writing notes and theories in my journal.

I remember why I started this whole "hobby" anyways.

It had been a dark place where I grew up. The slums weren't inhabiting the kindest people. 

One day, in the front of my very own house, I saw my own mother getting murdered by a man in a ski mask.

Typical, isn't it?

Well, I obviously dropped to the ground and held her hand, for my father had died two years earlier in a car wreck with an angry aristocrat. Of course, they got away because they were rich.

This murder had happened after I got my key from the book that my friend always read. The words still are printed in my mind today.

"Zwase is love."

I... hate to admit it... but I can't remember his name or face. It's just all... a blur.

"Hm..." I hummed to myself. "I wonder where you are..?" I clutched the bronze key looped around my neck in a necklace tightly.

Anyways, after my mother's murder, a man had travelled to my "hometown" and investigated me, asking me questions about the man's appearance.

"Um... he had long black hair... and red eyes..." I remembered saying. "He was this tall." I had raised my hand up a bit, symbolizing the man's height.

All while I showed the journalist the man's description, he smile down at me and patted my H/C hair.

"What's your name, little girl?" He asked.

"U-Uh... I-It's Y/N... Y/N L/N." I said shyly, trying not to remember my mother's corpse laying in front of me.

"Oh, that's a pretty name, Y/N! My name is Ouma Kokichi, a professional journalist! I'm sixteen years old. How old are you?"

I rubbed my hand against my arm. "I'm turning six today. It's my birthday..."

His eyes grew wide before filling with sympathy. "I'm sorry, kid. Anything you want from me?"

Confused because I didn't know why he was offering me something, I stared at his journal. "Can I help?" I pointed towards the bound sheets of paper.

"Oh, with the investigation?" He questioned cautiously. "I don't know. I can't just pick up a kid and tell her to help me investigate..."

"Please..?" I asked, practically begging with puppy-dog eyes.

He sighed. "Fine. Follow me."

Happily following "Ouma", I tried my best to forget about my mother's death and move on.

I remember those days. Ouma had died while protecting me a few years later during the investigation. At that time, I was eleven, and I still had my key but never saw my friends again. They were already just a distant blur.

I picked up the case, a solved who the murderer was: Izuru Kamukura.

Long story short, he got arrested (though he was quite clever about dodging the police). I still remember Ouma. He... was like a big brother image for me. Over the years, I had picked up journalism, and eventually, it would become my strong-point, my forte.

Back to the present, I started limping down the halls, clutching my head in pain. Out of all people, why did it have to be me?

I grabbed my pencil and quickly wrote down a phrase. 

'I think I'm all alone.'

A light ahead grabbed my attention, and I started to walk towards it. Double doors lead into the gymnasium, and I quickly pushed it open, sucking in my breath.

In front of me stood sixteen other people... They were... confused like me as well...

"Eh? It's a person!" A man with wild hair and holding a crystal ball exclaimed, nearly dropping his object.

"You are fifty-three seconds late! You were instructed to arrive here by eight o'clock SHARP!" Another man with red eyes and wild eyebrows cried out, steam almost blowing out of his ears.

"Sorry, dude..." I mumbled, starting to walk towards the closest girl I saw.

She turned around, and greeted me with a smile. "Oh, hello! My name is Saya--"

Her speech was cut short when she saw my face. 

"Huh? Cat got your tongue?" I asked. "I'm Y/N L/N, Ultimate Journalist."

She paused for a moment before muttering under her breath. "You look awfully familiar."

"What's that?"

"Nothing." The girl started to breathe in and out before finishing our introduction. "My name's Sayaka Maizono, Ultimate Pop Sensation."

In the corner of my eye, I saw her wearing something around her neck: a golden key sculpted in the shape of a heart.

The more I looked around the room, I noticed that another girl with black and curly hair tied in pigtails had a copper key chained to her waist as an accessory.

Then, another girl, most likely the last, was talking to another girl...? Anyways, she had a silver key poking out of a red jacket.

Why... Why does this seem so familiar..?

[Three Weeks Later]

"Hagakure-san! Come here!" I shouted, trying to juggle all the books and other "magical" items at once.

I heard his wooden sandals clack down the halls in a hurry, hoping that I didn't find a mangled corpse. 

"What's wrong Y/N-icci?" He asked, his face slightly panicked.

"Can you p-please help me with these..?" I asked, feeling myself ready to collapse under the weight of books.

"A-A-Ah! Right!" He stuttered, picking up some of the books and objects that I was holding in an awkward position.

"Thank you..."

He laughed a bit, a blush visible on his face. "No problem, Y/N-icci!" 

For a moment, I swear that I could see a pendant sticking out of his pockets. Maybe it was my imagination...

"What's that?" I asked, pointing towards the golden item peeking through the cloth.

He seemed confused for a while before pulling the pendant out. If he was blushing before, it was 100 times worse this time.

"I-It's... a promise I made with a girl when I was younger..." He said, smiling at the memory. "I told her that we'd marry when we grew up, and she would be able to unlock it with her key..."

My mind clicked.

I had a key... Was... was he the boy I fell in love with when we were younger..? No, I don't remember promising him anything... and how can I be sure that it's actually him..?

"Hmm? Y/N-icci, is there something wrong?" He asked, looking at my pale face.

I snapped my head up from my thoughts. "Ahah... it's nothing... Sorry to bother you, Hagakure-san..."

For a moment, I saw his eyes flick down to my necklace before smiling once again. "It's fine! Kirigicci might be calling me so--"

"BING BOM POM POM! A BODY HAS BEEN DISCOVERED!" The loudspeaker crackled. "After some time has passed by, a classroom trial shall begin..! Upupupupu~"

"Hagakure-san! Let's hurry and find the others!" I said, a cold sweat now starting to form on my face.

"C'mon! Let's go!"

***

Y/N's POV

"S-Sayaka-san...?" I mumbled, tears threatening to spill. 

A single knife was stuck into her stomach, and pink blood oozed from her deathly pale body. My eyes traced the horrible sight until I caught hold of the golden key around her neck.

When no one was looking, I gently lifted the key from her neck and stuffed it into my hoodie's pocket. Then, I smiled bitterly at the corpse before putting my hand on her head. 

"Miss you, Sayaka-san..."

-After the Class Trial-

I was... mortified to say the least...

Leon's execution... was just brutal...

Having your own talent--something that you love and hope to fulfill when you're older-- turn against you and cause your Ultimate Death...

It was a sad fate, indeed.

Yet, I won't let that damper my spirits! I still have two keys for solving a hidden mystery. 

Who was the guy that held the locket? Sure, Yasuhiro has a locket, but can it really be the same one that was given to us oh-so-many years ago?

"Excuse me, but I couldn't help but notice the key you're holding in your left hand." A calm and collected voice cut through my train of thoughts.

As my body spun around, my H/C eyes caught with a red pair staring back at me. "Huh? You're Ludenberg-san, right?"

"Yes, that is correct. Y/N L/N, wasn't it?"

I nodded.

"Please come to the cafeteria at precisely one o'clock. Three people, including myself, will be there. Don't be late."

Just like that, she walked away.

I held up Sayaka's golden key and my bronze key.

'I wonder if this is the main reason why Ludenberg-san approached me...'

***

[12:58 in the Cafeteria/Dining Room]

Y/N's POV

"I-I'm here!" I ran through the doors, clearly out of breath from running.

Just before, I had went into my room and locked the door so that I could fall asleep after the fiasco unfolded today.

Celestia looked up from her tea and lowered the cup, revealing a smile. "Aoi, Yasuhiro, are you there?"

The two poked their heads out of the kitchen, laughing to themselves. 

"B-But the peach..!" Hagakure laughed.

"IT'S HUGE!" Aoi finished, both of them bursting into fits of laughter.

I was confused before Celestia explained in a few simple words. "It's a dirty joke."

"Oh..." I rubbed my arm, self-conscious about the events about to come into light. Plus, I saw that Aoi and Yasuhiro are having a blast: joking around, whispering to each other, blushing.

In the pit of my stomach, I felt rage, jealously...

Before I could put my thoughts into words and words into actions, I heard Celestia walk over to Hagakure and pull the locket out of his pocket.

"Hey! I'm gonna marry someone with that one da--"

"Shush." She said promptly, putting the locket on the table. "We all have the key... except Sayaka... Y/N got her key in time, though."

"Eh?" Hagakure asked, confused. "What's going on Asa-icci?"

"We're... finding out who the Promised Girl is..." Aoi said, blushing a bit. "We need to know who made a promise to marry you. I mean, you're like a brother to me, but I wouldn't mind, really...." 

"I'd rather not marry him." Celestia said flatly. "I already have marriage plans."

For a second, I couldn't sworn I saw Hagakure turn over and look at me, hope filling his eyes.

"First, I'll use my key." Celestia twirled her copper key around her finger with the metal accessory. She carefully inserted the key and turned the lock, but it didn't work. "Phew!"

"Hey!" Yasuhiro yelled, slightly offended by Celestia's little remark at the end.

"Now, for Sayaka's key." 

I placed the golden key in the raven's hands, and she put the key in the lock, but it didn't budge either.

"My turn!" Aoi smiled cheerfully. 

Crossing my fingers, I watched intently as she slid her silver key into Hagakure's locket before shaking it around and twisting it. 

"Pooey... it didn't work. Oh well!" Aoi said with an ever-lasting smile on her tanned face.

"I guess it's my key next..?" I asked, approaching the lock.

Before I could reach it, however, I felt a pair of hands behind me grab my waist and pull me back.

"Can I do the honors..?"

I gulped from our close proximity, but I managed to hand him my key. He quickly rushed over to the table and put the key into the keyhole, slowly twisting it.

A satisfying 'click' was heard, and the locket opened.

A piece of paper fell down on the ground, and Yasuhiro bent over to pick it up. When he flipped it over, his eyes widened.

"Woah..." He mumbled.

"Is that a young Y/N..? She looks so... dirty..?" Aoi said confusedly. "Didn't you grow up in a nice neighborhood?"

"Funny story, actually..." I smiled nervously, rubbing my arms again.

"Look, they're holding hands." Celestia pointed.

Hagakure set down the photo and turned over to me. A smile was engrained on his face with stubbles.

"Y/N... I want to keep the promise... I've been in love with you ever since you walked into that gymnasium. What makes it even better is that we have history. Can we please keep this promise?" He asked.

"Aww!" Aoi cooed.

"It'd be lovely to keep that promise. After all, my love for you is crazier than your hair!" I chuckled.

He rolled his eyes and grabbed me by the waist, pulling me in. Our faces were really close, especially our lips.

"We'll just leave...." Celestia said, pushing a fangirling Aoi out of the kitchen. "Use protection."

Hagakure chuckled at that comment, but I just grew redder and redder.

"Yasu-san... this... this is my first kiss..." I mumbled quietly, avoiding his eye-contact.

"Mine, too. There's a first time for everything." He said softly. "Close your eyes."

I did as he said, and my eyes fluttered shut. Before I knew it, I felt his soft lips on mine, moving in sync. It was as if our lips were made for each other...

All I remember was that I needed to survive to start a family with the one man I fell in love with since childhood. 

'I love you, Hagakure...'
