"Tsukasa!"

"Oh!? (Y/N)!"

"Tsukasa, we were going to take off my Yorishiro... Do you want to come with me?"

...

It's been a couple of weeks since the fake world incident.

Amane, Mitsuba and I acted as if it never had happened, which is for the best. I didn't meet Amane or Tsukasa more than before either.

And of course, along with many other School Mysteries, Amane asked me for my Yorishiro.

-------------------------------------------

"Yashiro, Amane, and Tsukasa... Welcome to my boundary." I play the lullaby on the piano. "Let's do this quick and get it over with."

Just as I finish, I hear an odd sound. "Wait a minute..."

"Hanako-kun? Tsukasa-kun?" Yashiro gasps out as she sees the two boys shed a few tears. In Yashiro's eyes, it's a weird sight for sure.

"Alright! My boundary is open for business!" I hop up from my piano stool and pat my brother's heads with a grin. "You two were such crybabies since the day we were born. No wonder I was the best child!"

The two embarrassingly wipe their faces and start following me.

We start walking into my boundary, the music storage room.

...

"SAKURA-CHAN?"

"Oi, Tsukasa. Indoor voices. My boundary, my rules." I then look at Sakura, "Thanks for waiting!"

"How is Sakura here when the only way to get in is to play the tune?" Yashiro asks, being the only sane person in the room besides Sakura.

"I taught her! She helps me after all, and she's surprisingly good at the piano!"

"Oh... EH?" Tsukasa observes his assistant.

"I know it's unbelievable, Tsukasa.... but deal with it. Come on, we should get done with what we need to do."

"Jisatsu-san is correct... And Tsukasa, please get off me.

"Let's see what you have!" Yashiro exclaims.

"Chill, let me take out my keys." I say while taking out the yin yang and piano keychains, still attached to the key. Tsukasa and Amane quietly stare at the keychains.

"But... there's no lock...?"

"Yashiro, right now, patience is the key." I hold out my small piano keychain and press the small button attached to the bottom.

"Woah!"

"It's so cool, right?!" Once I press the button, the light gets dimmer and the room shows a bright yellow key hole on the ceiling.

"It took me a long time to get all this ready, so if you don't like this, you're dead to me."

I take the ribbons out of my hair and pull myself towards the ceiling. Eventually, I open the door and take out a small, wooden music box with a silver crescent on it.

As I float back to the floor, I observe the box. It seems to be getting old now. The colour is slowly fading, and there are scratches and dents all over it.

"Yashiro, catch!" Yashiro barely manages to catch the music box I toss at her, after I pressed the button again to go back to its normal state.

"Amane, Tsukasa, You two can open the compartment. Here are the keys." I tossed them the yin yang keychain and they gave me a look.

They realise everything I used was a gift from them on our birthday. The music box, the keychains, and even the ribbons, were my last birthday presents.

Opening the compartment, they find a photo with a seal on.

The photo was taken when we were 10 years old, on the day of my last piano performance. It was a photo of me wearing a blue dress and the boys wearing formal clothing hugging each other with a bouquet on my arm. We were all smiling together.

"Here, Yashiro... take the Yorishiro off."

"Jisatsu-san... Are you sure?"

"Yup, I'm sure!" I smile at her. "And by the way, you can call me (Y/N) now!"

"Okay..." She doubtfully looks at me and then puts on a determined expression. "3... 2... 1...!"

I get out of my position and swing over to catch Yashiro. I walk over to hand her over to Amane but then suddenly drop her as I realise something.

"Damn it, Amane, Tsukasa! I just remembered! I need your help... she's going to start crying and screaming when she's out of that phase."

Amane quickly goes to catch Yashiro Nene as he looks up at me.

"Huh?" Both my brothers question.

"She's going through a part of my memory... and it's the worst one of all."

"What's the worst memory you have, (Y/N)...?" They both doubtfully look at me, worried.

I quiet down my voice. "Well, Tsukasa, in case you didn't know... I guess it was the day Fate decided to hate you both."

Where... Where am I? Some kind of parking-lot?

Oh!

I look around to see (Y/N) holding grocery bags. I should follow her.

It's a cloudy day. The sky is grey and it seems to be almost dark. Trying to find a clock, I turn from direction to direction but to end up failing.

Why is she alone outside at this hour?

"Woah, today was a jackpot! Can't believe I got a one for three deal!" (Y/N) holds up the bags, stretching to the sky. "I hope the boys aren't too hungry."

What she says and her physical appearance does not add up.

Is she helping her mom to go to the market instead of her? Without any words, she keeps following her.

...

After walking for a while, (Y/N) goes inside an old building. It seems like a really old apartment flat.

This building looks like it's about to fall down... The walls are tearing down and there's waste everywhere...

...Doesn't she live with Hanako-kun and Tsukasa-kun?

Is... Is this her home?

How can a house this small support such a large family...?

Approaching a door, she swings it wide open and drops the grocery bags on the floor. It's a rather small house.

"Guys, I'm home! Who's hungry? You won't believe it, I got a really good deal today!"

No answer.

"Amane? Tsukasa?"

She looks like a mom trying to find her children, but her childish voice destroys the image.

This house... Isn't in the condition for someone to live in...

I quietly observe my surroundings. This house is just like those haunted, abandoned homes in horror films.

Oh, (Y/N) is turning the corner. I should catch up.

As I walk over, the first thing I notice is (Y/N) on the ground.

Her brown eyes are as wide as saucers, she covers her mouth to keep down a sob.

"(Y/N)...?" I quietly whisper, even though I know she won't hear me.

I'm too afraid to look up. What's going on...?

But at the same time... Deep down... I know what it is...

Wait... That's...

The picture that I was holding a few minutes ago stands in front of (Y/N), covered in red.

Isn't that... Isn't that-...!?

My eyes trace up the blood in the room.

Hanako-kun and Tsukasa-kun are on the ground with blood all over the kitchen.

There are knife stabs on Tsukasa-kun's body and a knife handle jutting out of Hanako-kun's body...

My stomach's sinking in my body further and further. I feel like I'm about to vomit...

Hanako-kun... Hanako-kun...

"HANAKO-KUN!"

I feel a rush of relief being back in the boundary, as if I had carried the weight of the sky just before.

"Y-Yashiro!" My legs don't want to hold me up and my vision is blurry.

"H... Hanako-kun..." He hugs me tight and strokes my head.

"It's okay, Yashiro. I'm here, don't worry."

The girl who was crying only a few seconds ago walks in front of me with a frown. "I guess you saw the worst part, huh."

(Y/N)...

"(Y/N)... What happened?"
