Ghoul is a monster which disguises like a normal human being, they talk, laugh, and maybe be a popular or super smart people. But, on the darkest night, these monsters hunt down the dead flesh of humans.

When I was a child, I always think Ghoul was just some bad characters in a story.

They didn't exist, and even if they were real what people called Ghoul Investigator would kill all of them and saved the day just like heroes on a story.

I guess I interpret the story in a wrong way.

"Yuu-chan… Stop reading newspapers and solve this problem, I promise this is the last one."

"…."

"Yuu-chan, Do you even understand what those kanji means?"

"… Shut up."

"Hey, Yuu-chan."

"…"

"Yuu-chan!" Said the blond boy after he snatched away the newspaper on Yuu's hand, and when the blue meet the green one, the blond just smiles and fold the paper then put it on the edge of the table.

"What is it, Mika?"

"Solved. This. Problem. Or you may take another summer class while I'm having a nice vacation with Akane and the others."

Yuu let out a groan that makes the blonde giggling and start solving what he said the last problem.

"…. Ah, Yuu-chan.. Do you believe Ghoul's exist?"

Yuu reply with a simple nod and add, "Well, some of our kids end up in our orphanage because of them, right? It's weird to hear you asking me that, anyway."

Mika keeps quiet. He knew that as well, no, he truly knew that as well. He lives in Hyakuya orphanage long before Yuu came and maybe he had heard a lot of soft crying from the slightly opened door and that's the reason why his breathing became a little chaotic.

"… But.. We never exactly see them, right?" Ask Mika.

"Well.. I heard that they disguise as normal people, and kill us in the middle of the night. Maybe, you are Ghoul too, Mika." Yuu look up and find those clear crystals-blue eyes looking back at him and one simple smile that always make his heart flutters.

"Ha ha ha ha funny… You will all dead if I were one, Yuu-chan."

Mika checks his watch and quickly finish his orange juice, realizing they were late for dinner. When he tells Yuu about this, the black haired boy eating all of the remaining sandwich while gathering his belongings into his bag. He waits for Mika in front of the exit door and give a simple nod to the blue haired waitress in the back of cashier table.

"Thank you for the meal Kirishima-san!" Said Mika before he exited the café and catch up with Yuu.

There're only Yuu and Mika walking on the street.

Earlier, Yuu can hear music on Mika's favorite playlist from earphone they share together, before he hear special ringtone for a phone call from Akane.

"Um.. Sorry, Akane, I'm on my way with Mika right now. Next week we will have Math Quiz so…" Yuu hear a noise, as well as something resembling a person's—no, Akane's voice. The atmosphere is obviously different, even Mika stop and looking at Yuu with pure concern.

The intermittent voice gradually begins to form words. It makes Yuu feel cold to spine when he realizes its sound of children screaming and crying. There is quite a lot of noise mixed in, like glass shattering, something thrown to the wall and then Yuu can somehow make out a few parts.

"….. Yuu-chan…. Don't come home…. It…. Dangerous…. Please…."

Once, those words have been said, Yuu can hear many screams and enumeration of words he can't understand. He looks at Mika who look back at him with confused stares, Yuu puts down his phone and then grab Mika's hand before running towards a crescent moon, which was floating in the deep black sky, obscured by thick clouds.

"Yuu-chan, what happened?"

"… It's surely just some kind of joke, right?" Yuu whisper, in an attempt to persuade himself. He still remembers the noises and sound of his family crying and screaming in that phone call. The noises slowly become louder and louder in his head, making Yuu panic and run with all he got ignoring Mika's words and questions.

It seems like forever before they finally reach their home—Hyakuya Orphanage.

Yuu looks at Mika who stand beside him, lips are shaking and their teeth are chattering. Yuu have told him what happened earlier, and he feels the adrenaline pumping his heart into the limit after all of running and dread for what will they see beyond the front door.

Mika slowly loses his grasp and let go his hand from Yuu's.

"I will go first. You stay here and call the police or anything if I don't come back in five minutes."

"What the hell—Mika, I come with you."

"No. Stay. Here."

The boy feels his heartbeat quickens and bit his inside cheeks when he see Mika's back slowly getting farther and farther. He grabs his phone and checking the time after Mika opens the front door and come inside the building.

He doesn't wait five minutes like what Mika said. It is not even one minute past, after Mika entered the house and Yuu find himself walking towards the front gate to the garden and stand in front of the white door. He pushes the door and sees thick blood covering walls and floors with lifeless of the director's body with no hands and some part of his legs.

"There's no one left here anymore, and soon, me too…." The minute he murmurs that he hears Mika yelling voice from inside the house.

"YUU-CHAN! CALL THE AAARGH!"

Yuu finds himself running towards their shared bedroom on the second floor, ignoring the smell of blood and dead bodies with some missing limbs or head on their paths. He's not alone, Mika's there and maybe he can do something to help his only one friend and family from this disaster. Yuu wipe the tears that threaten to fall again, and take a deep breath before pushing the door in front of him.

"Mika, you there?"

The door slowly opens and giving Yuu a view of a man with long silver hair done in a ponytail, he grabs Mika by his collar while the other hand grabbing what looks like his mask. A pair of black-red eyes now look at Yuu, like those sapphire eyes that widened in fear. "Look, we have another guest." The man said then throw Mika to the corner of the room.

"Yuu-chan! GO! RUN!" Mika barked as he tried to stand up, his pure white shirt now stained with red.

"Are you here to help your little friend?" Yuu's eyes come back to the man in front of him, a smirk wide across his face.

"YUU-CHAN, RU—" before Mika can finish his sentence something that looks like a tail with a red spike like dragon skin stab right into his stomach.

"Could you shut up for one second? I'm in the middle of conversation right now?" Said the ghoul.

"MIKA!" Yuu screamed at the top of his lungs when he saw Mika vomiting the blood.

"Yuu-chan… r—run…"

"NO! I'M NOT LEAVING YOU!"

His green eyes land on blue eyes for one final time, Mika gives his sweet smile and quickly slip out from Kagune when its power loosens and head straight towards the direction of the others. "HEY, STUPID MONSTER, IS THAT ALL YOU GOT!" After Mika grabs the ghoul attention he secretly throw a gun to Yuu.

The boy successfully grabs the gun and aiming it to the head of the Ghoul, he gives a little smirk before release the safety and put his fingers on the trigger.

"Have a nice dream." He said with a low voice then pull the trigger. After this he will ask Mika where does he find this thing.

1…2…..3…..

Nothing happened.

The silver haired ghoul laugh and look at them with fake pity stare. Yuu look at Mika who just standing there with horror. They can't do anything, they can't win. Mika suddenly looks at the door, he runs and push Yuu before he close the door in front of his only one family. Yuu hear sounds of clicking and start banging the door.

"MIKA! OPEN THE DOOR! MIKA! OPEN THE FUCKING DOOR! MIKAAAA!"

However, at that moment, Yuu can no longer hear the boy's voice. But it is not because Mika stop speaking. He is beating up the door and screaming his only one family name on top of his lungs.

"MIKA! OPEN THE FUCKING DOOR! STOOOOOP! PLEASE STOOP.. HIS MY ONLY FAMILY…"

Between the sound of his hand banging and his scream he can hear Mika's screaming and sound of something shatter, then the iron smelled of blood spreading from the ventilation. His voice does not reach Mika nor the ghoul. Yuu can hear someone laugh, someone cry, someone begging for his life and sound of something like a bone breaking apart.

"Stop! Please, stop! Mika…."

That's when Yuu thinks that anything that happen today is a part of his daily nightmare. He falls to his knees and feel the dull-ache that come from his both hands. All he wants to just live a normal life after his parent throw him away, being with the person he sort as best-friend, obtaining whatever he wants, and living days happily. Argued with Mika, made Akane cries, and played with little kids in the backyards of the orphanage. Those seemed like really simple things, but yet.

"….. Mika."

The boy murmurs as falling to the ground.

He clench his fist tightly.

"….. I'm sorry, I can't help you… I can't save you… I don't have enough power."

Sorry.

If I follow what Akane told me and didn't come home.

If we were coming home early and we called the police or Ghoul Investigator.

The one who was fault on this disaster was powerless me.

Yuu hear nothing and let his tears flowing down his cheeks.

The director is dead.

The children—his little brother and sister is dead.

Akane is dead.

Mika is dead.

And it's all because of him.

"Guren-sama, Y-Yuki-chan found one survivor."

"…."

Ichinose Guren looks up at the pitch black sky with one crescent moon and no star.

A girl with pure white uniform and a big white case on her left hand and crowned with brown hair stand not far behind him. Her name is Hanayori Sayuri, and the shorter girl with long dark hair who stand beside her while giving a deep bow to Guren is Yukimi Shigure.

"He just lost consciousness because of shock, no physical injured. What should we do, Guren-sama?"

"Those Hiiragi probably doesn't need him. Can I see him for a second?"

"Of course."

Yukimi Shigure escorts Guren to one ambulance car and found a boy with messy black hair sat above the bed with one hand grabbing his head.

"One survivor from Prince's case. My name is Ichinose Guren, First Class Investigator. Nice to meet you, kid. What's Your name, anyway?"

What Guren doesn't expect is a glare full of hatred and feeling of betrayed.

"WHY DON'T YOU COME EARLIER YOU BASTARD. YOU KILL EVERYONE! YOU KILL MIKA!"

Guren raises one of his eyebrows, this brat is interesting.

"The one who kill them is you. If you call us earlier, we won't have to bring a lot of dead bodies." Then Guren looks in those empty green eyes and put a little smirk, "Oh well.. I think I would hear something about revenge, but… You just a weak one after all. You put the blame on the other, even if you were the one to blame. Don't worry, you will put into another orphanage in Kyoto in case you develop some trauma if you stay in Tokyo." He said and deciding to leave, he gives the signal to Shigure but his movement stop when one hand grabs his white coat tightly.

"Please… teach me how to kill them…. How to kill those monsters."

"Now, that's what I want to hear."
