"It has been one week since Minamoto-san disappeared"

"You're right!"

"Where did he go? Is he got kidnapped?"

"Have someone just held a grudge against his family?"

"How you can be so sure about that?"

"I'm feeling pity for his parents, I hope he's safe"

Genya only stared at his classmates who have talked about the disappearance of their fellow classmates, Keisuke Minamoto. He currently stood alone near the window, as he was watching the outside.

Several days before his disappearance, Keisuke's behavior changed drastically. He became more quieter than before and rarely talked with everyone in contrast of his usual cheerful and bubbly expressions. His classmates even asked if something bad happened to him, yet he only choose to remain silent. And because of this, all of his friends were begin to feeling worry about him since then.

"Genya!"

Genya then noticed someone was addressing him. When he turned his face, it was Yae, one of his close friends.

"Yes?"

"You're not busy, right? I need some help right now" Yae requested.

"Okay" Genya nodded as he then proceeded to help Yae.

Well, no one knows what really happened to Keisuke. However, there may be another possibility if his disappearance actually have something to do with someone...or something unnatural.

...

The delinquent leader was in the pure state of panic. Most of his underlings were laying dead as they were violently murdered by an "unknown force that came from the darkness".

It was his own fault. Only because of a small, meaningless grudge, the devil tricked him to do his biddings. And now, he's going to pay a terrible price for breaching the contract that he should never involved at all.

"WHAT DO YOU WANT!? LEAVE ME ALONE!" the delinquent leader demanded in cowardly manner.

Out of sudden he felt that someone just appeared from the shadows. And when he turned behind...

Much to his own horror, the assailant was completely different from his own expectations. It was a headless man dressed in black heavy duty safety coverall full of blood stains with a pair of black rubber boots, armed with a pair of black axes.

"No...it can't be..." the delinquent leader was terrified. "

The headless ghost slowly walked closer to him.

"I knew it...that beast send you to kill us, right!? Please...please go back to your place and leave me alone! I've nothing to do with your demonic master anymore!" the delinquent leader begged desperately.

The headless slowly raised his axe on the left hand.

"You fool..." the headless ghost growled.

The delinquent leader was terrified. This headless ghost even can speak!?

"You think you can get away from Lord Tantalus? Your brain is much worse than a rotting corpse! Once you bind your soul to him, you shall serve him for eternity!" the headless ghost stated. "You may can escape from justice, but you can't hide forever from torment!"

"YOU LIAR! YOU LIAR!" the delinquent leader yelled in desperation. "I SERVE NO ONE IN MY LIFE! I DON'T EVEN FUCKING CARE IF THAT BEAST CAN SUMMON A LEGION OF DEMONS!"

"You ungrateful mortal! It's time for you to suffer in eternal damnation!!"

The headless ghost began to swing his axe against the former.

...

2:45AM.

The entire area of Kimetsu Academy was devoid of people. Yet for some unspecified reason, Fumimaru choose go inside the school compound.

A few minutes later, Fumimaru then entered an empty classroom. He soon noticed a piece of paper on one of the tables.

When he took the paper, he was a bit surprised. It was a sketch of the same headless ghost who murdered the entire gang.

Yet at the same time, Fumimaru could sensed it. The person who sketched it most probably have encountered the headless ghost before.

"Fumimaru!"

Fumimaru just realized that the Shadow Figures just teleported themselves inside the classroom. Due to their sudden appearance, they most probably came with some urgent business.

"I never expect that you folks are coming here" Fumimaru said. "Is there any important matters, gentlemen?"

"We're sorry for interrupting your time" Shadow Figure 1 apologized.

"But there are something we need to tell you" Shadow Figure 2 added.
