On a bright morning, there was a man named Kyo, about 22 years old, who lived in a rented house. As he was walking out of the house to go to university

An object fell. When the man went to look, Discovering the body of a young woman who had fallen to her death, Kyo immediately informed the police. Then I rushed to the university because I didn't have time.

After reaching university There was a phone call from the police saying that they had not found anything at the crime scene and said various things.

The teacher's voice sounded and he told me to pick up the lecture that I had taken last time. But Kyo's bag right now, there was nothing in it. Kyo felt around to look at it.

and got cut by something from inside the bag So I tried to pick it up. It turned out to be a giant knife, stained with blood.

Everyone in the room is afraid. Quickly escape from the room.

In the room at that time There was a young woman who did not escape from the room. Maybe because of fear Kyo thought so.

Kyo then walked out of the room, but then a woman's voice rang out.

Said ''My name is Nisira, I'm stuck at Chula. What will you do next?''

Kyo answered that he didn't know because he was completely confused right now.

Nisira volunteers to take her to a secret location, which is building 1125, a storage room on the 6th floor, which is next to the school's blue gate.

As expected, 3 police cars came to this university.

Kyo was curious and asked Nisira, how long will we be here?

''It's about 1 day.'' 6th floor, storage room looks narrow. Therefore it is difficult to move. Ha...ha...

Nisira asked, I wonder why you are so dark. Is that coming too?

Kyo didn't realize that he was carrying a knife and accidentally used the knife to cut Nisira's throat.

Before dying, Nisira said a sentence, ''I secretly like you. It's been set up for a long time..''

Kyo cried and rushed out of the room. He was confused then. Nisira's face was similar to the person he met. The corpse he found before going to university that morning.

While thinking about surrendering...

A knife came and stabbed him in the back.

He turned to look.

That was the Nisira he had killed just now.

''Excuse me, ah, fresh blood, I really like it.''

Sickle was stabbed by a knife and fell from the 6th floor of the sky gate to the ground, stabbed back into the flower field, crashing so hard that he died on the spot.

And then 2 years have passed.

The man was shocked that there was nothing in his pocket and picked up a knife.

Everyone in the room rushed out of the room.

Only Nisira is left. ''I'm Nisira, stuck at Chula. Can I help you?'' ^^

Spoiler: Everyone in the room is the same as Nisira.
