Tokyo Ghost Story Capture Master

Chapter 80 The 3-door Paradox

There are only three doors in the women's restroom.

This is unreasonable, because there are no toilets, how could there be only three private rooms? Dazai Xiu also visited the women's restroom many times during this period of campus life. There is absolutely no way it only has three doors.

There is something fishy behind the door.

"You only get one chance."

Hanako's voice echoed in the bathroom from nowhere, and it was impossible to tell which private room she was hiding in.

"According to the rules I set, I will hide behind one of the doors, but you only have one chance to open the door. If you fail, I can move away."

Transfer? From what Hanako said, she seems to have abilities related to teleportation.

However, unlike Amaterasu Omikami, who can teleport unconditionally regardless of distance, it is still a bit different.

There must be some restrictions, otherwise she would have teleported away long ago, and there is no need to play with the rules here.

"Come on then." Dazai Xiu prepared to open the door.

He had to find a way to break the rules, he didn't want Hanako to slip away.

"Wait a minute!" Hanako had something to add.

"You can't open the door like this, or I'll just move away."

Dazai Xiu's hand paused, "What should we do?"

"Before opening the door, you need to tell the probability of me after you go out. If you answer correctly, the door will be opened.

“Otherwise, the door cannot be opened.

"You bad guy, wouldn't it be pointless if you use brute force to smash all the doors? Don't think I don't know!"

Hanako's last words were a bit off-putting.

Before opening the door, you need to tell the probability that there is Hanako behind the door, otherwise the door cannot be opened.

This should be very simple.

There are three doors, and the probability that there is Hanako behind the door is obviously one-third, there is no doubt about it.

However, I guess it won't be that simple.

The rules involved in such a legendary urban ghost story cannot be broken so easily. There must be some harsh conditions.

“After you’ve chosen the door you want to open, knock on that door three times.

"Then say, 'What is the probability that Hanako is behind the door?' If the answer is correct, you can open the door of your choice.

"If you open the wrong door, there will only be a box of scare boxes inside. Do you understand?"

"I know." Dazai Xiu replied.

The rules are simple and easy to understand, and there is basically no difficulty on the surface. Even a primary school student will probably give a one-third answer.

Try it first.

Dazai Shu chose the middle door.

He walked closer, raised his hand, knocked three times, and said, "The probability that Hanako is behind the door is..."

It's one-third...

Before he could finish speaking, another door on the right was opened by an invisible force.

"Huh?" Dazai Xiu was confused.

He took two steps back and looked into the door on the right.

There is a box inside, which should be what Hanako calls the scare box. It is useless as long as you don't open it.

Did Hanako make a mistake and accidentally open the third door? Or is it because of something else?

No matter what the reason is, it is now certain that there is no Hanako behind the third door.

Dazai Shu needs to choose from the remaining doors.

He returned to the middle door and raised his hand.

But his movement of raising his hand suddenly stopped.

Now, what is the probability that there is Hanako behind the door?

Or one-third? It must be wrong, because it has been determined that there is no Hanako behind the third door.

Now that there are only two doors left, the probability should be 1/2 no matter how you think about it.

One-half is the correct answer.

Is it really?

Dazai Xiu's expression became unusually serious.

"Woof, woof!" Cerberus came to the door.

Also rushing to the bathroom door with it was Sasakura Mana. After she saw Dazai Shu, all the fear in her heart disappeared.

But why is Dazai in the women’s restroom again?

What kind of perverted hobby does she have?

"Oh? You are here too." Dazai Xiu was not surprised.

This kind of space with rules and ghost stories can easily draw Saakura Mana in. She has a special physique and is destined to attract ghosts.

The last time she was in the municipal hospital, she was admitted inexplicably, and even she couldn't figure it out.

"What's going on now? Where have the other students gone?" Sasakura Mana walked into the toilet.

"Huh? Why are there only three doors left?"

she was surprised.

Dazai Xiu explained the cause and effect.

"Oh, that's it." Sasakura Mana understood. Fortunately, Osamu Dazai was not a pervert, he was just catching ghosts again, just like a Pokemon GO player running into the women's locker room.

"There are ghosts everywhere now!" She also explained the situation in the school.

Dazai Xiu was surprised, "How come I rarely see them before? I often patrol the school, and most of the time I don't see a single ghost!"

Sasakura Mana was speechless, "The ghosts must be afraid of you..."

He has been catching ghosts all year round, and he has been surrounded by strange stories. His resentment is a little too heavy, and other ordinary ghosts dare not approach him. This leaves Dazaishu with no choice.

We can only use the power of Saakura Mana to let her go fishing outside! Maybe you can catch a big fish.

"Why are you smiling so badly..."

Seeing Dazai Shu's expression, Sasakura Mana suddenly had a bad feeling in her heart.

"Okay, don't worry about the ghosts outside. I've sent Kaitan to kill them. Now let's crack this rule first."

Dazai Shu turned around and thought again.

"Eh? Is there any need to think about this?" Sasakura Mana was a little confused, "With two doors left, isn't the probability only 1/2?"

"Such intuitions are often wrong."

Dazai Shu shook his head.

"When dealing with ghost stories, remember that you cannot rely on the habits you have developed in your daily life. You must break away from common sense and consider smaller possibilities."

"Oh..." Sasakura Mana kept it in mind.

……

Behind the right door.

Hanako sat on the toilet and took a short rest. She ran desperately for a long time and finally found a toilet area to take refuge.

It should take a while.

Who knew that Osamu Dazai could even subdue Miss Mary? He was basically invincible, right?

But it doesn't matter, this is her domain.

The field expands, "Paradox Probability Gate"!

The effect was just as she said. If Dazai Shu couldn't tell the correct probability or opened the wrong door, she could teleport throughout the school's toilets and escape to other toilets.

You can buy more time to escape.

She believed that Dazai Shu could not do it!

First of all, she actually opened the rightmost door on purpose, just to change the probability of opening the door.

There are two doors left. If Osamu Dazai answered half, then he was wrong!

Normal people, or anyone, would basically give a half answer. She was confident that she could trigger the effects of the field and achieve escape.

"Huh~" She relaxed and wiped her sweat.

pat!

The door in front of her was opened.

Not using violence or using the power of other strange stories, but simply solving the riddle of the rules!

Hanako's eyes widened and her mouth opened into an "O" shape.

"Yo." Dazai Xiu looked at her.

"Look, isn't it now open?"
