>>9380
...Ozaki slowly opens the door.

He, alongside the rest of the kids, find the mutilated corpse of the Nurse, only identifiable from her clothing. Her head had been destroyed in the same manner as the corpses before. Furthermore, both Takeshi and Yoko are absent from the room, which is covered in blood and in total disarray.

Time once again stops.

Check the body for the symbol she drew. Also stab in the armpit like the rest. Check pockets and make sure no one is hiding in the room.

>>9383
Ozaki removes her left shoe and sock, looking between her toes. Indeed, the same anime-style face she had drawn can be seen.

The armpit technique indicates that the Nurse truly is dead.

Inside her pockets is the Nurse's Key. Nothing else.

Finally, no one is found hiding in the room.

>>9384
I investigate the position the Nurse was found. I also check to make sure the door and the lock function the same as the rest.

>>9385
Her corpse is leaning upright, slumped against one of the medicine cabinets.

The door functions exactly as Classroom 1-B's door.

>>9386
I survey the room.

>>9387
The room is relatively small. There are two beds to lay on, as well as a desk covered with papers and chair for the nurse to sit at. There are curtains separating the beds from the desk, to give privacy. They are currently open.

There are also several medicine cabinets in the room, adjacent to and opposite the Nurse. Both sets have glass covers to see the medicine inside. However, the opposite cabinets have been smashed apart and torn open.

...Oddly, Ozaki does not see the doll sitting on top of any of the cabinets.

>>9388
Check the bed curtains to see if there is anything wrong with them.

Also check the desk for anything besides the papers and check the papers for anything interesting.

>>9390
There appears to be nothing wrong with the curtains.

None of the papers seem to be interesting; they are mostly medical records for the students at the school. None of their names ring any bells, though.

There is also nothing of interest inside the desk, but on top there is strangely a black thread...

>>9391
I burn a part of the black thread. telling me whether or not its hair from the smell.

>>9394
The black thread does not produce a smell. It melts and curls up into a ball when burning it.

>>9395
"Synthetic hair then. Commonly used for wigs."

I check the medicine cabinets. Check to see if anything is visibly missing from it.

>>9396
The medicine cabinets which the Nurse is leaning up against contain all kinds of medicine and chemicals. Bottles of various colors, big and small, decorate the shelves.

On the other hand, opposite the Nurse, the broken medicine cabinets contain a vast amount of shattered glass and various liquids are visible dripping out of the shelves. Broken containers are also found, each one having a putrid odor to go along with it.

>>9397
Check inside again for the remote chance some sort of trap was used to blow the cabinet up.

>>9398
Checking deeper inside the cabinet there seems to be obvious burn marks all over the inside.

There are no clear indicators for a trap, however.

>>9399
"So a trap is a possibility."

I check the beds Takeshi and Yoko were using for anything. I also check the floor and ceiling for anything as well.

>>9400
The beds have nothing unusual on them.

There is nothing weird about the ceiling. Scattered on the floor there are various bits and pieces of red cloth.

>>9401
Take a closer look at the red cloth.

>>9402
The red seems to be a natural part of the cloth rather than anything having soaked into it, such as blood.

The pieces are incredibly small, about the size of a fingertip each.

>>9403
Check the placement of the red pieces. DO they spell anything or lead some place?

>>9404
All of the pieces seem to be randomly scattered throughout the floor. They don't lead anywhere.

>>9405
I end my investigation.

"Hurry. We should check the library.

I take the Nurse's key, remains of the black thread and some of the red pieces and lock the door. I then check the blood trail in the hallway and tell the kids to be quite so I can listen to see if I hear anything in the hallway. Finally I go the library door and unlock it and enter.

>>9407
All of the kids follow Ozaki into the hallway.
They remain quiet, but Ozaki hears nothing.

Checking the blood trail, it stems from the staircase and goes directly to the library. It is undoubtedly real blood.

He then unlocks the library door and enters... the room itself is quite big, and it can't all be seen at once. There is nothing unusual upon entering.

>>9408
I tell everyone to stay together. I lock the door and then survey the part of the room I can see from here.

>>9409
All of the kids agree to remain together.

This part of the library is filled with dozens of bookshelves. Mystery, Fantasy, Sci-Fi, History, Reference Books, etc. There are plenty of tables to sit at and read the books as well.

The ceiling is also quite high, giving the room and even more spacious feel. On the ceiling are various fluorescent lights, flickering on and off.

>>9410
I tell the kids we should place a few tables and chairs in front of the door in a large pile so that if anyone tries to use the door while we are investigating we will hear something at the very least.

>>9411
Hikaru and Masaaki both grab a table and throw it against the door, smiling at the fun they're having.

Meanwhile, the girls struggle to lift up their own table, and settle for dumping four chairs near the door.

Hikaru and Masaaki finish placing the other table on top.

>>9412
Assuming I helped out I check it to confirm that it would work as I intend.

>>9413
Ozaki, having overseen the project, confirms that the blockade will work as intended.

>>9414
I take the kids with me and one by one we check each row of bookshelves. Starting with mystery of course.

"Is there any other rooms in the library? Like any back rooms or offices?"

>>9415
"No, there's just this one ro--"

...Marie looks up toward the ceiling, and immediately stops both her feet and her mouth.

>>9416
11:10

Soon, all of the other kids notice it too. Ozaki finds the corpses of Takeshi and Yoko, hanged high above the bookshelves. The ropes themselves are wrapped around a lighting fixture touching the ceiling.

The world freezes.

>>9417
I survey the area I am currently in.

>>9418
The area resembles the area near the entrance. Only the genres of books lining the shelves is different.

Aside from the hanging corpses, this scene would look perfectly normal for a library.

>>9419
[ http://www.youtube.com/watch?v=BkLmTtVaxY8 ]

...No, there was one other thing that felt out of place.

Standing on top of one of the bookshelves was a silhouette. The flickering lights failed to reveal the identity of this person.

Nonetheless, the figure stands there, perfectly still...

>>9421
"Hello? I bet you aren't frozen like the others are you?"

>>9422
"Well done, Ozaki-kun! Truly a good science teacher! And a truly delicious soul for the Youkai of the 13th Stair, Izanami, to claim! I refuse to let the Third-Ranked Higanbana eat you! You are much more fitting for the Second Rank!"

>>9423
"Second ranked? 13th Stair? I have to wonder, does that mean the last three corpses are your doing? Or is Higanbana still pulling the strings for this tale?"

>>9424
"Three...? No, just these two here. Because they stepped on the 13th step at the same time, I cursed them to fall. And then I stole them from that infirmary and brought them here, to hang them up for others to laugh at for all time! I wonder, Ozaki, are you willing to acknowledge my power?"

>>9425
"Sorry. I can still think of a few possibilities that would allow a human to commit these crime. You will need something better than that.

Although that is based on the assumption that the master key is here with you. If that is the case it would be all too easy for a human remove them from the infirmary and lock them up here."

>>9426
"Master Key? When have I ever had one of those? Are you sure you aren't just imagining things, Ozaki-kun?"

>>9427
"Who knows. It has been confirmed only three existed in the school a few hours ago, however that doesn't apply to this moment so I can incorporate it into a theory with ease."

>>9428
"It seems that cruel girl Higanbana did not properly explain things to you! On your first day here, you met many teachers, but how many of them were human? In this game, there have always been exactly three Teacher's Keys, and there always will be! Such a theory has been wrong from the start!"

>>9429
"Good. That means my real theories can work. Thanks for clearing that up."

>>9429
"Anyway lets not leave anything half explained like you said right? I have yet to investigate this room at all, which leaves a large shadow of doubt before anyone would believe your claims of being a youkai. I shall begin to investigate if you don't mind."

I climb to the top of the shelve and attempt to cut down the bodies. Before I do I make sure to survey them as I am now closer and can get a good look.

>>9431
Izanami smirks, but remains silent.

Ozaki climbs up on the bookshelves and cuts the rope. Concerning the wounds... there are some marks around their necks, presumably from being hanged. Only slight discoloration in the skin, for both of them. Additionally, the bruises on their heads and legs from the staircase incident remain visible.

>>9434
Check for greying extremities. Check inside the mouth. Smell the bodies for anything.

>>9435
The skin has turned mostly gray. Nothing weird inside the mouth. The corpses smell of almonds.

>>9437
I make a stab in the armpit, however this time check the blood to see if it is dark and thick.

>>9438
The armpit trick indicates both corpses are truly dead.

Furthermore, the blood is in fact dark and thick.

>>9439
"I thought it was like this... Looks like these bodies were not killed from being hanged but rather poison. I thought it may have been cyanide but the grayness told me otherwise. Most likely nitrobenzine, which could also explain the reason why they fell down the stairs since it can cause unconsciousness.

Your claim to being a youkai isn't look too good now eh?"

>>9441
"The cause of death doesn't matter! Just look! These corpses were teleported from one locked room to another, while all three keys were in your possession! That's the true mystery!"

>>9442
"Actually there is something odd about these corpses. They were poisoned and without any wounds besides around the neck. Yet there was a trail of blood leading here from the staircase."

I recall if the trail continued once we entered the libary and if it went to this part of the room.

>>9443
...The blood trail had stopped the moment it reached the door. Not a single drop can be found in the library.

>>9444
I recall when I lifted one of the students to the infirmary. If they smelled this strong of almonds now then I should have noticed it if they did back then.

>>9446
The student you lifted (Takeshi) did not smell of almonds back then.

>>9448
"I remember the students did not smell of almonds back when they fell down the stairs. In other words when they were in the infirmary they were not drugged and could have woken up at any time, probably after the nurse was killed and left the room. They were going down the stairs but got caught by the culprit. Of course they were then brought to this room and it was then locked from the inside.

Completely possibly for a human."

>>9449
"...So many holes with that theory. Everyone was with you, minus the three who were killed, so who killed them? And even if you find a human to pin the blame on, they must have locked the library from the inside. In that case, they must be in this room right now... There are no humans in this room which you are not aware of! Save your stupid theories for later, kid. I'm outta here."

Izanami jumps off the bookshelf he had been standing on. His cloak wraps around him, and before he can even land he has completely vanished into thin air.

>>9450
Since the world is frozen I survey the whole library.

>>9451
It's the same as before, only without Izanami.

>>9452
I check the bodies as I did the others. pockets shoes etc.

>>9453
There is nothing in their pockets/shoes to be found.

>>9454
I check the whole library for blood excluding the amount I drew from the victims.

>>9455
Not a single drop of blood is found (excluding the blood you drew).

>>9454
I check all of the bookshelves for anything. I also check the floor as well as the ceiling again.

I go up and look at what the ropes were attached to more closely.

>>9457
The bookshelves contain all kinds of books. Apart from those, nothing too interesting.

The floor is also of little interest. As already stated, the ceiling has numerous fluorescent lights. These lights are supported by fixtures, which the two ropes had been wrapped around.

>>9458
I move the tables and chairs blocking the doors and I check the door and lock to see if they are the same as the rest. I also make sure they function properly.

>>9459
The door and lock function the same as the previous ones. They do in fact function properly.

>>9460
I test to see if it's possible to lock the door with my lock pick kit.

>>9461
Ozaki attempts to lock the door with his lock-pick kit, but he miserably fails.

>>9462
I check to make sure I have all the keys.

>>9463
-Ozaki's Key
-Kanamori's Key
-Nafumi's Key
-Security Room Key
-Supplies Room Key
-Nurse's Key

>>9464
I confirm this door is the only entrance/exit to the room. I check for any vents or air ducts as well.

>>9465
After intensive searching, it is found that the door is in fact the only entrance/exit in the room.

Naturally, there are vents in the room, but not big enough for even a child to go through.

>>9466
I check for any damage done to the door. Any singe marks on the bottom? I also check to see how close the lighting fixture was to any vents.

>>9467
The door seems to be completely untouched, aside from the having been smashed by a table or two earlier.

The lighting fixtures which the ropes had been tied around are several feet away from the nearest vent.

>>9468
I recall to before I moved the tables if they had been moved from the position the students placed them.

>>9469
The tables were in the position the students had placed them.

>>9470
I recall back when we first entered the room. How far into the room did we enter before moving the tables? Did anyone from our group close the door before we decided to close the door and place tables in front of it?

>>9471
Everyone had just stepped into the room. No one had decided to mess with the door before Ozaki gave his orders.

>>9472
"Pfft oh wow. I was thinking about the wrong thing. Anyway"

I end my investigation.

>>9473

[ http://tindeck.com/listen/fdku ]

...The six students begin to shed tears upon seeing Takeshi and Yoko's corpses. They had immediately realized that the number of survivors had suddenly dwindled down almost to the level of the first murders. Whoever was the killer was certainly capable of finishing everyone off...

And for that reason, everyone stood there in silence. They stood there wondering what to do next... arriving at the conclusion that it was best just to wait things out. Soon enough, the kids dispersed throughout the room, doing separate things.

None of them felt like talking to each other.

Check the hinges on the door for any signs of tampering
Check to see if possible to lock deadbolt from outside via string or anything similar.
Check the rope that was used to tie the bodies. What was it made of? What does it look like?
Check the lighting fixtures the bodies were tied to. Check for anything odd compared to other ones.
Check the light bulbs. What kind are they and how strong are they?
Check vents for any damage.
Check the vents to see what kind of cover is on them and if possible to feed rope through it.
Try to determine where the vents would exit.
Smell the vents for an almond smell.
Check inside vents for anything.
Check the ceiling to make sure it isn't simply ceiling boards instead of a solid panel.
Recall and check for footprints other than mine on top of the bookcase. Lots of dust etc.

>>9476
There are no signs of tampering on the door hinges. It doesn't seem possible to tell how many ways the door can be locked without each individual way yourself.

The rope is made of hemp. It looks like ordinary rope.

The lighting fixture seems to have marks indicating rope had been placed there. The other lighting fixtures all have dust on them. The lights are fluorescent lamps with 15-Watt F15T8 fluorescent bulbs.

The vents show no visible damage. They are also too small to feed rope through without removing the cover, which is heavily bolted on. It seems impossible to tell where the vents lead. They don't have an almond smell, or any other unusual smell.

The ceiling is completely solid, and only your footprints can be seen on top of the bookcases.

>>9477
You also find that tampering on the door with string doesn't work.

Check to see if the students are all watching me.

>>9479
None of the students are watching you.

They have all dispersed throughout the library, either reading books or silently keeping to themselves.

>>9480
I decided to call out.

"Alright I need to investigate elsewhere than this room. Do you all feel safer staying here or do you wish to follow me? It will be either one or the other. Majority rules. I intend to lock the door if I leave although it won't take very long as I intend to return quickly."

>>9481
All of the students look up. No one says anything.

It seems they are all comfortable staying where they are.

>>9482
I leave the library and lock the door behind me. I then head to Science Lab A. I enter and lock the door behind and wait a minute to hear if anyone is in the room.

>>9483
No one is inside the room.

>>9485
I check all the potted plants for any damage or any indication that they have been used in any way. I also check the room for any used equipment.

>>9487
The room appears completely unused since you had last seen it. Everything remains as it was.

>>9489
I leave the room and go back to the library door. I make sure I'm alone and I rip out one strand of my hair. I then place it in a specific part between the door and door frame and memorize exactly where it is placed. I may open the door slightly and quietly to do so.

After I then head to the Infirmary.

>>9490
Ozaki places a strand of hair in the library door, once again locking it.

Afterward, he arrives at the infirmary. It is still in the state it was in before, with the decaying corpse of the Nurse laid up against a medicine cabinet.

>>9492
I check the shape of the pieces of red cloth. Randomly torn? Cut with something? Perfectly square? Or arbitrary shaped?

>>9493
The shaping seems completely arbitrary. No true meaning or anything behind it.

>>9494
I check if it is only red or if there is more to it. I try to piece them back together as if they were once whole.
