Field notes found in ██
DAY 1: 10:20
Today, I (Harada) dove into a spatial abnormality which occurred on the fourth floor of the Toshin Building at 3-██-6 ██ in Tokyo's ██ District.
My team consists of four members assembled at the real estate firm's request: Imoto and Sasaki (from Imoto Land Survey Corporation), along with Suda and myself (university students studying geography).
We proceeded to the fourth floor hallway. A strange phenomenon had caused an irregular hallway extension on the fourth floor only. Its length—even just the range visible by the naked eye—already exceeded the surface area of this particular floor. The hallway's total length is unknown. We're calling this hallway Aisle A.
Now, we'll proceed deeper inside Aisle A.
DAY 1: 11:27
We kept walking through the endless hall for about an hour. Despite hearing rumors about this beforehand, I still couldn't believe it.
The hall eventually split into three paths.
We're calling them Aisles A-1, A-2, and A-3. Imoto labeled them with floor marking tape.
Unable to investigate them all, we settled on Aisle A-3. This route would avoid the foul odor emitting from A-1 and the intense heat shrouding A-2. Sasaki did, however, mention a faint mossy fragrance coming from the depths of A-3.

DAY 1: 12:30
In a hallway with almost no doors, the ones we managed to find were fused shut. External tools would also prove useless in attempts to pry them open. Seemingly an effect of the spacial abnormality...
The four of us ate chocolate bars for lunch as we walked on. Everyone seemed excited to investigate one of the many spacial abnormalities occurring across Japan.
DAY 1: 13:42
We encountered a new fork in the path. This time, it was a T-intersection. We named these paths B-1 and B-2. Imoto—who can apparently sense supernatural phenomena—felt incredibly fearful of B-1. Thus, we proceeded along B-2.
DAY 1: 14:45
Despite being aware of this stretched space phenomena to a certain extent beforehand, we all began to grow terribly anxious. I suggested turning back, to which Imoto rejected. She preferred sticking firmly to the 17:30 wrap-up time. Imoto was definitely in a frenzied state. Considering the time needed to walk back, it felt as if we'd run out of time.

DAY 1: 17:05
Sometime during our trek, we lost sight of Sasaki and Suda. I had just begun to notice them drift away as fatigue disheveled their walking pace. And before I knew it, they had both vanished.
I called out, but there was no answer. Imoto claimed they had "escaped"... Where, though?
Imoto manned the front of the line while I occupied the rear. The other two were positioned in the center. They should have passed me on their way back... Regardless, Imoto wasn't listening. She wanted to continue with just the two of us.
Was this a correct judgment call? I'm highly uneasy about this.
DAY 1: 17:47
Imoto agreed to withdraw once the wrap-up time came. But our return path was no longer in sight. The route back to Aisle A had disappeared. Halfway through, a wall severed the floor marking tape we'd placed. An unbelievable turn for the worst...
Imoto suggested finding a different escape route. I proposed waiting for a rescue squad, which sparked disagreement. I ultimately caved and proceeded along B-2 with Imoto. It's unclear whether this path leads outside.
DAY 2: 0:18
No exit in sight. My legs ache from the lengthy distance traveled by foot.
We found a lit area and decided to rest for the night. I ate a biscuit and rehydrated a little. Imoto turned completely silent. While she sat, her eyes remained fixed ahead in a daze. That cheerful personality had all but dried up...
DAY 2: 5:11
I awoke from a light sleep to find that Imoto had vanished. Her belongings, however, hadn't moved. Only her body was missing. I assumed she was using the bathroom, but an hour passed with no return. If this is a dream, I'd love to wake up now. Alone, in a place like this... How am I supposed to escape by myself?
DAY 2: 10:28
This is beyond all comprehension. The amount of forks in the road has multiplied. I'm choosing the safest-looking routes while recording my progress. However, I have no clue whether it's actually safe. I'm currently at Aisle E-11, and my sanity is waning.
DAY 2: 17:30
My legs are killing me. I'm parched. I occasionally pass little puddles on the floor. Eventually, I'll resort to lapping those up. There are stalactites protruding from the ceiling above these puddles. Could there be a water channel up there? Did those components ooze down here to create these rock formations? Are these passageways fused to a cave somewhere? Does that explain the mossy smell?
DAY 3: 3:10
Succumbing to unbearable throat pain, I stooped to the unsanitary puddle water. It reeked of clay. The water itself tasted horrid as well, but provided a sliver of relief. I haven't slept much, but I'll need to find an exit while I'm still mobile. Otherwise, I'll die.
DAY 3: 19:02
I found a pay phone embedded in the wall. All logic is out the window.
As I picked up the receiver, it connected somewhere. A person was there. I was actually talking to somebody... I cried for help. The person's name was Sudo. Kyoka Sudo. I explained my situation. During which I became emotional and started sobbing. With a somewhat saddened tone, Sudo explained how to get out.
☆How to Escape
-Advance while tapping on the walls
-In lucky cases, this can lead outside
-However, the outside won't necessarily be safe...
That's all I heard before the call terminated abruptly. Countless attempts to reconnect proved futile. A phone call shouldn't be possible here in the first place... Perhaps I was hallucinating. Still, hearing a human voice helped me relax a little.
DAY 7: 13:02
Finally found it.
A place where my arm fit through the wall. It looked like an ordinary wall, but my arm went through without any resistance. I felt cold air on the other side.
I heard Sasaki's voice echoing from deep inside. "Don't go... Don't go..." But...this path should take me outside, right? I don't want to be here anymore. I want to go home. Mom, I'm sorry.
...The writings end here.
"██ Cave" in the mountains of ██ in ██ Prefecture features a complicated layout, mostly underwater. The branched network of passageways—just wide enough for a person to squeeze through—even threaten the lives of experienced cave divers. A major Dive was carried out after faint SUR values were detected in the region. After pumping the water out, a specialized team of cave explorers dove in.
This notebook was discovered alongside a woman's body in an air pocket the size of a narrow bedroom (six tatami mats) about 1,280 meters from the cave entrance. The air pocket is at the tip of a long, narrow, and completely submerged portion of the cave only accessible by traveling underwater.
Diving gear is necessary to reach this air pocket. And yet, the woman only had light equipment.
An autopsy revealed hypoxia as the cause of death. The woman was identified as Sumi Harada, a local university student.
