It seems like this was indeed the murderer's diary.
Kamiya Mirai looked through the contents in the diary and had a general idea of what happened.
But for some reason, by just looking at the 'cruel' sentences in the diary, Kamiya Mirai felt cold all over, and fear poured out from her heart.
Withstanding the feeling of her tingling scalp, Kamiya Mirai took a deep breath and continued reading.
"I killed the Mitsui family's daughter. I waited until my parents went to work before dismembering her body. I separated her two legs and buried them deep in the front yard and backyard, the head in the courtyard, both arms under the tree, the torso…, etc. Yuuki is here. I have to go entertain her…
"Yuuki was very happy after seeing the body parts and even kissed me. I feel more and more certain that what I did was right.
"The Mitsui family next door called the police. Today, the police came looking for me and asked about places Mitsui frequented. I naturally couldn't tell these idiots what I did. But for some reason, I always feel as though Mitsui has come back to life. She seems to be calling my name…"
"I started having nightmares. Mitsui looked like a distorted monster… Heavens, why did the Mitsui in my dreams not have arms? No… I need to confirm…
"I went through the soil beneath the tree but couldn't find Mitsui's arms! Damn it… The voice in my mind started echoing again. Mitsui Mitsui Mitsui!
"It can't be! Mitsui must have come back to life! I heard her voice in the courtyard!
"I started to be afraid of sleeping. As long as I sleep, I would dream of how Mitsui looked when she died and sense that she was right next to me. Could she have been here? Peeping outside the window peeping? In my drawers? In the closet? No, I'll become crazy if this goes on.
"I dropped out of school. The school was full of unsatisfactory things. That stupid fatty Matsuzaka dared to ridicule me… Kill him, kill him, kill him!
"Yuuki came to look for me again. She is the only person in the world who cares about me. I love Yuuki, and I think Yuuki loves me too.
"Turns out that it was Yuuki who had taken Mitsui's arms away… Why? Is this…?
"I'm going to be driven crazy! I dare not sleep with the lights off! I dare not stay in an enclosed space alone! I have to find a solution! A solution that can last forever! Damn it!
"Everything is fine as long as Yuuki is around. As long as Yuuki is by my side, I can remain quiet forever.
"Yuuki said that there was a girl in the class next door who was very noisy and annoying. I have to do something for Yuuki…
"Today, I killed someone again. Yuuki wanted me to do it. The person was that girl in the class next door. The process was surprisingly simple. It took only one swing of the bat, and the chatty, noisy girl stopped moving like dead meat. She was actually incontinent, so dirty.
"I sealed her mouth forever using quicklime. Yuuki praised that I did well. But why does she always want to bring the arms away?
"School, such a huge fire. What? Yuuki was also inside? Yuuki?!
"Yuuki is dead. The culprit was not caught. This bastard!!! I must kill him!"
Kamiya Mirai was shocked by the deep hatred in the notepad. She withstood the discomfort in her heart and turned to the next page.
She only saw one sentence on that page.
"Yuuki came back to life. Turns out that there are two Yuukis… The Yuuki that only belongs to be, the Yuuki that only belongs to me…"
Kamiya Mirai swiped her fingers and wanted to read the content behind the notepad, but she did not expect that nearly one-third of the content behind was stuck together with a large amount of blood. Forcefully tearing it open would cause damage to the paper, making the content unreadable.
At this point, Kitagawa Tera's voice suddenly came from behind. "Finished reading?"
This made Kamiya Mirai, who was deeply engrossed in reading the notepad, have her hair stand and shiver in shock.
After discovering that it was Kitagawa Tera, Kamiya Mirai complained, "Really, Tera-kun, don't always scare me."
Kitagawa Tera sat next to Kamiya Mirai and asked while looking at the side of her face, "How do you feel?"
Kamiya Mirai passed the notepad to Kitagawa Tera and pondered. "Umm… How should I put it, this was basically written by someone with severe mythomania, auditory hallucinations, and mental illness?"
Her tone was slightly uncertain.
"At the beginning, the sentences and words were fairly clear, but toward the back, when the writer started murdering, you can clearly see a distinct difference. He began to display signs of mythomania and auditory and visual hallucinations. How was it possible to see someone dead in his own courtyard… Er—"
Kamiya Mirai coughed, thinking that she had already encountered many impossible things.
"There was also a main character in this diary. Apart from the diary's author, there is Yuuki." Kitagawa Tera flipped the diary open and frowned at the descriptions of 'Yuuki'.
There were some descriptions of Yuuki in the notepad, wanting to portray 'Yuuki' as a rare beauty of heaven and earth.
This obsequious attitude made Kitagawa Tera frown and shake his head.
What was written was entirely subjective and had no reference value at all.
But the last few sentences left by the notepad's owner caught Kitagawa Tera's attention.
"Yuuki came back to life. Turns out that there are two Yuukis… The Yuuki that only belongs to be, the Yuuki that only belongs to me…"
According to the notepad owner, 'Yuuki' should have been killed in a huge fire, so why did he write here that 'Yuuki' had come back to life?
Kamiya Mirai noisily stood up, leaned behind Kitagawa Tera, and asked curiously, "Could there be powers that resurrect the dead in this world, Tera-kun?"
"…" Kitagawa Tera.
Cell death was an irreversible process of life phenomena. This was the most basic knowledge for a medical student.
But there was a system in this world, and it might truly be possible that people could resurrect the dead.
"But I feel that this isn't that simple." Kitagawa Tera flipped the notepad back and forth and remained silent for a while before saying, "If 'Yuuki' really possesses extraordinary powers, she didn't need to use the diary's owner to murder."
It could be seen that the diary's owner was completely obeying 'Yuuki's' orders to murder.
Who to kill, who to make trouble for, were all just orders from 'Yuuki'.
And this 'Yuuki' was also interested in human arms…
Kitagawa Tera closed the notepad and said in a deep voice, "There's also one important piece of information in here, Hassan City.
"… Strictly speaking, it can't be considered that there was no harvest this time."
They only had to check the case files of Hassan City in recent years to find some clues.
As soon as Kitagawa Tera put the notepad into his bag, his phone rang.
He looked at the caller ID and was a little surprised.
Arano Ryoko!
