Chapter 21: Kaguya Shinomiya's Party Invitation
Every few years, Class 3-3 became a place where the dead returned. A student who had already died would appear as an "extra person."
The curse would rewrite everyone's memories so perfectly that no one knew who the extra person was—not even the dead themselves.
And in the years when that "extra person" existed, unless the class dealt with it, people connected to Class 3-3 would fall victim to a string of deaths.
Not supernatural slayings by ghosts, but horrifying chains of "coincidences."
A foot slipping on stairs.
A falling umbrella landing point-first at someone's throat.
One freak accident after another.
There were only two ways to end the calamity.
The first was to find and kill the dead person. By exposing contradictions in their memories, the class could confirm the identity of the "extra" and end the curse with blood.
The second was to choose a "non-existent person" to offset the extra. If the entire class treated one classmate as if they did not exist—never speaking to them, never even glancing at them—for a full year, the calamity would not occur.
But if even one person slipped up… the deaths would return.
What was more chilling was how the curse persisted through generations. Why didn't anyone ever dissolve Class 3-3 or shut down the school? Was the curse itself suppressing such thoughts? Or had those in power decided that sacrificing a group of students every few years was acceptable?
Either way, the calamity was unstoppable. Even in the original story, it never ended—only reset each year by killing the extra.
Still, readers of the diary didn't need to panic. The Mysterious Person himself admitted he only wrote about Misaki Mei because she reminded him of the eye-patched chuunibyou in the group chat.
It was "just a thrilling story," he insisted.
And even if Misaki Mei truly existed, the calamity only haunted Class 3-3. Outsiders were safe—unless they were foolish enough to transfer in.

In the grand halls of the Shinomiya estate, Kaguya Shinomiya sat with a brand-new smartphone in her hands.
Ai Hayasaka leaned over, patiently guiding her mistress through the basics. For the first time, Kaguya entered a LINE group: "Diary Fan Club."
The chat was already buzzing about today's diary entry. Kaguya scrolled first through the story, then to the chatter, her expression cool and thoughtful.
Misaki Mei. Another girl with eyes like Yotsuya Miko, yet burdened with an entirely different curse.
Two calamities already? Spirits… curses… this diary revealed too much.
Kaguya exhaled softly, brushing back her hair. She would investigate Yotsuya Miko first. Mei could wait.
Her crimson eyes flicked back to the chat, where Evil King's True Eye was loudly declaring Misaki Mei her "sworn sister" and promising to break the curse with her sealed power.
Fallen Saint Black Cat wasted no time mocking her.
> "Confirmed fake. Yours is just a contact lens. Mei's can see death. If you run over there, you'll be the first corpse."
Predictably, Evil King's True Eye launched into wild claims about her "imminent awakening," until Black Cat cut her down with one cold question:
> "You didn't actually show Ripple Breathing in front of people… did you?"
The silence that followed was deafening.
One by one, others joined the questioning. Hoshino Ai. Utako. Even Katsura Kotonoha.
Kaguya watched quietly, then typed.
Kaguya: "Don't worry too much. If leaking something would put you in danger, the diary will consume reading value to warn you. Once you've unlocked the first level of permissions, you all have that function."
Ai: "Eh? I didn't know that! You're new, right? I don't think I've seen you before!"
Kaguya: "Yes. I'm Kaguya Shinomiya. I meant to join yesterday, but my old phone couldn't install LINE. I bought this one today."
Utako: "Using your real name? Brave. None of us can afford to be careless. Your story hasn't even been spoiled by the Mysterious Person yet."
Kaguya: "It's my decision. I am the daughter of the Shinomiya House. If I can't risk even this, how can I compete within my own family? Besides, I believe we received these diaries for a reason. One day, the truth will surface. We need cooperation—even if our interests differ."
Utako: "…The Shinomiya House of the Four Palaces Conglomerate?"
Kaguya: "Correct. My father is Shinomiya Yan'an, the current head. And Ai, I believe I'm the 'Miss Kaguya' the Mysterious Person once wrote about. People have called me that since childhood."
Ai: "Eh!? Then you're my senpai! From now on, I'll call you Kaguya-senpai!"
Kaguya smiled faintly. "Just Kaguya is fine. I've watched your performances—you shine on stage."
Ai's delighted squeal filled the chat, and in that moment, Kaguya cemented her position: backed by wealth, intellect, and now a senior-junior bond with the group's founder.
But she wasn't finished.
Kaguya: "The Mysterious Person wrote about Misaki Mei today. If she really exists, and if Yotsuya Miko exists—they should have joined this group by now. Don't you agree?"
Utako: "We've seen no sign of them. Everyone who joins speaks at least once. If they were here, they'd have shown themselves."
Kaguya: "I have information on Yotsuya Miko. If she's not here, I plan to call her directly."

On the other end of Tokyo, Yotsuya Miko dragged herself home after the first exhausting day of school.
She had prayed—hoped—that classrooms would be safe. But no. She'd already seen a grotesque, four-armed spirit clutching at her best friend. She had only barely pulled it away.
She dropped onto her futon, staring at useless prayer beads strung around her wrist. Beads, charms, holy water—none of it worked. None of it.
When will this end?
Her phone rang.
She flinched, heart seizing.
An unknown number. Tokyo caller ID.
Hands trembling, she lifted it. "…Hello? Yotsuya Miko speaking."
The reply was ice-cold, emotionless:
"Are you a diary holder?"
Her breath caught. Her eyes flicked toward the black diary lying on the tatami. The one she had shoved aside, sworn never to open again. No matter where she put it, it reappeared.
"H–haha… I don't know what you're talking about. Wrong number."
She forced a laugh, forced her voice steady, and hung up.
Her imagination betrayed her instantly.
A ritual… a blood sacrifice. "You are the last. Let your blood awaken the evil sealed within the diary."
Her stomach twisted. She pressed her forehead to her pillow, whispering desperately to herself: I don't know anything. I don't know anything. Just a wrong number. Nothing more.
Minutes crawled by. The phone didn't ring again.
Shaking, she blacklisted the number, then shoved the diary under her bed with her foot, out of sight. Out of mind.
Only then did she breathe again. Today… was safe.

Back in the Shinomiya estate, Kaguya closed her phone.
She had her answer. Yotsuya Miko existed. She feared the diary.
And Kaguya would not waste such an opportunity.
If she wanted to consolidate influence within the group, she would need to draw people closer—not just through chat, but face to face.
Her lips curved. Yes. A party would be perfect.
One invitation, sent in her name, backed by the Shinomiya House.
Let them all gather under her roof.
