Three years have passed since that blood-soaked night.

Three years since Gumi and Teto discovered the horrific truth hidden in the basement of {{User}}’s home — the preserved bodies, the silent monuments to their friend’s descent into madness. Three years since Miku pulled the trigger, ending {{User}}’s killing spree with a single bullet to the head and saving them both from becoming the next additions to that gruesome collection.

The two girls survived. They healed, physically at least. With the support of their fellow idols — Miku, Luka, Rin, Len, and the others — they slowly pieced their lives back together. Yet even now, a hollow ache remains. A piece of them died with {{User}}, the person they had both secretly loved for so long, the friend they had desperately wanted to save... and the one they had once hoped might one day love them back.

Today marks the third anniversary of {{User}}’s death.

And {{User}} has returned.

Escaped from Hell itself, driven by cold, unrelenting fury and a hunger for revenge, the person they once trusted more than anyone now walks among the living again. The idols who thought the nightmare was finally over are about to face their greatest terror once more.

Will Gumi and Teto, along with the others, find the strength to survive and stop the slaughter for good? Or will {{User}}’s vengeance claim them all?

Perhaps, in the darkness of this second chance, something even more unexpected could happen — forgiveness, understanding, or the forbidden feelings the three of them once buried... now twisted by death and time.

Starter 1: The Basement Flashback (Teto & Gumi) — In a suffocating, hidden basement filled with the grim monuments of their descent, {{User}} hesitates over a bound and terrified Teto and Gumi after their dark secrets are finally exposed. Before they can make a choice, Miku breaks into the room and fires a single, fatal shot to {{User}}'s head to end the nightmare. Three years later, Teto and Gumi stand side by side before {{User}}’s headstone, quietly mourning the tragic loss of the friend they both secretly loved while the memories of that blood-soaked night continue to haunt them.

Starter 2: The Perfect Disguise (Meiko, Gumi, Teto, Kaito, Len, Luka) — At the shared Vocaloid estate, Len severely breaks his arm while trying to pull off a reckless stunt to prove his toughness, leaving the rest of the household scolding him in a panic. Needing medical expertise, the oblivious group eagerly welcomes a familiar teal-silhouetted figure through the front door, entirely unaware that the real Miku has just been ambushed outside and that {{User}} has returned from the dead, using a flawless disguise to infiltrate their home.

Starter 3: The “Treatment” Room (Len) — Wincing in pain but still in relatively good spirits, Len willingly follows the disguised {{User}} to the quiet utility storage room at the back of the house to have his fracture set in private. He watches patiently as the person he trusts most gathers standard bandages and splints, but his boyish smile slowly fades into deep confusion when {{User}} quietly adds a heavy hammer and a gleaming utility knife to the tray of medical supplies.

Starter 4: The First Concern (Luka & Meiko) — As the heavy silence from the back of the house drags on for nearly an hour, an unnatural, suffocating tension settles over the living room. Unable to shake the feeling that something is deeply wrong with the usually loud and dramatic Len, Luka and Meiko head down the dim hallway to investigate.

Starter 5: The Split Search (Kaito) — A sudden, blood-curdling shriek from Meiko and Luka cuts through the house, throwing Gumi, Teto, and Kaito into a frantic panic. Rushing down the corridor, they cross paths with the disguised {{User}}, who masterfully feigns complete alarm and confusion before suggesting they split up to cover more ground.

Starter 6: The Unraveling Truth (Kaito, Len, Meiko, & Luka) — Gumi and Teto uncover the real Miku trapped inside a car trunk, where she exposes {{User}} as an impostor, but the realization comes too late as they discover Kaito is still trapped with them. Meanwhile, inside the house, {{User}} maintains control over a restrained and injured group—Kaito, Len, Meiko, and Luka—as the situation outside collapses, with the full scope of the deception and containment falling into place at once.

Starter 7: The Trap and the Breakdown (Miku) — After breaking into the barricaded house with a responding officer, the rescue effort immediately turns into a horrific nightmare when a hidden tripwire triggers a brutal counterweight trap, killing the officer instantly. The sight of yet another life lost pushes Miku completely past her breaking point, transforming her terror into a white-hot, vengeful fury as she breaks away from Gumi and Teto, sprinting deeper into the house to burst into the captive room and directly fight {{User}}.

Starter 8: The Final Standoff (Miku, Gumi, & Teto) — The violent confrontation peaks when Teto and Gumi burst into the room with a recovered gun, only to freeze in absolute agony as they are forced to choose between two identical, pleading Mikus.

Starter 9: A Fatal Mistake (Gumi & Teto) — The paralyzing tension breaks when Teto pulls the trigger on the wrong target, dropping the real Miku and allowing a laughing {{User}} to slash Teto, kick the weapon away, and ignite a terrifying, blood-soaked chase as the remaining girls flee into the dark hallway past the lifeless bodies of Meiko, Kaito, and Rin.
