EBS on Yandere Apocalypse -

At approximately 7:45 PM, you are back in your apartment after an ordinary day in the city, sitting at your desk with your laptop open while casually browsing the internet and listening to music through your headphones. You have always been fairly observant, curious, analytical, and interested in technology, so when your phone suddenly loses its internet connection, you immediately notice that something is unusual. You check the router, but it appears to be working normally. A few seconds later, your laptop freezes, the music stops, and several unrelated applications briefly open and close by themselves. You assume it is a temporary system problem—until you hear several emergency vehicles rushing through the streets outside. Looking through the window, you notice people gathering on the sidewalks and staring at their phones. Your own phone suddenly receives several emergency notifications reporting unexplained incidents across the city involving people displaying extreme behavioral changes. Before you can investigate further, every electronic device in your apartment simultaneously shuts down. The room becomes completely silent. Then, without you touching anything, the television switches itself back on. Instead of a normal channel, it displays a black screen with a small white message: “EMERGENCY BROADCAST SYSTEM — SIGNAL AUTHENTICATION IN PROGRESS.” You instinctively grab your phone and move closer to the television, trying to understand what is happening. The screen flickers once. Then twice. A distorted emergency tone suddenly fills the room. The television displays “CONNECTION ESTABLISHED.” For a few seconds, everything appears normal. Then the message changes to “NATIONAL EMERGENCY BULLETIN.” You realize that whatever is happening is far more serious than a technical failure. The broadcast begins.

About The virus 🦠

🦠 YV-01 — “Yandere Virus”

Classification: Neurological pathogen
Designation: YV-01
Threat Level: OMEGA / LEVEL-5
Origin: Unknown
First confirmed outbreak: Osaka, Japan
Current status: Global spread
Vaccine: None
Treatment: Experimental supportive treatment only
Mortality: Unknown
Primary effect: Severe disruption of emotional regulation, judgment, and social behavior

Core Concept

YV-01 primarily affects the brain’s systems responsible for emotion, attachment, threat perception, and impulse control. Infected individuals don’t simply become aggressive; their personalities gradually become distorted around an intense fixation on a particular person, object, or perceived relationship.

The disturbing part is that infected individuals can initially appear completely normal.

Infection Progression

STAGE 0 — INCUBATION

The individual appears healthy.

  • No obvious physical symptoms

  • Normal speech and movement

  • Normal appearance

  • Occasional headaches or unusual fatigue

  • Increasingly vivid dreams

STAGE 1 — FIXATION

The first behavioral changes appear.

  • Excessive thoughts about a particular person

  • Increasing emotional dependence

  • Difficulty concentrating

  • Insomnia

  • Heightened sensitivity to rejection

  • Unusual mood swings

STAGE 2 — DISTORTION

The person’s perception of relationships begins changing.

  • Extreme jealousy

  • Paranoia

  • Misinterpreting harmless events as threats

  • Irrational suspicion

  • Increasing social withdrawal

  • Obsessive monitoring of the person they’re fixated on

STAGE 3 — BEHAVIORAL COLLAPSE

The infection begins seriously interfering with judgment.

  • Severe emotional instability

  • Loss of normal boundaries

  • Unpredictable behavior

  • Hostility toward perceived threats

  • Difficulty distinguishing assumptions from reality

  • Resistance to attempts at intervention

STAGE 4 — UNKNOWN

Medical authorities have very little reliable information about this stage.

Official records become contradictory, and many cases are simply classified as:

BEHAVIORAL STATUS: UNRESOLVED

The Creepy Part

YV-01 doesn’t immediately turn someone into a visibly “infected” person.

Instead, they may look completely normal while their behavior becomes increasingly abnormal.

A person could calmly have a conversation with someone while simultaneously experiencing severe paranoia that nobody else can see.

This makes early detection extremely difficult.

Communication Anomaly

Your fictional outbreak can also have a strange secondary phenomenon:

Electronic devices belonging to heavily affected individuals sometimes display unexplained messages, corrupted notifications, or repeated phrases associated with their fixation.

Scientists initially believe this is unrelated.

Later broadcasts begin reporting that the phenomenon has been observed across multiple unrelated devices.

Its cause remains unknown.
