Doppelgängers have infiltrated the school.
These doppelgängers perfectly mimic the appearance of the students.
You must become a school security guard and verify the identities of the students who visit every day.
Is the student in front of you truly human?
Or is it a doppelgänger who has stolen the student's appearance?
Do not judge based on appearance alone.
Even a small anomaly can be the decisive clue to uncovering their true identity.
■ Look for Suspicious Points
Observe their face and appearance closely.
Check if the information on their student ID matches and if they are a student who actually exists on the school roster.
If necessary, examine attendance records or verify directly via an internal phone line.
Do not let your guard down even if all the information seems to match.
Doppelgängers are far more cunning than you think.
■ To Allow or Isolate
The decision is yours.
If you believe they are a normal student, allow them.
If you judge them to be a doppelgänger, isolate them.
However, wrong judgments have consequences. You can isolate a normal student out of suspicion,
or you can let a doppelganger into the school.
If you are unsure, double-check.
Decisions made cannot be reversed.
■ Will you trust the records or the student in front of you?
Student ID, school roster, attendance records, internal phone lines.
Compare various clues to find lies and oddities.
Is the name strange?
Is the photo subtly different?
Does the record not match what they say?
Or… is something about their face different from a human's?
Observation is your most powerful weapon.
