Primary Lead · Confirmed
O.A. Thorp Elementary School — Chicago, IL
Bill might live in or near O.A. Thorp because of the color yellow.
The entire school building is painted a deep, unmistakable yellow — the exact same shade as Bill's triangular body.
Witnesses report that on foggy mornings, it's almost impossible to tell where the building ends and Bill begins.
Furthermore, the school's logo contains a triangular element that our analysts believe is no coincidence. Bill has been known to hide in plain sight by camouflaging himself inside architectural structures. We are treating this lead as high priority.

A DEAL IS A DEAL, KID — AND THIS SCHOOL'S MINE NOW. NICE YELLOW WALLS, AREN'T THEY?

📁 Case Background
Origin · Gravity Falls, Oregon
The Cipher Incident
Bill Cipher is a 2-dimensional dream demon from the nightmare realm, originally encountered by the Pines family in Gravity Falls, Oregon.
He was believed to be destroyed after Stanford Pines performed the Zodiac ritual and punched him inside his own mind.
However, Ace-G Bureau has reason to believe that Bill survived. His last known words — "A-X-O-L-O-T-L, my time has come to burn" — were a hidden spell, not a death cry. The axolotl confirmed it. Bill is out there. He just needed a new body. And a new school.

The Haunted Math Book Connection
Our leading theory is that Bill has been possessing math textbooks as a way to re-enter the physical realm.
Dreams alone aren't enough — he needs a host in the waking world.
Pages of Case #001 (The Haunted Math Book) showed equations that, when read backwards, spell out "BILL LIVES" in reverse cipher.
The equations also solve themselves at exactly 3:00 AM, which is peak dream-demon activity time according to our research. Bill is believed to be using the math book as a portal anchor between the dream realm and O.A. Thorp.

Do Not Make a Deal With This Suspect
Under no circumstances should any Ace-G agent shake hands with, wink at, or agree to any terms proposed by Bill Cipher.
He has a 100% deal-breaking record — meaning he always breaks them, in the worst possible way.
If he offers you power, knowledge, or extra recess time: it's a trap.
Last known victim accepted "one free answer on a math test" and woke up three days later having memorized every wrong answer in existence.
