Item from Puyo Puyo Fever by Sonic Team / Sega
Klug's prized red book — an ancient tome containing a sealed demon that whispers to its carrier and can possess him when conditions are right.
The Record of Sealing is not just a book — it's a prison for a demonic entity that predates Primp Town itself. The demon inside has been sealed for generations, but it's not dormant. It whispers to Klug, feeds his arrogance, encourages his study of dark magic, and waits for the moment when the seal weakens enough for possession. When it breaks free, Klug transforms into Strange Klug — a cackling, power-drunk entity that requires multiple powerful Puyo battlers to defeat. The book's connection to Primp Town's demonic history ties it to both the Dark Prince and Sig's arm, suggesting that the sealed entity may be another fragment of the same ancient demonic power. Klug treats the book as proof of his academic superiority. The book treats Klug as a convenient host.
A large, thick book bound in deep red leather with gold clasps and ornate symbols on the cover. The book pulses with a faint dark aura that intensifies when opened. Its pages contain text in an ancient script that shifts and changes. When the sealed demon stirs, the book glows from within and the clasps strain. Klug carries it under his arm like a school textbook, seemingly oblivious to its ominous energy.
