Kallister Gears, known as the Kamijo Gear Company (カミジョウ・ギヤ・カンパニー Kamijou Giya Kanpanī) in the Japanese version and also more commonly known as the KGC (ＫＧＣ Kē Jī Shī), is a family-owned corporate entity in Yu-Gi-Oh! SEVENS. They are an ancient and esteemed company who produce gears of all sizes and types for use across the globe. Valencian "Vance" Kallister is the current head of the family and company; his great-grandson Lucidien "Luke" Kallister is the current heir as the eldest son of the family.

History

Kallister Gears began over 1000 years before the series, having been responsible for inventing the water wheel. Since then they have produced all types of gears for all manner of uses and appliances. They, and by extension their current leader Vance, are old enough to remember Goha Enterprises as a group of upstarts who sprang up out of nowhere. Unlike Mutsuba Heavy Machinery, who were eventually absorbed into Goha Enterprises and made redundant, Kallister Gears have continued to flourish and maintain considerable resources.
