|“||In The Cage, strength is both power and wealth. There are 3 types of people in this place, pure outsider Humans like both of you, Canine Lords who inherited ancient power of Lord Yama and his brothers, and Mutts like us who came and settled here after wandering the tower.||”|
The Cage (더 케이지, Deo Keiji) is a huge, tall, large-height Floating Castle which is used as "home" for the Canine People (Dog Race or Dog Kin). This Floating Ship is led by Slayer No.7 of FUG, Baylord Yama and most likely feels like "headquarters or base" of Yama for his daily activities and business.
Appearances and Design
The Cage is very huge, tall, and mostly dominated with red and white color. There are three pillars (symbolism of the Three Fangs for Baylord Brothers) on the front nose of Floating Ship. The Cage also has two wide wings. There is a red white giant massive structure below the ship which looks like animal teeth or fang.
The Cage has a very tight and safe security system. There are many Observers that doing surveillance. According to the explanation of Chang Blarode, The Cage is completely shielded and its location keeps changing, so it was difficult to track and enemies find it hard to break in. The Cage security system contains entrance code and location status. These code and location status will only be delivered in a particular way to a very few trustworthy visitors and it's never even been leaked to an insider. Even the delivered location status is not accurate, so it's almost impossible to pinpoint the exact location of The Cage.
According to Chang, "the angels" or "partners" of the "three Mad Dog" was always in charge of delivering these secret information and news update about The Cage to the Mad Dogs. So, the angels such Angel and Ron Mei will most likely have the entrance code and location status of the cage.
