- "I'll be waiting for you at the Quadrangle. You'll be frozen with fear..."
- — Astaroth to Vincent in the Stray Sheep Bathroom on Day 4
The Quadrangle is the fifth level of Catherine.
- "Only those who keep their cool in this frigid blizzard will win. This stage is full of slippery ice!"
- — Colosseum Mode description
The word "Quadrangle" is the non-colloquial version of "quad," such as one seen at a university. As such, although it looks like a building from the map of the Great Trials, in reality, the stage is set in a courtyard surrounded by buildings with tall stained glass windows. Some trees are also present.
For the first time, weather becomes a factor, as a howling blizzard has now engulfed the entire area. A frigid tornado blowing blocks and sheep alike is present on each floor, and at certain points, Vincent must dodge blocks hurled from the tornado onto the tower. Ice Blocks also appear for the first time.
