Ozone Circle (オゾンサークル) is a famous Strategic-Class Magic that's operated by William McCloud and Carla Schmidt. [1]

Ozone Circle quickly generates high concentrations of ozone gas to paralyze opponents through acute intoxication from the magic. [1] It can be used away from the target location by aiming the magic at the relative coordinates. [2]

The magic was developed through collaborative research in the EU before the division of West and East. The primary purpose was to counteract ozone holes. [1] The Magic Sequence was completed in the United Kingdom, and released to old EU countries as per the agreement. [3]

After becoming an Augmented Magician, Jasmine Williams ability to use the magic was optimized for reliability when activated. Her speed to use it is no slower than that of William McCloud. She is unable to use it on a Strategic-Class level. [2]
