|Area of Effect|
Ozone Circle (オゾンサークル) quickly uses high concentrations of ozone gas to paralyze opponents through acute intoxication from the magic. 
It can be used away from the target location by aiming the magic at the relative coordinates. 
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. The Activation Sequence was completed in the UK, and released to old EU countries as per the agreement.
