Hale Particles is a Speed Type Magic that turns air molecules into ice particles, and then applies acceleration at sub-sonic levels. It is a highly efficient magic and requires a lot of power when used during summertime. Mayumi used a variant of this magic during the Speed Shooting event. The magic Hattori Gyoubushoujo Hanzou used during the finals of the Monolith Code, was "Dry Blizzard", a basic form of "Hale Particles".
During the Great Asian Union's invasion in Yokohama, Mayumi used Hale Particles (Dry Ice Pellets) as a disguise for Dry Meteor. The carbon dioxide from Dry Meteor rushed into the lungs and subdued Lu Ganghu. 
Dry Ice Pellets
This is a magic, which uses dry ice as bullets. It is described as something that has a supersonic speed enough to penetrate armor, a phenomenon impossible in nature. It is unclear whether this is the same or a variant of Hale Particles.
