Roaring Cold Wave Cannon

Roaring Cold Wave Cannon (冷気咆哮砲, Reiki Houkou Hou) is one of the Magic Tools that Aum Madaura uses. It utilizes Ice Magic. It emits a strong cold wave, which if used under the sea, can instantly freeze water and attack the opponent. She also has some of the kids from her crew to give their Magoi to the Magic Amplifying Insect, and boost this Magic Tool's power. It is similar to Judal's Ice Magic, Sarg Arsarros.
