Gigano Zonis (commonly mistranslated as Gigano Zomis) is a very powerful mamodo spell that Bari is able to use. It is a giant vortex strong enough to indirectly set a mamodo's book on fire. Not much is known about how exactly Gigano Zonis functions. It is approximately the size of a large warehouse. Only incredibly lucky opponents such as Zach and Kiyo are able to survive the Gigano Zonis.
