|Japanese Incantation:||Gigano Reisu (ギガノ・レイス)|
| Description: Gigano Reis is Brago's third spell. An enhanced version of Reis, it creates a large, compressed gravitational well that fires from his hands.
In their first appearance, the Gigano Reis was the most powerful spell Brago and Sherry possessed. It took a full-powered Zaker attack from Zatch and Kiyo to neutralize it. However, as they gained access to more powerful spells, Gigano Reis became their most common attack against mamodo.
