The bands that perform the series' ending themes are also featured in the programs as being local bands in the fictional city of Fuuto: crossover rock band Labor Day's "Cyclone Effect", heavy metal/hard rock band Galveston 19's "Free Your Heat", and hip-hop group Florida Keys' "Finger on the Trigger". Each of these bands is named after a major early 20th century hurricane: the 1935 Labor Day hurricane, the 1900 Galveston hurricane, and the 1919 Florida Keys hurricane. The newest group, the visual kei band Wilma-Sidr, is named after Hurricane Wilma and Cyclone Sidr.
