Zariba (ZAT, also known as Saite Team) in all territories is the global city appearance monitoring team. Its function is to supervise and manage the city appearance and resist the invasion and destruction of all monsters and cosmic people from the earth and the universe. ZAT has branches in cities and counties all over the world, among which the Far East branch is located in the center of Tokyo, Japan, showing a huge rotating disk shape, where you can see the Tokyo Tower and Rili Valley Park. The advantage of being located in the city center is that it can find and deal with dangerous situations in time and gain the trust of the citizens better. The disadvantage is that the target is too obvious, but fortunately, it is very flexible. Once there is a threat, you can immediately launch the disk for defense.
