Suzuki Suzu

Shiro and Kuroh are not the only ones who go to high school. Instead, the members of Homra (including their leader Suoh) and the members of Scepter 4 attend school together. The students are sometimes lax, but at other times, they are hot-headed.

Sai is a normal student - until one day suddenly a battle robot appears in front of him and tells him it is his mission to wipe out all humanity! If he did not succeed, the robot would pick another person to do the job. But Sai finds out that he can control the robot with his cell phone - and is determined to save humanity from its end!
