That sounds very interesting. Could there possibly be like a special buster element? (Preferably wind for me ;)) But I'm curious. Do you need any help?
The students are called Buster Warriors, they're trained to fight against the robots. Since basic humans would immediately die, scientists created a suite who could ameliorate one's cells rendering you very powerful. You can pick a Buster Element(fire, water, thunder, ground, light, dark), and depending on it, you can have certain Buster Abilities.
Needs more thoughts on it now.
