If there is a need for him, Genos would go. The whole school crisis bugs him, because it's so unlike everything before, and he wants to learn more.

As for skills, he brings the scanners on the table, but they obviously can't really get readings on magic. However, what they could pick up is if said magic had physical and mundane side effects (weird temperature spikes in certain areas, energy flickering, or something affecting living people and their vitals, like the energy drain).

That's of course only if there are any free spots left.
