Very interesting but I do worry bait on their powers, Cleo as his power effect the area around him may be to bad if you know what I mean... It's a very public school so lots of people, plants and walls will be affected which will lead to some issues. 

Karat, well her power is about finding out others weaknesses, that may be a bit too much as she can know their weakness at spot. Unless she can be backfire by it and Cleo with his powers then its hard to accept them. 

Also how did they go to Orean? 

That's all I have to say about the two.
