So far, right now, I can throw you a student: this guy, Mitch! So history, mythology (well, likely this summer), and now chemistry. With fire versus water - gee, I wonder how that'll go for a chemical reaction xD He's a terrible student. Smart, but he struggles and he always has with learning. But he's trying his hardest, damnit.
As for the others, right now I'm in a bit of a character slump so I don't want to promise anything yet until I can actually bring you something to show, or else I'd feel bad.
Also, I love how the spirit guide is named Batman. That is totally adorable. :3
