So Hime needs to judge the distance between the layers, and have her attacks cross that distance for both htting and retraction before accelerator can finish calculations?

EDIT: I think that IB negates directly affects Touma. Things like Ars Magnus probably affect the world so it's like a secondary effect which IB doesn't negate too well. Maybe. So directly controlling Touma would be difficult if not impossible for Misaki.
