To clarify point 2; your CS says that Tsurara won't leave him alone, implying that she pursues him for one reason or another. In the circumstances (i.e. him being Touma), it is reasonable to assume that you mean that she is either constantly attacking him Misaka-style, or part of his soon-to-be harem (point 1).
Point 3 is broadly correct though; if he didn't have that then he's just an expy without Touma's signature ability. Which is better.

But I'll bow out of this discussion now, because it's out of my hands. Just my opinions on your character.
