Ew, damn it

ew, ew, ew... and damn it again, I have to censor my first idea inspired with that...
So...
OverSword truly is telekinetic. Selectively telekinetic, but telekinetic.
Let me explain: his supernatural ability manifests itself only during a tornado.
So it’s not that often, but it can be spectacular. Once he wanted only to move his uncle’s barbecue few feet to the left and ended up moving his car and the house two miles to the left. To be honest, his uncle’s house is his car and vice versa, but still, it was remarkable achievement. And if you doubt it was only a coincidence, note that OS wanted to move the barbecue to the left and everything was moved to the left. I rest my case.
