Accelerator can sense magical energy given off by people/things/active spells, so it's poooooossible? Large/concentrated amounts of it in close proximity cause him discomfort because in Toaru-verse AIM and mana are incompatible. He has a field of psychic energy around him at all times, but it's mostly just passively there unless he's in ESPer Mode. Super ridiculously powerful telekinesis.

Nana cannot sense the energy in Asbel. She does have a special telekinesis that lets her control four three-meter long selectively tangible invisible arms, though. You sort of know the drill there.

Squid Girl is completely unremarkable regarding this post. :Db
