The powers that he used were indeed far more like those of a familiar than a human's which meant that...

"If that's the case, we have something much better to take care of him. Right, Raising Heart?" she addressed her Intelligent Device while twirling it around herself, like a gymnast's baton. Once the staff-like device was firmly in Nanoha's grasp again, it had changed back to its Default Mode. A relatively small magical circle under her Nanoha's feet signaled the release of another spell; not quite as destructive as the others but still far better suited for the current situation.

"Target within optimal range," Raising Heart said as wings of cherry blossom-colored light sprouted from it.

"Lyrical! Magical!"

"Begin Sealing."

"Unidentified target, Seal it!"

Upon Nanoha's command, several [u][url=https://vignette.wikia.nocookie.net/nanoha/images/a/a5/Sealing.jpg/revision/latest?cb=20100523211657]ribbons of pink magical energy[/url][/u] appeared from a magical circle under the cloud of particles that their target turned into. They would leash around him and deactivate any and all magic powers that he may have active at the moment while preventing further usage of magic of any kind.

"Now, Raising Heart!"

"Yes, Master! Restrict Lock!" 

To make sure that the target would remain under their power, Nanoha added a bind on top of the Sealing, making sure that he wouldn't be going anywhere before he answered a few questions beginning with, "Who are you? What are you trying to do? And, why did you release air-carried toxins in the middle of a civilian area?" all asked in quick succession by Nanoha while she held him quite literally at gunpoint.

The least attempt to do anything other than talking would be replied with a point-blank Divine Buster to the face.
