Stein blinks, as Sota goes to hug Kaika instantly. "Well, that wasn't part of the plan." He shrugs. He had a better plan now. In fact, the only reason he'd wanted to kill Kaika was so he could dissect her, and yet he found traces of magic on her soul that confirmed a theory he'd had. There were a lot of fish in the ocean, and he was about to catch one of the biggest out there, he though, as he gestures, and binds Sota completely, tieing down his soul. He then shocks Kaika with his soul, enough to wake her u painfully. "Hello there, dear. You should have thought better of messing with me. Say do you know this man? He seems awfully worried about you." Stein smiles, as his glasses turn reflective, enforcing his aura of fear.
