"Now I'm going to destroy Norman Osborn's evil personality, but the process may be painful. What do you think?"
Most of the awkwardness from the earlier misunderstanding about the family fortune had dissipated, though the blush at Harry's ears had yet to fade. He quickly composed himself and nodded solemnly at Rimuru. "I understand. As long as you can get rid of the Green Goblin personality inside my father and return him to the way he was, I agree, no matter how painful the process is."
With that clear consent, Rimuru's expression grew a little less casual.
He didn't act immediately. First, he calmly warned them both, "Let me be clear. The Green Goblin isn't an invading parasitic soul. He's a split personality born from Norman's own desires, ambitions, and violent emotions. They share the same origin, and their flesh and souls are completely bound together. Unlike an invading monster, he can't simply be cut away. The separation will affect every strand of Norman's soul, and the pain will be magnified tenfold. He'll lose control completely and go berserk. You two have to hold him down tight. If you let go, the two personalities will fuse completely, and there'll be no way to separate them then."
Peter's expression hardened, and he immediately stepped forward, ready to restrain Norman. Harry clenched his fists, his gaze utterly determined.
The next second, fine, pale-blue threads of magic spread across the floor and wound densely around Norman's limbs and head, burrowing through the pores of his skin into the depths of his soul.
Pain beyond his physical limits swept over Norman in an instant.
Before, it had only been the consciousnesses of two personalities tearing at each other. Now, his soul was being forcibly cut and split apart from within.
A hoarse, piercing scream
