Pizzicato is an artificial intelligence created by Ayin to manage L Corp, bear and redeem Ayin’s sins, and carry out the Seed of Light plan, but he wasn’t taught all this ahead of time like Angela was. He has no idea that he is an AI, as he has a fabricated backstory and memories that fill in his life before he came to L Corp. He has to be numb to the horrors of this facility that holds and experiments on deadly monsters, but his heart is tender.
