Obliging with Nergal's direction, Mephisto is tasked with carrying out what they discussed and picks up Leon. Having discussed how Leon had lost his powers, Mephisto mentioned how he no longer has anything to protect him. Acting as Nergal's right hand, Mephisto is loyal to him and checks what Deus and Beryl are doing. Reporting to Nergal that he has treated Leon's injuries, Mephisto has his own library-like study with shelves of medicines.
