Vexed Melville
In my fight with Melville, I cut her in half and took her final breath afterwards. Thinking that it would be a waste to let her die for real, I preserved her still-warm body in my Inventory before I exited the mental realm.
When I went to the dungeon, I immediately took out her two halves and put them together. Since her body was fresh the moment she died, her soul was still intact in her body, so I was able to successfully resurrect her.
"Hello there, Melville."
Under the guise of Azrael, I greeted my latest prisoner, Melville, who was detained in a cell. She was obviously furious and was glaring at us, sending out her sharp killing intent.
But no matter how much effort she had exerted, she could not do anything due to the red collar that had been sealing her stats and abilities.
