[Goose Boy]

Spoiler for Kinzo name:

If someone ever becomes the new kinzo ( if this is ever possible ), they have to forget their old name first as they cant have two names at the same time. Look virgilia: she had to abandon her unknown name to become beatrice, so a person who has became kinzo cant be called again by the same name. Personally I dont think that a theory like passing the name kinzo would explain the things... I prefer believing in my more wacky theory that Takano and Okonogi drugged kinzo to make him a living corpse to make him kill people and then become closer to godhood.
