Nega-Sood

Nega-Sood is the supposed twin brother of Sood, who likes dangerous business and enjoys collecting Objects. Nega-Sood can apparently detect Objects and hunts them down, destroying their owners with ruthless efficiency and claiming the Objects for himself. However, the number of Objects he owns varies, because since he is the opposite of Sood his organisational skills are awful and he's always losing Objects.

It is theorised that one of the reasons why Sood will not go anywhere near Objects is because he fears that his brother will one day come back to the Book Stop. It is said that Sood fears Nega-Sood and that if Sood and Nega-Sood were to ever meet, they would have to duel in a duel to end all duels.
