I think Tserriednich's GSB does more than simply twist the human for lying the way Zazan does with the injection. The second beast first appears after he kills someone in his room and given his GSB's warning to Theta I think it's reasonable to assume Theta will be converted into another nen beast. The design of his GSB sort of softly suggests this by baring resemblance to the Kakin girls we see him kill in his introduction, implying that this is to be the fate of his victims.
