Employed by crime lord Buppa to wipe out the Hands gang in retribution for the death of his son N'koi, Jadakins sets out brutalizing and graphically killing whomever he can get his hands on, at one point tearing out the eye of Chef Renkon with his teeth, and then leaving the man to suffer. Once his true mission comes into hand, Jadakins displays no relent in murdering whomever gets in his way—and whomever doesn't, as Jadakins kicks the Sycophantic Servant-turned-aspiring warlord Skunk into the path of an oncoming train for no reason at all after the latter safely delivers Erika to him. Compounding his pointless brutality with the implications that he may be getting far more pleasure out of his job than he should, Jadakins is seen as nothing short of a monster by the gangs of Tokyo.
