Light Yagami and Ryuk have a complex relationship in the anime "Death Note." Ryuk is a Shinigami (death god) who drops his Death Note, a powerful notebook that allows its user to kill anyone by writing their name in it, into the human world where Light finds it. Ryuk becomes Light's Shinigami, serving as an observer and occasional source of guidance. While they are not allies in the traditional sense, their fates become intertwined as Light uses the Death Note to pursue his goal of creating a utopia free of criminals. Ryuk's role is crucial in both supporting and challenging Light throughout the series.
