Kinuthia is Waiyaki’s devoted friend. When they are young, Kinuthia studies alongside Waiyaki and Kamau at the Siriana mission. After they are barred from the mission school, Kinuthia helps Waiyaki build and run his school in Kameno. Although Kinuthia wants to take action against the white people, he is extremely loyal to Waiyaki and supports him in his vision to bring education to the ridges. When Kabonyi and Kamau begin conspiring against Waiyaki, Kinuthia tries to warn Waiyaki of the danger. However, Waiyaki ultimately does not take Kinuthia’s warning seriously enough. Kinuthia fails to protect Waiyaki and Nyambura from the tribe’s zealotry or Kabonyi’s scheme, and when Waiyaki is deposed, Kinuthia thinks he should flee for his life.
