Character Arc
Kaito Tendo is the central figure of Re:Revenge and the son of the chairman of Tendo Memorial Hospital, one of the country's largest medical institutions. Because of a strained relationship with his father, Kaito did not follow the family into medicine; instead he works as a weekly magazine reporter, keeping a deliberate distance from the hospital and the expectations that come with the Tendo name.
His careful separation from that world collapses when his father is suddenly involved in an incident. Returning to the hospital, Kaito begins to see the problems his father had been quietly managing and the maneuvering already underway over who will inherit leadership. An old promise he once made resurfaces, and he commits to defending the institution and the people he cares about rather than walking away again.
Over the run of the series Kaito moves from reluctant outsider to determined investigator, using a reporter's instincts to probe motives and expose what others would rather keep hidden. His arc is built around loyalty, suspicion, and the cost of confronting powerful people, and is portrayed in a measured, non-graphic register. Specifics should be confirmed against official episode summaries.
