Tachibana Kanade

Kanade is the student council president at the afterlife school. This places her at odds with the SSS as her responsibilities require her to suppress delinquency and other disruptive activities that the team does. The SSS initially calls her "Tenshi" since they do not know her real name. It is difficult to understand what she is thinking due to her rarely showing any outward emotions and her way of talking bluntly. Her favourite food is Mapo Tofu.
