  Detecting chiral edge modes in topological materials has been intensively
pursued in experiments. However, the phenomena caused by the modes are not yet
elucidated theoretically. We study the dynamics of chiral spinon wave packets
at the edge in Kitaev-type magnets. More precisely, by relying on the exact
solvability of the models, we construct a spinon wave packet, localized edge
magnetization, which shows oriented propagation along the edge, whose behavior
is expected from the chiral character of the dispersion relation of the chiral
edge modes. In general, this approach enables us to study not only spin
transport in anisotropic magnets but also charge transport in Bogoliubov-de
Gennes-type superconductors because it does not rely on a conserved quantity.
