Run

Run is a member of the Jaegers and Esdeath's personal aide, wielding the Teigu Mastema. Before joining the military, he worked as a schoolteacher in a quiet town — until he returned one day to find his students slaughtered, an incident the town covered up to protect its reputation. Determined to root out the truth and change the Empire from within, he worked his way up through the ranks.

Calm, polite, and rarely ruffled, Run is willing to use deception and manipulation against his enemies, but he cares deeply for his fellow Jaegers, particularly Wave and Kurome, whom he treats almost like family. After his death in battle, his body is reanimated by Kurome's Teigu Yatsufusa as one of her puppet soldiers, remaining bound to her until it is finally freed.
