Haruaki Azuma is border’s first sniper, currently a B-rank (formerly A-rank) and the leader of multiple generations of the Azuma Unit. Azuma is a very self-possessed individual. Though he may show emotion in dire combat situations, he is able to retain the lucidity and analytical mind which have earned him the trust and respect of many a Border agent. He has mentored several members of the organization, some of whom know him to be slier than the widespread image of him as a person incapable of underhanded tricks. After transmitting his teaching he mostly lets his students find answers on their own, limiting himself to asking questions, taking the in rank battles only after his disciples have suggested a course of action and only rarely stating his preference.
